摘要
对工程实例中顶层墙体裂缝产生的原因进行了定性分析 ,指出设计上的失误导致墙体中存在较大温度应力 ,并根据实际结构形式对温度应力进行了定量分析 ,证明墙体中温度应力大大超过墙体抗剪设计强度 ;由该工程得到启示 ,设计人员应由具体结构形式和结构特点采取相应措施对温度应力进行抵抗或释放 ,以达到控制目的 .
The qualitative analysis is given to the reason of crack in the roof wall of an engineering example, and wrong in design is pointed out; The quantum analysis is also given to the temperatures tress,proving that temperature stress exceeds design shearing strength greatly. The illumination is gotten that the designer should take steps to resist or release temperature stress in order to attain the goal of controlling the temperature stress in structure design.
