Practical Methodology for Improving Seismic Performance of Masonry Buildings in Mexican Towns

Abstract eng:
In order to evaluate the structural vulnerability of masonry buildings on the basis of an earthquake disaster mitigation program, in this work a density of walls (DW) curve for Southern Mexican cities is proposed. A special methodology to compare the results with those obtained by 3D FEM models is also shown. Results shown that high damage can result on most of the studied cases as actual DW values for buildings in the shorter direction are extremely low. In order to avoid an inadequate structural behaviour, simple strategies as well as low cost retoffiting recommendations based on the obtained DW curve are proposed.
