摘要
泊富国际广场公寓楼高度接近规范对B级高度建筑最大容许值。原设计方案由于塔楼偏置、纵横向抗侧刚度相差较大以及竖向抗侧刚度突变等原因,导致结构抗震性能无法满足设计要求。利用MIDAS/Gen平台对结构进行了静力非线性计算与评价,并依据分析结论对结构方案进行局部调整与改进。通过对比分析发现,改进后的结构方案在抗震性能上获得了明显改善,结构构件预期性能达到目标水准。
The height of the tall apartment building of Bofu International Plaza is closed to the maximum allowed height of the specification for Class B building in the code.Due to relatively large offset at the bottom of the tower podium,a significant difference between longitudinal and transverse drift stiffness and the mutation of the vertical lateral stiffness,the structural anti-seismic performance could not meet the design requirements.A nonlinear static calculation and evaluation on the structure were done utilizing MIDAS/Gen program.According to the results,some adjustments and improvements of the structural scheme were proposed.Through the comparative analysis,the seimic performance of the modified structural scheme is better and the prospective of structural components is supposed to reach the expected level.
