Abstract:
Most residential structures in developing countries are masonry structures
which are highly vulnerable to earthquake and increase the structural damage and the
death toll. This paper discusses the seismic capacity of non-engineered common masonry
structures in Pakistan, which having more tendency to collapse due large weight of slab,
by experimental approach using 1/12 miniature models. These models were constructed
using acryl blocks which can be used several times. This paper also includes the
comparison of retrofitted masonry model by PP-band, a method proposed by Meguro
Laboratory, IIS, the University of Tokyo, with non-retrofitted one. The PP-band
retrofitted masonry model showed almost 4 and 16 times greater seismic capacity than
the non-retrofitted one in terms of ground acceleration and arias intensity, respectively.
