Seismic Vulnerability Function for Masonry Buildings Considering the Variability of Materials

Abstract eng:
This paper proposes a methodology and an equation to determine the vulnerability of masonry structures taking into account the variability of mechanical properties due to lack of supervision during its construction in terms of three important parameters: the type of mortar defined by its resistance, the thickness of joints between bricks and the concrete strength on confinement beams and columns. The proposed expression is based on the statistical treatment of results obtained from carrying out Incremental Dynamic Analysis (IDA) using a set of seismic records for common structures built in the country. With the proposed expression the estimation of expected damage on masonry buildings under seismic actions will be more accurate.
