建筑结构非线性时程分析进展
|
摘要
非线性时程分析是目前模拟建筑结构罕遇地震性能最准确、最完善的方法,受理论水平和硬件条件所限,早期的非线性时程分析多采用了过多的简化,有悖于准确模拟的初衷。在对当前国内外非线性时程分析技术研究前沿了解的基础上,对该技术最新进展进行介绍,并重点介绍非线性骨架曲线、剪力墙模拟、软件应用、计算收敛加速问题的最新应用情况。
Nonlinear time history analysis is the most accurate method to model structural seismic response.Limited by theoretical and computational technique,much simplification have been introduced into earlier time history technique. Based on wide understanding on latest progress on time history analysis,some key issue are introduced,such as nonlinear backbone curve,shear wall modeling,software adapting,algorithm and convergence.
