Available in PDF, EPUB and Kindle. Book excerpt: Corrosion is one of the main causes of deterioration of bridges. Structures exposed to harsh environmental conditions are subjected to time-variant changes of their load-carrying capacity. Thus, there is a need for an evaluation to accurately assess the actual condition and predict the remaining life of a structure. System reliability can be used as an efficient tool in evaluation of existing structures. The traditional approach is based on the consideration of individual components rather than the system as a whole. However, it has been observed that the load-carrying capacity of the whole system often is much larger than what is determined by the design of components. Quantification of this difference is the scope of this study.

Book Synopsis Reliability of Structures, Second Edition by : Andrzej S. Nowak
Download or read book Reliability of Structures, Second Edition written by Andrzej S. Nowak and published by CRC Press. This book was released on 2012-12-20 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliability of Structures enables both students and practising engineers to appreciate how to value and handle reliability as an important dimension of structural design. It discusses the concepts of limit states and limit state functions, and presents methodologies for calculating reliability indices and calibrating partial safety factors. It also supplies information on the probability distributions and parameters used to characterize both applied loads and member resistances. This revised and extended second edition contains more discussions of US and international codes and the issues underlying their development. There is significant revision and expansion of the discussion on Monte Carlo simulation, along with more examples. The book serves as a textbook for a one-semester course for advanced undergraduates or graduate students, or as a reference and guide to consulting structural engineers. Its emphasis is on the practical applications of structural reliability theory rather than the theory itself. Consequently, probability theory is treated as a tool, and enough is given to show the novice reader how to calculate reliability. Some background in structural engineering and structural mechanics is assumed. A solutions manual is available upon qualifying course adoption.

This book was released on 2024-01-08 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an open access book.As society progresses and the city scale increases, architecture is diversifying and becoming complex, with structures transforming from simple structures into high-rise, long-span and even special and complex structures. Architecture is where people live and work, so its security must be ensured. However, the architectural structure is likely to be destroyed by natural disasters (earthquakes, wind, snow, rain), man-made faults and incidents (explosion, fire, crashes) and accidental events like attacks and man-made sabotage in recent years. Therefore, countries have endeavored to improve architectural security for many years. A large number of anti-seismic issues in the civil engineering construction have turned up, which also gave birth to many new anti-seismic theories, technologies and products. 2023 5th International Conference on Structural Seismic and Civil Engineering Research (ICSSCER 2023) will be held on August 25–27, 2023 in Nanjing, Jiangsu, China. With a display of the latest research outcomes in theoretical research, experimental study and engineering application, this conference creates a platform for scholars, researchers and technical personnel to exchange ideas and further understand each other. We extend a warm welcome to you and expect you to attend this academic feast to promote academic exchanges of relevant issues and advance the development of structural anti-seismic and civil engineering research and application. 2023 8th International Conference on Ecological Building and Green Building Material (EBGBM 2023,http://www.ebgbm.net/) will be conducted as a sub session of ICSSCER 2023. Scholars from home and abroad are welcomed to contribute papers and attend the conference.

