Reliability Analysis of Seismic Shear-Type Structures

摘要

Statistical analysis and significance test of structural seismic response variable have shown that the story maximum ductility ratio and equivalent hysteretic loop numbers all belong to log-normal distribution. Reliability analysis method of structure under different earthquake intensities in structural serviceability limit state is put forward on the basis of results of seismic risk analysis and that of equivalent ductility damage criteria accounting for low-cycle fatigue characteristics of structures. In addition, One-order, second-moment point estimation method is used to focus the reliability analysis on reliability index for practical convenience.
