摘要
针对框架结构中底层空心砌块填充墙严重开裂现象,采用ANSYS程序建立三维有限元模型、进行了墙体荷载作用下结构有限元分析,通过墙体应力分布与墙体裂缝形态的对比,分析了框架结构中底层空心砌块填充墙中裂缝的成因,最后提出了相应的裂缝防治建议。
Resulted from the surface of hollow block filling wall fractured severely in first floor of frame, the finite element soft- ware ANSYS has been used to developed a 3-D model under vertical load due to the weight of filling wall,and make a finite element analysis, the stress distribution in filling wall has been determined, which is compared with the crack distribution patterns of filling wall, and crack origin of hollow block filling wall in first floor of frame is analysed. At last corresponding prevention measures are also proposed.
