This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medium- to high-rise buildings in regions of high seismicity in the USA often rely on coupled wall systems for lateral load resistance. The strength, stiffness, as well as deformation and energy dissipation capacities of coupling beams greatly influence the response of coupled wall systems. However, the high shear stresses and deformation demands coupling beams are expected to sustain during strong ground motions require the use of complex reinforcement detailing that includes large amounts of transverse and diagonal reinforcement, which makes them difficult and time-consuming to construct. Previous studies have shown that the use of a tensile strain-hardening, steel fiber-reinforced concrete (SFRC) reinforced with high-strength (330 ksi) hooked fibers at a 1.5% volume fraction allowed significant reductions of transverse reinforcement and the elimination of diagonal bars in coupling beams with span-to-depth ratios of 2.2 or greater. Despite the substantial reinforcement reduction and observed adequate coupling beam behavior, the use of SFRCs for coupling beam design has been limited in practice, in part due to experimental data on the behavior of SFRC coupling beams without diagonal bars being limited to a single fiber type and dosage. In this study, the behavior of SFRC coupling beams without diagonal bars, constructed with various SFRCs, was experimentally investigated. To this end, eight large-scale precast SFRC coupling beams without diagonal bars were tested under large displacement reversals. The main experimental variables considered were coupling beam span-to-depth ratio (3.0 and 2.0) and peak shear stress [7 to 12 [sqrt]f'[c]], fiber type, and fiber dosage. Three different hooked steel fibers and fiber volume fractions (1.0, 1.25, and 1.50%) were considered in this study for a total of six different SFRCs. Test results showed that coupling beams without diagonal bars can achieve drift capacities exceeding 5% while subjected to peak shear stresses between 6 and 10 [sqrt]f'[c]. Based on results from this and previous investigations, performance criteria for SFRCs based on ASTM C1609-12 test results were proposed. The proposed SFRC performance criteria were tied to coupling beam span-to-depth ratio and peak shear stress demand to achieve a target coupling beam drift capacity of 6%. Additionally, design recommendations that include reinforcement detailing, calculation of flexural and shear strength, and a lumped plasticity model for simulating the shear versus drift envelope response of SFRC coupling beams were proposed. The proposed model accounts for inelastic flexural rotations, concentrated rotations due to reinforcement slip, and shear sliding. The simple model showed good agreement with experimental results from this and other studies.
Book Synopsis Seismic Behavior of Coupling Beams with Multi-hook Steel Fiber Reinforced Concrete by : Mohamed Al-Tameemi

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic design provisions in the ACI 318-19 Building Code for coupling beams with span-to-depth ratio ranging between 2.0 and 4.0 require to be designed either with heavily-confined diagonal reinforcement proportioned to resist the entire shear demand or as beams in Special Moment Resisting Frames. Although diagonally-reinforced coupling beams are labor-intensive and time-consuming to construct, they are the preferred reinforcement scheme selected by design engineers because of their seismic performance and higher allowable shear stress. Because of the difficulties associated with constructing diagonally-reinforced coupling beams, researchers and structural engineers paid attention to the use of steel fiber reinforcement to simplify reinforcement detailing in coupling beams. Results from research conducted in the past two decades (Setkit, 2012 and Pe̹rez-Irizarry, 2020) have indicated that it is possible to eliminate diagonal reinforcement in coupling beams with span-to-depth ratio greater than or equal to 2.0 when adding hooked steel fibers to the concrete mix. Three types of single-hook short (1.2 or 1.4 in.) steel fibers, mostly at a fiber volume content of 1.5%, were evaluated, which has imposed a significant limitation in the application of steel fiber reinforced concrete coupling beams. In this study, Twelve large-scale coupling beams were tested under displacement reversals. The coupling beams span-to-depth ratio was either 2.0, 2.25, or 3.0. Test specimens were designed to reach a peak shear stress ranging between 68́(f'c (psi) and 108́(f'c (psi). Two types of double-hook steel fibers, at fiber volume contents of 1.0% or 1.25%, were evaluated. These fibers are almost double the length and diameter of the steel fibers used in past studies. The use of larger fibers leads to a smaller number of fibers for a given fiber volume content, which facilitates concrete mixing and pouring. Further, the production cost of the double-hook steel fibers is less expensive compared to that of the short single-hook steel fibers.

