Simple and Complex Models for Nonlinear Seismic Response of Reinforced Concrete Structures
This study investigated the possibility of simplifying the nonlinear analysis of reinforced concrete structures subjected to severe earthquakes. One thrust was a microscopic study of the particular elements of the analysis, the hysteresis model, and the development of simple models leading to acceptable results. For this phase, a multi-degree nonlinear model (LARZ) was developed to analyze rectangular reinforced concrete frames for given base acceleration records. LARZ is capable of accepting a collection of hysteresis systems, some previously used and others developed in the course of this project. The new systems generally were simpler. The second phase comprised a macroscopic study which included development of a simple model that resulted in a reasonably close estimate of nonlinear response. A given structure was viewed as a single-degree-of-freedom system which recognized stiffness changes due to the nonlinearity of material. For both phases, the reliability of the analytical models was evaluated by comparing the calculated responses with results of dynamic experiments on a group of small-scale ten-story reinforced concrete frames and frame-walls tested on the University of Illinois Earthquake Simulator.
