本工程主体结构高68.1m,采用钢筋混凝土框架-剪力墙结构。存在扭转不规则、平面开大洞、竖向收进等多项平面及竖向不规则,属于复杂超限高层。介绍了本工程针对结构多项超限所采取的对策、多遇地震下结构整体弹性计算分析结果、罕遇地震下结构动力弹塑性时程分析结果和型钢混凝土墙柱设计及梁与柱连接节点设计。结果表明,提高结构的抗震性能目标、增强结构的抗扭刚度和竖向不规则部位的强度及延性,可保证结构的抗震安全性。
The main structure of this project is 68.1m high, using reinforced concrete frame-shear wall structure. There are irregular torsion, flat open big holes, vertical and a number of vertical and other irregular vertical plane, belonging to the complex overrun high. This paper introduces some countermeasures for the construction of a number of overrun of the project, the calculation results of the whole structure elasticity under frequent earthquakes, the structural dynamic elasto-plastic time-history analysis results of the rare earthquakes and the design of steel reinforced concrete columns and columns, design. The results show that the seismic performance of the structure can be improved, the torsional stiffness of the structure and the strength and ductility of the vertical irregularities can be enhanced, and the seismic safety of the structure can be guaranteed.
