Experimental Study on Masonry Wallette Made of Shapeless Stones Retrofitted by PP-band Mesh

Abstract

   Unreinforced masonry structure, typical non-engineered structure, is one of the most popularly used constructions in the world. It is also unfortunately, the most vulnerable to the earthquakes. In this research we conducted a series of experiments to verify the suitability of PP-band (Polypropylene band) retrofitting for masonry made of shapeless stones. PP-band is commonly used for packing and it is available all over the world at very low price. To understand the basic property and the effect of PP-band retrofitting method, material tests consist of shear, tension, compression tests, and diagonal compression and out-of-plane tests were carried out using masonry wallettes made of shapeless stones with and without retrofitting. Based on the experimental results, it was found that PP-band retrofitting improved the overall stability and ductility of the stone masonry structure. [This abstract is not included in the PDF]
