| dc.description.abstract | An important aspect of performance-based design methodologies can be regarded as the accuracy of predictions of seismic demands parameters. Making improvements to this aspect of the design-based methodologies is undeniably desirable. Recently, several Enhanced Pushover Analysis (EPA) procedures that take into account the influence of higher modes have been proposed. As most of these procedures have been applied to regular building frames; there remains a need to verify the efficiency of such procedures on the evaluation of irregular building frames. The EPA procedures, namely the Consecutive Modal Pushover (CMP), Dynamic Load Pattern (DLP), and SingleāRun Multimode Pushover (SMP), have been applied to regular steel moment resisting frames in literature. The purpose of this study is to comparatively assess the efficiency and capability of these EPA procedures to estimate the seismic demands of twelve regular and irregular special reinforced concrete (RC) moment-resisting frames having various number of stories (4, 8, 12, 16, 20, and 24). The structural responses given by the EPA methods are then compared with the benchmark results achieved from the Nonlinear Time History Analysis (NLTHA). For the sake of comparison, the conventional pushover analyses based on the first-mode and uniform lateral load pattern are also demonstrated. The results indicate that the DLP and CMP methods can predict the seismic demands of regular and irregular buildings with a higher level of accuracy than the SMP procedure. Consequently, the DLP and CMP procedures were found to be better alternatives for obtaining practically reasonable estimations of seismic demands of building frames where the influence of higher modes is significant. | |
