Short summary

An iron sphere was applied to substitute of debris flow. Walls were constructed in prototype dimensions to physically simulate the damaged structures in debris flows. The quantitative estimation of the vulnerability of brick and concrete wall was established based on fuzzy mathematics and the proposed failure criterion. The results show that the maximum impact bending moment seems to be most suitable for the disaster intensity index in establishing vulnerability curve and formula.
