Problems in Predicting Seismic Responses of RC Buildings

Abstract

A methodology to apply linear and nonlinear analysis rationally in the seismic design, vulnerability evaluation or upgrade design of RC buildings is presented. Some of the initial steps in this methodology are discussed and exemplified, while the remaining steps will be discussed in a separate paper. It is recommended to apply analysis to study in a step‐by‐step interactive manner the bounds of critical section, the critical element, and the complete structural response as a structure is loaded to failure under static load increments which are monotically and simultaneously applied in both lateral directions. This analysis procedure is assessed to be more rational than conducting time‐history analyses of detailed models. The reliability in the bounds of generated static response would naturally depend on perceiving and accurately modeling all the critical local and global mechanisms which influence response. Some of the parameters and mechanisms which significantly influenced the test response of idealized assemblies and building specimens are described. The influence of these parameters and mechanisms on element response bounds is illustrated.
