Seismic risk reduction of unreinforced brick masonry buildings using Ferrocement overlay.

Byline: Mohammad Ashraf, Amjad Naseer, Mohammad Javed and Akhtar Naeem Khan

Ferrocement overlay is the surface application of steel wire mesh and plaster. The technique, which is low in cost and simple in application, may effectively be used to increase the vertical and lateral load carrying capacities of unreinforced masonry that results in reduction of seismic risk. This article presents a state-of-the-art review on ferrocement overlay and its application to unreinforced masonry buildings in Pakistan to reduce seismic risk. Various experimental tests performed on application of ferrocement overlay to local masonry have been discussed. Based on these test, it is concluded that ferrocement overlay increases the seismic capacity of single and double unreinforced masonry buildings in Pakistan by two times and thus substantially reduces the seismic risk.
