Book excerpt: Many older bridges in Texas are constructed with floor systems consisting of a concrete slab over steel girders. A potentially economical means of strengthening these floor systems is to connect the existing concrete slab and steel girders using post-installed shear connectors to change the behavior of the beam from non-composite to partially-composite. Since fatigue is one of the main concerns in designing bridges, investigating the fatigue properties of these post-installed shear connectors becomes crucial. Results from direct-shear testing show that post-installed shear connectors have a better fatigue life compared to conventional welded shear studs. However, based on currently available data from direct-shear tests, fatigue life of post-installed shear connectors is still inadequate for economical retrofit in some cases. Furthermore, it is unclear if direct-shear tests provide an appropriate means of evaluating fatigue performance. The objective of this dissertation is to develop new and more accurate approaches for evaluating the fatigue characteristics of post-installed shear connectors. This objective is addressed through large-scale beam fatigue tests and computational studies. The focus of the work is on evaluating fatigue life of shear connectors based on both slip and stress demands.

Book excerpt: This thesis describes part of the work associated with Project 0-6719 sponsored by the Texas Department of Transportation (TxDOT). The primary objective of the project is to examine the feasibility of strengthening older continuous multi-span steel girder bridges through the use of post-installed shear connectors. Bridges potentially eligible for retrofit have noncomposite floor systems, where the concrete slab is not attached to the steel girders with shear connectors. Many of these bridges were designed in the 1950's and 1960's for loads smaller than the standard design loads used today. A secondary objective of the project, and the main focus of this thesis, is to examine the design of post-installed shear connectors for fatigue. Of particular interest in this study is the adhesive anchor, given its convenient installation procedure but relatively poor fatigue performance in previous tests. The objectives of this thesis were to quantify the fatigue strength of the adhesive anchor, as well as quantify the shear force and slip demands on adhesive anchors in realistic bridge conditions. In regards to the first objective, twenty-six direct shear fatigue tests were performed on adhesive anchors. Each test was conducted on a single adhesive anchor in order to capture its individual cyclic load-slip behavior. Results indicate that adhesive anchors have considerably higher fatigue strength than conventional welded shear studs, making partial composite design feasible in the strengthening of older steel bridges. In regards to the second objective, analytical and computational studies were conducted on composite beams with adhesive anchors. Results show that the shear force and slip demands are typically smaller than the endurance limits determined from direct-shear testing. This suggests that fatigue failure of adhesive anchors under service loads may not be a primary concern. Based on the results, preliminary recommendations for the design of adhesive anchors for fatigue are provided.

This book was released on 2018 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing demand for the rapid and economically efficient construction of bridges has encouraged engineers to employ the use of accelerated bridge construction through modular assembly. The replacement of vehicular bridges in highly populated areas using traditional construction methods typically results in significant social and economic impacts as a consequence of lengthy closures of these bridges during construction. Accelerated bridge construction through modular assembly offers an advantageous alternative, as it can drastically reduce the duration for which the bridge is out of service, therefore minimizing the corresponding impacts. Full-depth, precast concrete decks connected to steel girders using mechanical shear connectors is one form of accelerated bridge construction where the major components can be fabricated off-site. Employing modular bridge components takes advantage of improved quality and efficient construction through prefabrication, resulting in easier and more rapid installation on-site. Currently, welded, headed shear studs are the most common type of shear connector used in composite bridge construction. An attractive alternative to this connection type is the use of slip-critical through-bolt shear connectors as they are expected to offer advantages with regards to their reduced installation and disassembly times, as well as their fatigue performance. Currently, relatively little is known about the true static load-slip and the fatigue behaviour of slip-critical through-bolt shear connectors in composite beams. Therefore, the following research project investigates the static and fatigue performance of these connectors. In order to do this, three large-scale composite beam specimens were fabricated, instrumented, and tested in an experimental program involving both static and fatigue loading. In order to better understand the static load-slip behaviour of this connector type, a mechanistic model was also developed, along with a nonlinear finite element (FE) model of a through-bolt connection. Results of the beam tests were compared with results from a previous study employing a simpler push test configuration, in order to understand the behaviour differences resulting from the choice of test configuration. Comparisons were also made between the experimental results and load-slip predictions made using the developed mechanistic and FE models. The fatigue testing did not result in the failure of any through-bolt shear connectors for the configurations considered in this experimental program. The fatigue performance of the through-bolt shear connectors far exceeded the predicted fatigue life obtained using the current fatigue design provisions for welded, headed shear studs. The static beam test and the push test resulted in similar peak shear loads prior to the onset of failure of the through-bolts. However, the slopes of the two load-slip curves were quite different, with the through-bolt shear connectors behaving in a much less stiff manner when tested in a beam test relative to a push test. Moreover, the slip required to produce a through-bolt failure is seen to be much higher in a beam test. The static load-slip behaviour of a through-bolt push test specimen was predicted using a mechanistic model. Comparison of the load-slip curves generated by the mechanistic model with the available push test results revealed that the mechanistic model is capable of accurately predicting the load-slip behaviour of through-bolt shear connectors. A comparison of the load-slip curves generated by the FE analysis revealed that the FE models are also able to predict the load-slip behaviour of through-bolt shear connectors. The findings in this study suggest that the performance of composite bridges, in terms of fatigue life, could be significantly improved if through-bolts were used in place of traditional headed shear studs. However, further experimental testing is recommended to fully develop this connection concept.

