A Critical Review of Methods for Determining the Damage States for the In-plane Fragility of Masonry Infill Walls

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.
