Abstract:
Unreinforced masonry structure is one of the most popularly used
constructions in the world, especially in developing countries. It is also unfortunately, the
most vulnerable to the earthquake. In this research, we conducted a series of experiments
to verify the suitability of PP-band retrofitting for masonry structures made of shapeless
stones. Material tests were conducted to understand the basic parameters of stone
masonry, i.e. shear, tension and compression strength. After the material tests, diagonal
compression test and out-of-plane test were carried out using masonry wallette made of
shapeless stones with and without retrofitting. From both test results, it was clear that
PP-band retrofitting improved drastically the overall stability and ductility of stone
masonry structures made of shapeless stones
