Assessment and performance based strengthening of an original composite material designed building

Abstract

A 100 years old historical building constructed with an original composite material was assessed. Even though the compressive strength of the material was found to be relatively high, the structure was found weak for carrying the static and lateral loads. Performance – based seismic retrofitting was carried out. A solution was proposed to strengthen the structure in order to withstand the level of hazard 2% in 50 years. The structure was modeled before and after the strengthening using inelastic dynamic time history analysis, and inelastic static pushover analysis. Results and comparisons of modeling are given before and after strengthening.
