ABSTRACT

We subjected nine full-scale masonry infilled reinforced concrete frame specimens to quasi-static cyclic loading to critically review the methods for determining the damage state of masonry infill walls to develop reliable in-plane fragility functions. Among the three methods, the method based on maximum crack widths gave the smallest dispersion, whereas the skeleton curve-based methods generated excessive dispersions and the phenomena-based method was shown to be self-contradictory in certain circumstances. If the damage states were determined by maximum crack widths, neither the brick type nor the plaster had a significant influence on the fragility functions.

摘要

我们对九个全尺寸砌体填充钢筋混凝土框架试样进行准静态循环加载，以批判性地审查确定砌体填充墙损伤状态的方法，以开发可靠的面内脆性函数。在这三种方法中，基于最大裂纹宽度的方法的离散度最小，而基于骨架曲线的方法产生了过度的离散度，而基于现象的方法在某些情况下被证明是自相矛盾的。如果破坏状态由最大裂缝宽度决定，砖的类型和灰泥对脆性功能都没有显着影响。
