Abstract
Experimental investigations to evaluate seismic performance of the masonry models constructed using Compressed Stabilized Earth Block (CSEB) and Modified Compressed Stabilized Earth Block (MCSEB) manufactured from locally available soil, were carried out on four reduced models that represent normal single room building. Two models of different blocks were constructed with earthquake resisting features [EQRF] having sill band, lintel band and vertical bands to control the building vibration and another two were without EQRF. To study the behaviour under seismic load, models were placed on shake table and subjected to long-period ground motion by large amplitude by many cycles of repeated loading the test specimen were shaken repeatedly until the failure. The test results from Hi-end Data Acquisition system show that earthquake resistance of models with EQRF was better than models without EQRF more over MCSEB along with EQRF behave better than CSEB with EQRF
. This technology will definitely be an appropriate, cost and energy-efficient, and sustainable.
