摘要
在巨型结构体系的基础上提出巨型钢框架-双钢板组合剪力墙住宅体系。基于实际超高层混凝土住宅工程背景建立高度为156 m的计算模型,对其进行弹性反应分析及弹塑性时程分析以评估结构力学性能。通过对比主次结构不同的连接假定,探究主次结构连接方式对于结构整体性能及关键结构构件的影响。基于ABAQUS软件分析了次结构与双钢板组合剪力墙之间采用不同连接方式对剪力墙各部件的影响。最后对该结构体系进行经济性分析。研究结果表明:该结构体系能满足建筑户型无柱大空间设计要求且具有优良的力学性能和经济性指标,在设计中主、次结构连接推荐采用铰接连接。研究结果可为巨型钢框架-双钢板组合剪力墙结构的设计提供参考。
A mega steel frame-double skin composite shear wall residential system was proposed based on the mega structural system.A 156 m high calculation model was built based on a practical super high-rise concrete residential project background.The mechanical properties of the structure were evaluated by the elastic response and the elasto-plastic time-history analysis.The impact of the connection type of primary and secondary structures was studied for the overall performance and key structural components by comparing the different connection assumptions.Using the ABAQUS software,the influence of different connection modes between the secondary structure and the double skin composite shear wall on the components of the shear wall was analyzed.Finally,the economy of the new structural system was analyzed.The results show that the structural system can meet the design requirements of large space without columns in building units and has excellent mechanical properties and economic indices.Hinged connection is recommended for primary and secondary structure connection in design.The results may provide a useful reference for the designers.
