摘要

对南通的吉斯达海门商务馆大跨屋盖结构分别采用SRSS法、百分比法、规范法对地震动分量进行组合,并与三维地震动联合输入的结果比较,表明规范法不适用于组合竖向地震控制的反应,SRSS法和百分比法总体比较准确,但个别反应误差较大,建议大跨屋盖结构地震动反应分析时应采用三维联合输入时程分析法。同时研究了三维地震动输入角度对反应的影响,对屋盖结构的控制性反应有必要进行最不利角度分析。
The reactions from the combination methods including SRSS,percengtage method and the rule in the code are compared with the ones from time history for the multiple earthquake.The result indicates that the rule in the code isn't suitable for the reactions mainly induced by vertical earthquake.SRSS and percengtage method are more accurate,however the time history for multiple earthquake is suggested to check the results from those combination methods.Moreover,the relationship between the input angle of earthquake excitation and the structural responses is analyzed,and it suggests that the analysis for worst angle is necessary for the major reactions.
