Numerical Study on Strengthening of Brick Masonry Walls Using CFRP Strips
Structure constructed of brick masonry wall along with mud mortar has been used since long time in construction industry. It will get deteriorated due to various reasons and it is essential to find a method/material to strengthen it, since it is necessary to preserve values and culture of previous generation. Carbon fiber-reinforced polymer (CFRP) possesses essential properties and it has been tried and tested widely in structural repairs. The objective of the present study is to determine the effectiveness of using CFRP strips of varying thickness and width on enhancing load carrying capacity of brick masonry walls. Hence in the present numerical study, three sets of brick masonry wall models, each consisting of seven sample walls has been considered, modeled and strengthened using CFRP strips in various layouts. Increase in the thickness of strips had less impact on strength whereas increase in width of strips up to 240 mm provided considerable improvement in load resisting capacity of wall (up to 70%) along with reduction in strain in walls. Out of several layouts and dimensions of CFRP strips considered, combination of horizontal and vertical strips with thickness 3 mm and width 240 mm, respectively, is found to be more effective in terms of load resisting capacity and reduction in strain.
