摘要：苏州中级法院审判业务大楼地上7层，底部裙房为方形平面且中庭开大洞，上部塔楼为偏置的L形平面，南侧及东侧底部存在12根跨3层的穿层柱，造成结构平面及竖向均不规则，使结构超限。结构设计根据平面和竖向特点，采取三个区域剪力墙筒布置的框架-剪力墙结构体系，保证了一定抗扭刚度。采用SATWE和MIDAS Building软件建立了两个不同的模型进行了多遇地震下的弹性反应谱分析以及弹性时程分析，并将两种方法的结果进行对比。采用静力推覆法Pushover进行大震下结构静力弹塑性分析，还进行了穿层柱地震剪力和屈曲稳定分析。结果表明各项指标满足规范要求，采取的措施可行、有效，此结构方案具有较好的抗震承载能力。

Design and analysis of over-limit high-rise structure of the trial business building of Suzhou Intermediate Court
Abstract: The trial business building of Suzhou Intermediate Court has 7 floors above ground. The podium at the bottom is a square plane with a large hole in the atrium. The upper tower is an offset L-shaped plane. There are 12 through-layer columns spanning 3 floors on the bottom of the south side and the east side. Structural plane and vertical are irregular, making the structure overrun. The structural design adopts a frame-shear wall structure system with three-area shear wall tube arrangement according to the plane and vertical characteristics to ensure a certain torsional rigidity. Using SATWE and MIDAS Building software, two different models were established to conduct elastic response spectrum analysis and elastic time history analysis under frequent earthquake, and the results of the two methods were compared. The static pushover method was used to carry out the static elastic-plastic analysis of the structure under large earthquake, and the seismic shear force and buckling stability analysis of the through-layer column were also carried out. The results show that the indicators meet the requirements of the specification, the measures taken are feasible and effective, and the structural scheme has a good seismic bearing capacity.
