Experimental Study on Structure Model with Shear Wall and Base Isolator Under Dynamic Forces

Abstract: The dynamic behaviour of structures is influenced by their fundamental frequency and the level of damping exhibited by each mode of vibration. The fundamental frequencies of a building significantly affect its response under dynamic load. Experimental studies can be conducted to predict the actual behavior of real structures, which have the advantage of explaining theoretical concepts and calibrating analytical models. In this study, an experimental investigation was conducted on a 3-story and 4-story aluminum building model with symmetric configurations. The model was subjected to harmonic and seismic excitation using a servo shake table to evaluate the different responses such as displacement of the Shear wall and base isolator. The software was also used to perform time history response analysis and compare the results with those obtained from the shake table. The experimental results showed that the structural responses could be minimized using the Shear wall and base isolator.
