Earthquake Safety Analysis of an Historical Masonry Building

Abstract

In this study, how to study the earthquake safety of an Historical Masonry Residence that has wall damages because of soil sitting is shown. Restitution and restoration projects of the building are used in the analysis in addition to the site observation and research. The building has a basement, a ground floor, a normal floor and a half roof floor. The all walls of the basement and the outer walls of the other floors are made of stones. Inner walls are wood members. Stresses at the structural members are calculated by SAP2000 v.15 program. Planar stress analysis is made by SAP2000 v.15 program for ultimate loads. Structural members of building are modeled as shell member after the material properties are determined. Sittings of the building are considered as support settlement in the analysis. It is seen that most of the calculated stresses are lower than the limit stresses given in Turkish Seismic Code and only the basement walls have high stresses. These walls is strengthened by using FRP. Seismic behavior of residence is enhanced to demanded level by TSC-2007 with proposed strengthening method
