SEISMIC EVALUATION OF SINGLE-STORY REGULAR AND IRREGULAR BRICKS HOUSES IN IRAQ

Abstract

he seismic performance of the unreinforced brick houses building in Iraq was assessed in the present work considering of three types of the typologies. These houses are a kind of different types of masonry construction for houses in Iraqi cities, where bricks are used with cement mortar in the construction of these houses. The main aim of work herein is the study of the seismic sensitivity of three types of single-story houses in two perpendicular directions (x- and z- directions), by using the nonlinear dynamic analysis (Time-History analysis) in ABAQUS software. The houses were analyzed in two cases (regular and irregular in plan) while the height was constant for all models (3m). From the results, it can be concluded that the dimensions of these houses buildings, for all case studies, are the strong influence on the values of the ultimate top displacement and the ultimate base shear. Where the values are greater when placing the seismic wave in the largest direction and vice versa. The general trend of changing in these values occurs when changing the direction of the seismic wave.
