浅谈预应力混凝土梁腹板的斜裂缝
Aiming at the common occurrence of inclined cracks of cast-in-place concrete slab,this paper chiefly analyzes the 45 diagonal through cracks with an example in engineering practice,and applies the number analysis to calculate 1/8 places of biggest and main tensile stresses in the case of the shrink stress and temperature stress.
针对目前现浇楼板角部多出现斜裂缝的现象,结合工程实例对板角45°斜裂缝进行了着重分析,并采用解析分析计算收缩应变和温度应变以及在板角1/8跨范围的最大主拉应力,且指出墙体与楼板混凝土的收缩差以及二者之间的温差在楼板中所引起的温度收缩应力是板角开裂的主要原因,为工程实践提供理论依据。
