Abstract: Prior studies have shown that older reinforced concrete buildings designed before the introduction of the modern seismic code in the early 1970s are vulnerable to damage and collapse during an earthquake. In particular, building columns did not have the lateral strength or ductility to withstand the demands imposed by the effects of a severe earthquake ground motion, and were often the most critical components of such earthquake damage-prone structures. They were typically characterized by insufficient and poorly detailed transverse reinforcement, widely spaced stirrups and low longitudinal reinforcement ratios. The focus of this research is to develop a suitable hysteretic model that would predict the lateral deformation behavior of lightly reinforced or shear-critical columns subjected to seismic and gravity loads. Tests of reinforced concrete columns under lateral loads have shown that the total drift stems from deformations owing to flexure, reinforcement slip, and shear. The monotonic response is initially established for the separate components in order to serve as a primary backbone curve for the cyclic force-displacement relationships. Existing analytical and experimental research on lightly reinforced columns is examined. This information is used, and when required, modified to ultimately develop a suitable overall hysteretic model that would accurately predict the lateral response of this class of columns with a limited computational effort. Cyclic models are developed for each deformation component that incorporate the strength, stiffness, and energy dissipation characteristics of the structural members. The total hysteretic response was derived by coupling flexure, reinforcement slip, and shear responses as springs in series. The behavior of a column is classified into one of five categories based on a comparison of the shear, yield, and flexural strengths. The expected behavior in each category determines rules that govern the combination of the deformation components. The proposed hysteretic model is calibrated against experimental results for correlation and verification studies. Overall, the model did a reasonable job of simulating the loaddeformation relationships of shear-critical columns. It provides a suitable platform to analyze older reinforced concrete buildings with a view to determining the amount of remediation necessary for satisfactory seismic performance.

The objective of this investigation was to determine the mechanisms that lead to the collapse of reinforced concrete frame buildings subjected to earthquake forces. An empirical model was developed to estimate the drift at shear failure for existing reinforced concrete building columns. A shear-friction model was also developed. Shaking table tests were designed to observe the process of dynamic shear and axial load failures.

Seismic Evaluation, Damage, and Mitigation in Structures covers recent developments in the field of seismic performance assessment of structures. Earthquakes are one of the main natural hazards that can directly cause damage to a structure or even instigate a structural collapse, resulting in significant economic and human loss of life. In the event of an earthquake where many buildings and infrastructure components are not able to function afterward, or if extensive repair and associated disruption are needed, it can be extremely costly and take a long time to resolve. Divided into three parts, this book reviews and discusses earthquake-induced damage evaluation in structures, the repair of structural and non-structural components, and seismic damage mitigation strategies. With contributions from the leading experts in the field, this book is for earthquake engineers, structural engineers, PhD students studying civil engineering, people who can easily inspect and repair structures for quick reoccupation, and for those who understand topics such as design and damage mitigation, and limited structural or non-structural damage in seismic events. Provides effective and economical methods to assess the seismic performance of structures Analyzes earthquake damage and repair or demolition of buildings Offers future needs for constructing seismic resistant structures