This book was released on 2018 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current American Association of State Highway and Transportation Officials (AASHTO) Bridge Specifications assumes uniform shear flow demands at the steel-concrete interface of composite bridge girders. As stud pitch increases to beyond 24 in or as studs become clustered to account for pre-cast concrete decks, this assumed shear demand distribution may be unrepresentative. Understanding shear transfer and resulting demands on headed studs in composite beams are important for ensuring adequate composite design. This study investigates stud demands in composite bridge girders using large-scale fatigue testing and direct pressure measurements for stud force calculations. In this study, two large-scale composite beam specimens were fatigue tested to determine the effects of stud clustering on stud shear demands and fatigue life. One additional non-composite beam specimen was also fatigue tested to determine potential composite action performance and degradation following fatigue loading. All composite specimens were designed based on the stud strength limit state resulting in an expected finite fatigue life. Studs within the composite test specimens were instrumented with transverse pressure gauges capable of measuring concrete contact forces. Results from the two composite beam tests indicated that stud shear demands were lower than the AASHTO estimations (fatigue life exceeded code expectations by over 250%). Stud pressure measurements during fatigue testing indicated stud demands that were nearly 66% lower than those estimated by AASHTO. From the pressure measurements it was observed that the exterior rows of clustered shear studs felt a higher shear force than interior studs. Results from the non-composite specimen indicated composite behavior through alternative shear transfer mechanisms as a shift in the steel beam neutral axis toward the concrete slab was observed.

Book excerpt: Extensive research dating back to 1965 has been conducted on the fatigue performance of headed shear stud connectors in steel and cast-in-place composite girders. However, little research has been conducted specifically on the fatigue performance of headed shear stud connectors clustered into pockets. It seems that design provisions for pocketed shear connectors have been established assuming their performance is no different than that of continuous connectors, based on limited tests, terminated before failure, primarily on direct shear specimens that do not precisely model the loading that a shear connector is subjected to in a bridge girder. This research study investigates the fatigue behaviour of continuous and grouped shear stud connectors for cast-in-place and precast deck applications, respectively. A total of six cast-in-place and six precast composite beams have been fabricated, instrumented, fatigued to failure, and monitored in order to generate new, valuable fatigue data. This data will improve the understanding of the fatigue behaviour of headed studs in composite beam specimens subjected to static and variable amplitude loading. An autopsy program is implemented to further investigate the fatigue cracking behaviour of the shear connectors. The findings provide clear evidence that studs in precast application perform differently compared to cast-in-place as different fatigue cracking patterns were observed. Two non-linear finite element models have also been assembled in ABAQUS and compared to the results collected from the physical experiments. Additionally, a concrete shrinkage simulation is completed on the cast-in-place model to investigate its effect on the fatigue cracking behaviour. The results from this simulation are found to agree with the observed cracking patterns. S-N regression analyses are completed to determine the mean regression curve corresponding to a 50% survival probability. In this analysis, the stress ranges assigned to the studs were determined utilizing three methods that introduced three levels of conservatism. In every case, the precast specimens were found to outperform the cast-in-place in terms of fatigue performance. The findings in this study propose that the cast-in-place and precast specimens have a greater conformity with a fatigue resistance curve defined by a Category D and Category C detail, respectively. It is suggested that the design provisions governing the fatigue performance of shear connectors remains the same until a more intensive probabilistic approach is taken.

This book was released on 2017 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shear connectors are commonly used in steel bridges to join the concrete deck and steel superstructure, providing a mechanism for shear transfer across the steel-concrete interface. The most common shear connector is the headed shear stud. In the current AASHTO LRFD Bridge Specifications on composite design, shear stud fatigue often governs over static strength, and a large number of shear connectors often result. This dissertation investigates headed shear stud fatigue capacities and demands, and provides insight into conservancies in existing design specifications through examination of existing high-traffic bridge performance. To investigate stud capacity, a total of six high-cycle fatigue tests are conducted on stud pushout specimens at low stress ranges and combined with existing experimental data to develop probabilistic S-N fatigue capacity curves. Results from composite push-out specimens tested at stress ranges between 4.4 and 8.7 ksi suggest a fatigue limit of 6.5 ksi, which is near the existing limit of 7 ksi. Recommendations for modification of the existing AASHTO finite-life shear stud S-N fatigue capacity curve are proposed. In addition to experimental testing, a finite element parametric study considers the effects of stud pitch, girder depth, and girder span on shear flow demands. Results from the parametric study indicate that the shear forces within stud clusters are not captured by current AASHTO shear flow demand estimations. A new design method and updated formulation for predicting stud demands are presented. To examine high-traffic bridge performance, residual fatigue life is investigated by further fatigue testing, as well as magnetic particle inspection and dye penetrant testing on two existing bridges. The lack of discovered fatigue cracks within the studs of the bridges investigated suggests that the shear stress range estimation in AASHTO specification is higher than what is actually experienced. This discrepancy is likely due to shear transfer through adhesion and friction, which are not considered in AASHTO design calculations. Fatigue tests from sections of the decommissioned bridge exceeded the design life expectancy of approximately 850,000 cycles (at 11.6 ksi) by over 2,500,000 cycles. This evidence further indicates that stud fatigue is an unlikely failure mode during service loading.