This book was released on 2012-09-25 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strain Hardening Cement Composites, SHCC hereafter, demonstrate excellent mechanical behavior showing tensile strain hardening and multiple fine cracks. This strain hardening behavior improves the durability of concrete structures employing SHCC and the multiple fine cracks enhance structural performance. Reliable tensile performance of SHCC enables us to design structures explicitly accounting for SHCC’s tensile properties. Reinforced SHCC elements (R/SHCC) indicate large energy absorbing performance under large seismic excitation. Against various types of loads, R/SHCC elements can be designed by superimposing re-bar performance and SHCC’s tensile performance. This report focuses on flexural design, shear design, FE modeling and anti-seismic design of R/SHCC elements as well as application examples. Establishing design methods for new materials usually leads to exploring application areas and this trend should be demonstrated by collecting actual application examples of SHCC in structures.

Book Synopsis Advanced Composites by : Viktor Gribniak
Download or read book Advanced Composites written by Viktor Gribniak and published by MDPI. This book was released on 2021-06-02 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering practice has revealed that innovative technologies’ structural applications require new design concepts related to developing materials with mechanical properties tailored for construction purposes. This would allow the efficient use of engineering materials. The efficiency can be understood in a simplified and heuristic manner as the optimization of performance and the proper combination of structural components, leading to the consumption of the least amount of natural resources. The solution to the eco-optimization problem, based on the adequate characterization of the materials, will enable implementing environmentally friendly engineering principles when the efficient use of advanced materials guarantees the required structural safety. Identifying fundamental relationships between the structure of advanced composites and their physical properties is the focus of this book. The collected articles explore the development of sustainable composites with valorized manufacturability corresponding to Industrial Revolution 4.0 ideology. The publications, amongst others, reveal that the application of nano-particles improves the mechanical performance of composite materials; heat-resistant aluminium composites ensure the safety of overhead power transmission lines; chemical additives can detect the impact of temperature on concrete structures. This book demonstrates that construction materials’ choice has considerable room for improvement from a scientific viewpoint, following heuristic approaches.

Book Synopsis Rate-dependence in High Performance Fiber-reinforced Cementitious Composites for Seismic Retrofits by : Kyle Scott Douglas
Download or read book Rate-dependence in High Performance Fiber-reinforced Cementitious Composites for Seismic Retrofits written by Kyle Scott Douglas and published by . This book was released on 2007 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was found that the strength, stiffness, and tensile strain capacity of the selected HPFRCC materials were significantly affected by increasing strain rate. This in turn was found to have an important influence on the lateral load capacity, drift at which softening occurred, and post-peak softening slope of the infill panels. The retrofit system was shown to decrease beam-column joint rotations, the probability of beam-column connection failure associated with these rotations, and roof and interstory drifts by up to 50%, making it a viable solution for retrofitting steel frame buildings and critical facilities.

Download or read book Resilience and Sustainability of Civil Infrastructures under Extreme Loads written by Zheng Lu and published by MDPI. This book was released on 2019-08-26 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many regions worldwide which are susceptible to extreme loads such as earthquakes. These can cause loss of life and adverse impacts on civil infrastructures, the environment, and communities. A series of methods and measures have been used to mitigate the effects of these extreme loads. The adopted approaches and methods must enable civil structures to be resilient and sustainable. Therefore, to reduce damage and downtime in addition to protecting life and promoting safety, new resilient structure technologies must be proposed and developed. This special issue book focuses on methods of enhancing the sustainability and resilience of civil infrastructures in the event of extreme loads (e.g., earthquakes). This book contributes proposals of and theoretical, numerical, and experimental research on new and resilient civil structures and their structural performance under extreme loading events. These works will certainly play a significant role in promoting the application of new recoverable structures. Moreover, this book also introduces some case studies discussing the implementation of low-damage structural systems in buildings as well as articles on the development of design philosophies and performance criteria for resilient buildings and new sustainable communities.
