Seismic retrofitting of reinforced concrete frames with masonry infill pannels

Abstract

The experimental and numerical research as well as the observations performed in areas affected by earthquakes contribute new data about the seismic behaviour of buildings. The advances in this field produce more demanding codes and more effective construction systems. One of the main objectives of seismic engineering is to find simplified methods of assesment of the potential damage in a structure under earthquake loadings as a measure of the repairability of the structure. In the present work a seismic retrofitting technique is proposed for masonry infilled reinforced concrete frames. The performance of this technique is evaluated through experimental tests. In the same way, a simplified numerical model for structural damage evaluation is proposed and calibrated with the experimental results
