Abstract:
Masonry buildings form significant part of the cultural heritage in the world. One of most important aspects for old and historical buildings is the vulnerability to lateral loads such as earthquake and wind loads and the need for appropriate strengthening. Fiber reinforced polymer (FRP) composite materials are developed options for strengthening of masonry buildings. The application of FRP composites as externally bonded reinforcement in repairing and strengthening the masonry walls has becoming more attractive than the traditional methods which are based on steel elements. Their excellent strength-to-weight ratio, easy installation and minimized damage for the existing structure made them the best option for strengthening of listed buildings and structures. In this research, an experimental study has been conducted to show the out-of-plane behavior of FRP strengthened large-scale masonry walls. The wall panels made of clay bricks have been investigated and the effectiveness of different type of FRP elements used for strengthening is analyzed.
