Ageing Impact And Crack Study Of Unreinforced Brick Masonry Structure And ITS Remedy

Abstract

Unreinforced masonry (URM) buildings represent a large portion of the buildings stock around the world and in Bangladesh. During the construction of those buildings very little or no seismic design requirements are considered. Moreover, no dynamic test on unreinforced masonry building made by Bangladeshi indigenous material is done yet. Therefore, the objective of this study is to understand the Ageing impact and Crack study of the unreinforced masonry (URM) building of Bangladesh. In this study we visit the two sites in Old Dhaka and Narayanganj. In our visiting time we collect the different data for our thesis study. In the basis of collecting data we trying to analyzing different cracks and ageing impact of the unreinforced masonry structures. We also trying to find out causes of the cracks. After analyzing we found some specific causes of cracks. Basis of the finding results we trying to suggest the remedy or retrofits of those cracks whose are created by different causes. We also suggest prevention and repair of the ageing impact on unreinforced brick masonry structures. I sincerely hope that this document is an unpretentious but interesting contribution for the growing knowledge in the masonry field
