某8度区空旷体育建筑主体采用了钢-混凝土混合结构,下部混凝土结构采用框架-剪力墙结构,大跨屋盖采用钢结构网架结构。采用整体建模计算,对高震区的空旷体育建筑进行了结构分析和设计,探讨了空旷结构的抗震设计。空旷结构的抗震设计应从整体抗震概念上着手,利用有限元软件YJK,MIDAS/Gen进行抗震计算,并对计算结果进行人工调整。设计中需提高关键构件的抗震性能指标,加强其抗震构造措施。
An 8 degree area of open sports architecture using steel-concrete hybrid structure, the lower part of the concrete structure using frame-shear wall structure, long-span roof with steel structure. Using the overall modeling calculation, the structural analysis and design of the open sports building in the high earthquake area are carried out, and the aseismic design of the open structure is discussed. The aseismic design of open structures should start with the concept of overall earthquake resistance, use the finite element software YJK and MIDAS / Gen to carry out seismic calculation and adjust the calculation results manually. In the design, it is necessary to improve the seismic performance of the key components and to reinforce their seismic structures.
