| 中文摘要: |
| 利用SAP2000软件对某综合办公大楼高层钢结构进行模态分析以及多遇地震下的反应谱分析和弹性时程分析，得到了结构的结构的前12阶自振周期和质量参与系数以及基本动力特性及抗震性能，说明结构布置能提供一定的抗扭刚度，保持良好的变形。全球由于地震造成的损失不计其数，且随着城市人口密度不断加大，强震带来的损害将更为严重。因此，对不规则高层钢结构的地震响研究是很有必要的。 |
| 英文摘要: |
| It was used SAP2000 to execute the modal analysis, the mode-superposition response spectrum analysis and the elastic time-history analysis to one high-rise steel structure comprehensive office building under the frequent earthquake. Then, the first 12 ranks of vibration period, mass participation coefficient of structure and the basic dynamic characteristic and the seismic behavior of structure were got, which showed that structure can provide certain torsional rigidity and possess good displacement deformation. With the increasing of urban population density, the damage will be more serious by the strong earthquake. Therefore, it is necessary to research the seismic response and energy dissipation effect of irregular high-rise steel structure. |
