Application of 3D Micro Models for Seismic Resistance Forecast of Framed-Masonry Structures : Preliminary Activities

Framed-masonry composites present the classical construction approach used in many earthquake prone countries worldwide. Unfortunately, the seismic resistance forecast of such structures remains difficult. One of the most important reasons for that is the lack of the appropriate material model that takes into account the orthotropic properties of the masonry wall and/or units such as hollow clay masonry units. A problem that extends on the previous is the high variation of the material properties of the masonry wall and its constituents. Therefore, this study is focused on the influence of the various strength deviations on the critical stress and strain outcome when hollow clay masonry units are used. We build spatial micro models of masonry walls and tested them under vertical and horizontal compression. The results have shown that the influence of the variation of masonry constituent properties is not negligible, which may significantly alter the stress and strain response of the structure.
