【摘要】 目前,混凝土小型空心砌块被大量应用于框架填充墙中,因其收缩性较大,所引起的墙体裂缝问题越来越受关注,也影响着非黏土墙材的进一步推广。针对这一问题,利用有限元的方法对框架填充墙进行裂缝机理研究分析,得到单层单跨不同构造措施填充墙的裂缝的初始形成位置及其开展情况,比较了各种构造措施对框架填充墙抗裂性能的提高情况,最后结合分析结果对裂缝的控制提出了一些建议。更多还原

【Abstract】 At present small concrete block has been used popularly in infill panels of frame.Due to its dry shrinkage,attention has been paid to the problem of its wall cracking.With the aid of ANSYS,incipient crack and its developing direction in infill plane of single-frame with different structure measures were investigated and then the cracking mechanism was obtained.Comparison of efficiency among above single-frames was done.At last,some preventative measures against wall cracking were proposed.更多还原
