PEAK GROUND VELOCITY SENSITIVE DEFORMATION DEMANDS AND A RAPID DAMAGE ASSESSMENT APPROACH

摘要

The effect of peak ground velocity (PGV) on the maximum inelastic deformation demand of simple, non-degrading structural systems is studied. Ground motion data sets are assembled for pre-defined ranges of PGV and they are used to conduct nonlinear response history analysis of single-degree-of-freedom (SDOF) systems. The study is focused on short and intermediate periods of vibration (T) and strength reduction factor (R) is used to define the lateral capacity of the structure. As part of the study, a simple tool for rapid damage assessment in pre-earthquake evaluation of existing building systems is proposed that combines the ground motion parameter PGV with structural properties R and T.
