某青少年活动中心超长结构温度裂缝问题的解决方法

Resolve method of super-long structure on the temperature crack problem of the Youth Activity Center

某青少年活动中心地上6层,地下1层,主体结构平面投影长度为182m,投影宽度为66m,现浇钢筋混凝土框架结构。为解决温度作用对结构的不利影响,同时又不影响建筑整体效果,经分析研究,设计时将1层到5层楼板平面设置两道温度变形缝,第6层顶板与屋盖结构连续,变形缝宽度能满足温度作用下结构变形需要,屋顶整体连续板的设置有效连接与协调了1层至5层三个独立结构单元,确保结构的抗震性能。

The Youth Activity Center is the cast-in-place reinforced concrete frame structure,which is 6 floors on the ground,1 layer on underground,182 meters plane projection length of the main body,and 66 meters projected width.To solve the adverse effect of temperature on structure and without affecting the overall effect of the building,through analysis and research,two temperature deformation joints are arranged in the plane of one to five floors in the design.The roof structure of the sixth floor is continuous,and the width of the deformation joint can meet the deformation needs of the structure under the action of temperature.The arrangement of the whole roof continuous slab effectively connects and coordinates three independent structural units from one to five stories to ensure the seismic performance of the structure.
