介绍了某城市综合体商业中心的结构设计。针对该项目的超长结构不设缝要求,进行了温度内力计算,其中考虑了混凝土收缩的当量温差以及混凝土的徐变效应;同时,还提出了设计和施工阶段的构造措施,以保证结构安全。对大跨度连廊及长悬挑区域,采用实际人流步行时程荷载,计算了结构的加速度时程反应。 The structural design of a city complex commercial center is introduced. In view of the long structure of the project without any seam requirements, the calculation of temperature and internal forces was carried out. The equivalent temperature difference of concrete shrinkage and creep effect of concrete were taken into account. At the same time, the design measures and construction measures were also proposed to ensure the structural safety . For long-span corridors and long cantilevered areas, the time-history load of walking is used to calculate the acceleration response of the structure.
