Abstract

In this paper the traditional covering plaster of masonry buildings is supplied with Polypropylene and steel fiber to enhance their seismic behavior. The plaster mix proportion is determined by some initial mortar tests. Also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the specimens with the above types of mortar is evaluated. The specimen plastered with a traditional plaster was regarded as control and its earthquake behavior was compared to that reinforced by fiber plaster. Steel fiber or polypropylene addition significantly increased stiffness, displacement ability and energy consumption ability of specimens as compared to control. The suggested reinforcement method was proven to strengthen masonry buildings in a fast, reliable and economical way. Moreover, it can easily be adapted to any masonry building without causing any negative impact. The suggested method is fire and corrosion resistant.
