现代化的综合楼,集多项使用功能为一身,特别是建筑物大多设有大面积裙房、地下室车库。建筑功能要求的特殊性和施工工艺的局限性,决定了用沉降缝将主楼与裙房分为若干独立结构的做法难以满足建筑功能要求。如果主楼与裙房间能不设沉降缝,上述问题便迎刃而解了。但由于主楼与裙房两者间荷重相差悬殊,因而会产生过大的差异沉降及较大的次应力,导致结构产生裂缝甚至破坏。另
The modern comprehensive building integrates many functions. In particular, most buildings have large-scale podiums and basement garages. The particularity of the architectural function requirements and the limitations of the construction process have determined that it is difficult to meet the architectural function requirements by dividing the main building and the podium into a number of independent structures using settlement joints. If the main building and the skirt room do not have settlement joints, the above problems will be solved. However, due to the great difference in load between the main building and the podium, it will produce excessive differential settlement and large secondary stress, leading to cracks and even damage to the structure. another
