Seismic Resistance of Unreinforced Brick Masonry Buildings: An Experimental Study

Abstract:

This paper presents a study on seismic resistance of typical single and double storey masonry buildings constructed in the southern districts of Pakhthunkhwa, Pakistan. Two types of bricks; wooden and rice husk burnt bricks, have been investigated in combination with mud and cement-sand mortar. Plane and reinforced specimens have been tested in axial compression and diagonal compression. Analysis of the experimental results show that both single and double storey buildings constructed in the study area with mud mortar and mud plaster are seismically vulnerable. However application of the wire mesh on wall surface subsequently plastered increases the strength significantly and make the structure resistant to the earthquake forces.
