This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of corrosion on a single-bent, reinforced concrete (RC) bridge subject to seismic loading is the primary focus of this research. This work attempts to determine the effects of decreasing rebar diameter and concrete cover spalling on the strength and stiffness of the RC bridge. The application of these results to the field of historic preservation will also be explored. Through the use of static and dynamic analyses, this research shows that the effects of corrosion only have a slight influence on the seismic fragility of the RC bridge. The loss of three inches of concrete cover from the bridge column is shown to have a greater effect on the strength and stiffness of the bridge than decreasing the rebar diameter by 10%. The deformation capacity and demand both increase for bridges with reduced reinforcing steel and concrete cover; however, the capacity increases to a greater degree than the demand. The seismic fragility of the bridge based on deformation criteria is greatest for the pristine structure, and it decreases as the level of damage increases. Future work should include verifying the hysteretic behavior by accounting for reinforcement slip caused by a loss of bond.

Book Synopsis Effect of Cumulative Seismic Damage and Corrosion on Life-cycle Cost of Reinforced Concrete Bridges by : Ramesh Kumar
Download or read book Effect of Cumulative Seismic Damage and Corrosion on Life-cycle Cost of Reinforced Concrete Bridges written by Ramesh Kumar and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge design should take into account not only safety and functionality, but also the cost effectiveness of investments throughout a bridge life-cycle. This work presents a probabilistic approach to compute the life-cycle cost (LCC) of corroding reinforced concrete (RC) bridges in earthquake prone regions. The approach is developed by combining cumulative seismic damage and damage associated to corrosion due to environmental conditions. Cumulative seismic damage is obtained from a low-cycle fatigue analysis. Chloride-induced corrosion of steel reinforcement is computed based on Fick's second law of diffusion. The proposed methodology accounts for the uncertainties in the ground motion parameters, the distance from source, the seismic demand on the bridge, and the corrosion initiation time. The statistics of the accumulated damage and the cost of repairs throughout the bridge life-cycle are obtained by Monte-Carlo simulation. As an illustration of the proposed approach, the effect of design parameters on the life-cycle cost of an example RC bridge is studied. The results are shown to be valuable in better estimating the condition of existing bridges (i.e., total accumulated damage at any given time) and, therefore, can help schedule inspection and maintenance programs. In addition, by taking into consideration the deterioration process over a bridge life-cycle, it is possible to make an estimate of the optimum design parameters by minimizing, for example, the expected cost throughout the life of the structure.

Book Synopsis Influence of Reinforcing Steel Fracture on Seismic Performance of Concrete Structures by : Kuanshi Zhong

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-cycle fatigue and fracture of longitudinal reinforcing steel is a critical potential failure mode in concrete structures subjected to earthquake ground motions. Design to resist fracture depends on the reinforcing steel materials, the design details of the reinforced concrete members, and the cyclic deformation and strain demands imposed by the earthquake. Recently, concerns related to reinforcing bar fatigue and fracture have arisen due to two developments. One is the interest by the engineering and construction industry to utilize high-strength reinforcing steel materials in structures designed for regions with high seismic hazard. Since high-strength reinforcing bars tend to be less ductile and more prone to low-cycle fatigue, as compared to conventional Grade 60 bars, their adequacy for use in structures in high seismic regions needs to be confirmed. The second is related to concerns about long duration ground motions, which can increase the cyclic loading demands on steel reinforcement. Since current design methods do not explicitly consider the influences of ground motion duration, questions have been raised as to whether current seismic design requirements are adequate for structure in regions that may be affected by large magnitude earthquakes or geologic basin effects, which can lead to ground motion duration that are longer than considered in conventional designs. In the prevailing structural design and assessment methods, fatigue and fracture are only implicitly considered by checks of peak deformation measures (e.g., peak strain demand) or other proxy measures (e.g., cumulative plastic demand), which are not sufficient to resolve behavioral effects associated with material cyclic toughness and duration effects under random cyclic loading. This study (1) develops a reliable analytical framework and supporting computational tools for simulating fatigue and fracture in steel reinforcement, considering the steel material properties, reinforcing bar details in concrete structures, and random ground motion loading; (2) applies these methods to evaluate seismic design requirements for high-strength reinforcing bars, specifically Grade 80 and Grade 100 bars; (3) develops an analytical framework and algorithms for using nonlinear dynamic analysis results to systematically evaluate earthquake duration and ground motion spectral shape effects on structures; and (4) applies these methods to incorporate earthquake duration effects in the design of reinforced concrete bridge piers.
