| 摘 要： | 通过算例分析比较 ,研究了地震波输入维数和阻尼比对巨型钢框架结构时程分析的影响。结果表明 ,对于完全对称的结构 ,也应该考虑地震波的三维输入。阻尼比对巨型钢框架结构弹塑性时程分析的影响很大 ,最好进行试算以确定阻尼比的取值。

| Abstract: | The influence of dimensions of earthquake waves and damping ratio on the response time |history analysis of mega steel frame is studied through analysis of calculation examples.The result shows that earthquake waves should be inputted from three directions even for symmetrical structures.It also shows that influence of damping ratio on elastoplastic response time |history analysis is great and it is better to determine the damping ratio of steel structures by pilot calculation. |

| Keywords: | inputting dimensions of earthquake waves damping ratio mega steel frame time-history analysis |
