本研究以韩国学校建筑混凝土砌块填充钢筋混凝土框架为研究对象，在循环荷载作用下进行试验，并提出简化模型，研究混凝土砌块墙体残余裂缝宽度与框架残余变形之间的关系。虽然混凝土砌块墙体的实测裂缝宽度远小于残余变形，但本文提出的考虑柱的弯剪变形分布的简化模型可以合理地再现实测裂缝宽度。进一步研究了混凝土砌块墙体裂缝宽度与框架残余变形的关系，发现两者之比约在0.2 ~ 0.3之间。这一结果表明，框架的残余变形可以通过混凝土砌块墙体的裂缝宽度来估计。
In this study, concrete block infilled reinforced concrete frames for school buildings in Korea are tested under cyclic loadings, and a simplified model is proposed to investigate the relationship between residual crack widths in concrete block wall and frame’s residual deformations. Although the measured crack widths in concrete block walls are much smaller than the residual deformations, a simplified model proposed in this paper considering flexural and shear deformation distribution of columns can rationally reproduce the measured crack widths. The relationship between crack widths in concrete block wall and frame’s residual deformations is further investigated and their ratio is found to lie approximately in the range of 0.2 to 0.3. This result implies that the residual deformation of frames can be estimated form crack widths in concrete block wall.
