【摘要】 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。更多还原

【Abstract】 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.更多还原
