Masonry Wall Crack Control with Carbon Fiber Reinforced Polymer
Publication: Journal of Composites for Construction
Volume 9, Issue 1
Abstract
Restrained shrinkage is a major source of damage to buildings. By the combination of different construction materials, or through different conditions of exposure of different structural elements, differential dimensional change occurs. Thereby, stresses arise, which can cause cracking. In recent combined experimental and numerical research projects, this source of damage to masonry walls has been confirmed. The ability has been developed to predict the level of damage computationally. This paper addresses a method to reduce the width of cracks in masonry walls subjected to restrained shrinkage, to acceptable levels. Crack control by externally applied carbon fiber reinforced polymer (CFRP) reinforcement is studied. Although structural strengthening by CFRP reinforcement is actively researched, its application here to preserve structural serviceability is novel. An experiment was designed and performed to study the response of an unreinforced masonry wall to restrained shrinkage. Subsequently, the wall was repaired and reinforced on one face with CFRP strips. The required CFRP reinforcement was designed by finite element analysis, which also served as prediction of the response of the reinforced wall to restrained shrinkage.