This book was released on 2018 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, many Canadian bridges are overdue for rehabilitation or replacement. In the case of steel-concrete composite bridges, the shear connection between the concrete deck and the steel girders is a vital element of the bridge system, and has significant impacts on construction time, cost, structural integrity, and durability. The general performance of the shear connectors in these bridges is becoming an increasingly important issue, as existing bridges are used past their intended design lives, and new bridges are being designed with accelerated construction and longer service lives in mind. Welded shear studs are the standard method of shear connection in composite bridge construction, either cast-in-place or concentrated in grouted “shear pockets” in the case of steel-precast applications. The primary disadvantage of using welded shear studs in structures subjected to repeated loading is that they are believed to perform poorly from a fatigue perspective. As a result, design standards in North America require most bridges to have more than double the number of studs needed for ultimate strength purposes. This leads to construction challenges including arduous deck reinforcement placing, and it reduces the economy gained through steel-precast construction by requiring excessive numbers of shear pockets. It is possible that an enhanced understanding of the performance of welded shear studs in composite beams, including system effects, may allow for relaxed design provisions. High strength bolt shear connectors may be a viable alternative to shear studs in some cases, providing greater fatigue resistance due to the absence of welds, and having a higher material strength than conventional welded studs. The work presented herein is aimed at increasing the state-of-understanding of the fatigue behaviour and reliability of welded shear studs in both cast-in-place and precast concrete composite bridge applications, while also presenting the benefits and drawbacks of two alternative high strength bolt shear connection concepts. A laboratory research program carried out at the University of Waterloo featured the testing of eighteen large-scale beam specimens over a period of two years. In addition to the laboratory work completed by the research team, the author used finite element and reliability analysis methods to augment the test results and extend their applicability to full-scale medium span highway bridges. Over sixty stud fatigue failures and four bolt fatigue failures were observed over the course of this study, greatly adding to a dearth of existing test results, and allowing the construction of a statistically meaningful fatigue design curve of the stud detail from beam tests for the first time. System effects of multiple stud failures were studied in a finite element model of a typical highway bridge girder and revealed that the current design rules are overly conservative for all bridge classes in the Canadian Highway Bridge Design Code, and for all bridge configurations except for short spans. The results support the proposed new fatigue category dedicated to welded shear studs, recognizing the unique redundant and uninspectable nature of the detail, and suggest a fatigue endurance limit of 36 MPa (one and a half times the current limit). It is proposed that the embedded high strength bolt detail be viewed as a viable alternative to studs, given greatly increased fatigue performance and exceptional ease of deconstruction. The benefits of such a connection would be particularly useful in combination with precast deck panels.

This book was released on 2017 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of composite structures in highway bridges has become a widespread practice and for developing composite action between steel beam and concrete slab, shear connectors are widely used. These shear connectors transfer the longitudinal shear forces developed at the interface between concrete slab and steel beam. Among different types of shear connectors, headed shear stud is most commonly used in practice. The strength and ductility of these connectors greatly influence the capacity of composite structures. In bridges, these shear studs are subjected to rapidly fluctuating stresses which may result in fatigue failure during the lifetime of the structure. Thus, the fatigue resistance of shear studs in composite beams is significant for the safe of whole structure and needs to be well investigated. The aim of this research work is to investigate the load-slip behavior and fatigue life of headed shear studs and assess the strength and fatigue requirements of current Canadian Standard, CSA S6-14. A three-dimensional finite element (FE) model of push out test is developed using commercial software package ABAQUS for predicting both fatigue life and static strength of headed shear studs. The FE model included both geometric and material nonlinearities. For fatigue life prediction both fatigue crack initiation life and crack propagation life are estimated. Excellent correlation against the test results for both fatigue life and static strength of shear stud is found. After validation, an extensive parametric study has been performed to investigate the effects of different parameters on load-slip behavior and fatigue life of shear stud connectors. Results from the FE analysis were also compared with current code of practices, such as European code (EC4), American code (AASHTO LRFD), Canadian code (CSA S6-14). The parametric study showed that both AASHTO and CSA S6-14 usually overestimate the static strength of headed shear stud connectors. The design provisions of European code, EC4 is found to give conservative estimation of shear capacity of headed shear stud. For fatigue life of shear stud a significant underestimation was found in case of AASHTO LRFD, while notable amount of overestimation was observed in case of CSA S6-14 demanding more study in this area. Currently, there is no provision available for fatigue life of shear studs when they are subjected to tension. This research project also examines the applicability of the current Canadian fatigue curves for design of shear studs when they are subjected to tension.
