Seismic Performance of Reinforced and Unreinforced Masonry Brick Walls Assembled With Head-Straight Texture Order


Abstract eng:
As we know there are different types of texture order for brick arrangement in construction of brick walls. Among these methods, the one which is very customary, known as head-straight texture order. In process of construction using this technique because of special arrangement of masonry units, some regular interval voids appear over the height of the wall. In this study through filling the holes using steel fiber concrete, we tried to study the roles of these regular slim concrete columns on seismic performance and failure modes of masonry walls. For this purpose four specimens with different level of pre-compression vertical load, have been designed and cyclic loading test were carried out according to evaluate in-plane shear behavior and identification of shear strength, ductility and stiffness degradation of aforementioned panels. Four specimens are two panels without concrete cores and two panels with fiber concrete cores. The results showed that all the specimens failed due to development of horizontal cracks from sides to the middle in the first layer from the bottom of the specimen. Comparisons were made along the results of seismic analysis of two types of masonry panels. The results evidence that existing of fiber concrete columns despite having positive effect on the shear resistance of the walls, causes significant influence of the seismic performance such as ductility.
