深圳宝城1#楼为高层商住楼,采用框支剪力墙结构体系,由于平面凹凸不规则、扭转不规则及竖向构件间断,属于超限高层结构。采用PKPM和ETABS软件进行多遇地震和设防地震的弹性计算,采用MIDAS软件进行罕遇地震静力弹塑性分析。对剪力墙竖向不连续和转换层楼板进行重点分析;对整个结构的薄弱部位,通过提高剪力墙抗弯承载力和延性来改善结构抗震性能。综合分析结果,提出了超限设计措施,并有针对性地采取了构造加强措施。
Shenzhen Bao City, 1 # floor for high-rise commercial and residential buildings, the use of frame-supported shear wall structure system, due to irregular convex irregularities, irregular torsion and vertical components, are overrun high-rise structure. The elastic calculation of earthquakes and fortified earthquakes with PKPM and ETABS software is carried out. The static elasto-plastic analysis of rare earthquakes is carried out by using MIDAS software. The vertical discontinuity of the shear wall and the floor of the conversion floor are analyzed emphatically. For the weak parts of the whole structure, the seismic performance of the structure is improved by increasing the flexural capacity and ductility of the shear wall. According to the result of the comprehensive analysis, the overrun design measures are put forward and the measures of structural reinforcement are taken.
