L形平面布置的钢框架结构抗震性能分析方法

Study on the seismic analysis of steel frame structure with L shape plane

以L形平面布置的钢框架结构为例,对其抗震分析方法进行了研究,研究结果表明:该类结构易诱发扭转模态,我国规范、SRSS法与30%法的计算值较接近,40%法计算值最大,以及地震动输入角度的改变对结构响应影响显著。

Taking the kind of steel frame structure with L shape plane for example,the study on the analysis under earthquake action was conducted,the results shows： it is easy to induce the torsional mode of this sort of structure,Chinese code,SRSS method,and 30% method was nearly equal,the result from 40% method was maximal,and the influence of the input angle of earthquake wave on the structural response was significant.
