摘要

结构为大跨度连体结构,位于8度区。结构设计中结合建筑功能使用要求确定了连体桁架部位的结构方案。对整体结构采用性能化设计,整体抗震性能目标为D级。其中,连体桁架及其支座、剪力墙底部加强区采用中震弹性、大震不屈服控制,剪力墙与型钢柱采用中震不屈服控制。对小震采用反应谱分析和弹性时程分析,对中震进行承载力复核以及对大震采用弹塑性动力时程分析,并对大震下的连体结构楼板进行应力分析,结果满足规范要求。
        This structure is the large span connected structure located in the 8 degree area.In this structural design,the structural concept of the connecting truss was determined by using requirement of building function The structure was designed by performance,the connecting truss and its support,the bottorn of shear wall strengthing zone were controlled by elastically in middle earthquake,unyieldingly in rarely occurred earthquake.Shear wall and steel column is controlled by unyieldingly in middle earthquake.Small earthquake,middle earthquake and rarely occurred earthquake was analyzed through response spectrum analysis,elastic time history analysis and elastic-plastic dynamic time history analysis respectively.Stress analysis of the structural floor slab was made under the rarely occurred earthquake.The results meet the requirements of specification.
