The thin reinforced concrete walls present the problem of reinforcement congestion that usually leads to the formation of voids and segregation of the concrete. To control the problem described, it was considered the possibility of replacing the conventional bars mesh located at the central part of the wall for polypropylene and metallic fiber. To verify the hypothesis, tests were conducted of cyclic lateral loading applied to shear walls with the three types of reinforcement indicated, while ductile bending reinforcement remained constant.