This book was released on 2020 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge - girder deterioration model is formed based on diffusivity process, corrosion development, and cracks propagation. The chloride diffusivity is studied based on previous researches0́9 experimental work while corrosion penetration is analyzed based on mathematical model. Corrosion products cause cracks then spalling. Therefore, in the few decades, the utilize of fiber-reinforced polymer (FRP) materials to strengthen highway bridges has obtained in popularity. sensible cost, speed and ease of installation, and limited disruption of the use of the structure have shared to the adoption of FRP systems over other strengthening options. In order to reduce the corrosion with the bridge deterioration. Fiber Reinforced Polymer (FRP) is one of the top solutions to reduce corrosion and strengthen bridge - girders, by placing FRP on the side(s) of the reinforced concrete beam and reduce the influence of chloride diffusivity through reinforced concrete. Thus, the deterioration with reinforced concrete based on corrosion with section warped with FRP is less than with the corrosion of reinforced concrete section unwrapped with FRP. The objective of this study is to develop a reliability - deterioration model based on corrosion in steel, concrete cover spalling, and FRP debonding. The reliability is reduced due to two independent deterioration factors that developed simultaneously with Life Cycle Time (LCT). The corrosion in steel rebar is the first deterioration factor that causes reduction in flexural moment capacity, and spalling. Moreover, the second deterioration factor is the surrounded environment that may causes FRP debonding. Monti Carlo Simulation (MCS) of reliability-based deterioration model is programmed and used in order to compute failure probability by using FORTRAN 90 to analyze the bridge 0́3 girder model including all design parameters.
Book Synopsis Prediction and Prolongation of the Service Life of Weathering Steel Highway Structures by : Neal R. Damgaard
Download or read book Prediction and Prolongation of the Service Life of Weathering Steel Highway Structures written by Neal R. Damgaard and published by . This book was released on 2009 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weathering steel is a high-strength, low-alloy steel which has been proven to provide a significantly higher corrosion resistance than regular carbon steel. This corrosion resistance is a product of the small amounts of alloying elements added to the steel, which enable it to form a protective oxide layer when exposed to the environment. The main advantage of its use in bridges is that, under normal conditions, it may be left unpainted, leading to significantly reduced maintenance and environmental costs. Weathering steel has been a material of choice for highway structures for almost half a century, and a very large number of structures have been constructed with it. Although its use has for the most part been successful, it has also become evident that, in circumstances where there is the presence of salt and sulphur oxides, its performance is deficient. In these situations the corrosion penetration rate is much higher than expected, and the oxide layer forms in thick layers. This presents an added risk, since these layers flake off and fall onto the roadway. The degree of corrosion on structures can be very different, even if the structural type, location, and climate are similar. Therefore the focus of the thesis is on the lifespan of weathering steel highway structures. Primarily this research is concerned with the effect of corrosion on the integrity of these structures, as well as ways of quantifying corrosion loss and protecting the structure from further corrosion. In order to determine the lifespan of weathering steel highway structures subject to different rates of corrosion, a probabilistic structural analysis program has been developed to assess the time-dependent reliability of the structure. This program used iterative Monte Carlo simulation and a series of statistical variables relating to the material, loading, and corrosion properties of the structure. A corrosion penetration equation is used to estimate thickness loss at a selected interval, and the structural properties of the bridge are modified accordingly. The ultimate limit states of shear, moment, and bearing, and the fatigue limit state of web breathing, are taken into account. Three types of structures are examined: simply-supported box and I-girder composite bridges, and a two-span box girder bridge. Based on the structural analysis of the corroding bridge structures presented herein, it can be seen that corrosion to the weathering steel girders can cause reduced service lives of the structures. I-girder bridges are shown to be more susceptible to corrosion than box girder bridges, with continuous box girder bridges showing the best performance. The amount of truck traffic does not affect the reliability of the bridge. The short-span and high strength steel bridges are more susceptible to corrosion loss, primarily because their girders have thinner sections. A two-lane bridge also has better performance than the wider bridges because the weight of the barriers and sidewalks is carried by fewer girders, so these girders are stockier. The web breathing limit state is less significant than the combined ultimate limit states. Lastly, and most importantly, inspection data from a highway bridge is used to demonstrate the benefit that can be derived from using field data to update the time-dependent reliability. The ultrasonic thickness gauge (UTG) is a common tool for thickness measurement of steel sections. When used to measure weathering steel, this instrument provides accurate data about the depth of corrosion pits, but not their lateral dimensions. The measurement does not include the corrosion layer on the opposite side of the plate from the one being measured; however, if the corrosion layer is on the measured face, a disproportionate increase in the measured thickness can be seen. In order to prevent or minimize corrosion loss, the steel is currently painted, a process with several environmental and financial disadvantages. Therefore, three novel protection methods have been assessed in a cyclic corrosion test: a zinc metallizing, an aluminum-zinc-indium alloy metallizing, and a zinc tape with a PVC topcoat. All these coatings are designed to act not just as barriers, but also as sacrificial anodes. The test was run for 212 24-hr cycles, over the course of which the all the coatings were proven effective at protecting the steel substrate, regardless of steel type and surface roughness and pretreatment. In conclusion, the threat to all types of weathering steel highway structures by contaminant-induced corrosion is significant, but inspection data permits a more accurate prediction of time-dependent reliability for a structure, and protective coatings are a promising method of slowing the advance of corrosion.
