Rehabilitation of Cracked RC-Brick Masonry Wall with Opening by BFRP Composite Material

Abstract:

This in-plane behavior of two one-half scale reinforced concrete (RC)-brick masonry walls with opening before and after retrofitting with basalt fiber reinforced polymer (BFRP) is investigated. One specimen was served as the reference without any strengthening scheme; another one was first tested to the severely damaged level, and then retrofitted with BFRP in a mixed strengthening configuration on two sides. Both of these specimens were tested under in-plane constant vertical load and cyclic lateral load. Test results are analyzed in terms of failure mode, maximum shear strength, ultimate drift, energy dissipation and equivalent viscous damping coefficient, which indicated that the use of BFRP composite material can effectively improve both the strength and deformation capacity of the damaged masonry wall as well as changing failure mode and maintaining the wall’s integrity.
