苏州工业园区公积金大厦超限高层的结构设计中,通过对结构方案的合理布置,将两个L形平面联合在一起,使两个以扭转为主振型的结构变为一个以平动为主振型的整体结构,结构的抗震性能得到了根本改善。大开洞楼板平面内应力分析结果显示,楼板平面内应力水平可满足设计要求。开洞双连梁的等效方式和受力性能分析结果表明,双连梁可有效地提高筒体的整体受力性能,兼顾了结构对筒体的延性和刚度要求。 Suzhou Industrial Park provident fund building overrun high-level structural design, through the rational arrangement of the structural plan, the two L-shaped plane together, so that the two torsional vibration-oriented structure into a mainly translation The overall structure of the vibration mode, the seismic performance of the structure has been fundamentally improved. The results of stress analysis in the large open floor slab show that the stress level in the slab floor can meet the design requirements. The analysis of the equivalent mode and the mechanical behavior of the double girder with open hole shows that the double girder can effectively improve the overall mechanical performance of the cylinder and take into account the ductility and stiffness requirements of the cylinder.
