| 摘 要： | 以二阶弹性分析方法理论为基础,建立了非线性二阶微分方程,按照输入不同地震波维数和阻尼比两种情况分析了钢框架结构的地震响应.利用MIDAS软件对结构进行多遇地震作用下的弹性时程分析和罕遇地震作用下的弹塑性时程分析,表明地震波输入维数(单向地震波和双向地震波)、阻尼比对结构的抗震性能有较大影响,并根据分析结果提出了相应的建议.

| Abstract: | The nonlinear second order differential equations are written about the second-order elastic analysis method theory,and the factors on seismic response of the steel frame are analyzed with the different dimensions of earthquake waves and damping.The result by MIDAS software shows that the influence of dimensions of earthquake wave including unidirectional earthquake wave and bidirectional earthquake waves and damping ratio could be affected greatly when analyzing the elastic time history for the frequent ea... |
