Description

An experimental program is underway at the University of Saskatchewan to investigate the performance of concrete masonry block walls reinforced with non-prestressed, unbonded reinforcement that are subjected to out-of-plane lateral loads. By eliminating the need for grouting, this construction method may lead to substantially lower wall weights, as well reduced construction times, cost, and workplace injuries. At the same time, the presence of reinforcement will increase the flexural strength of the walls, significantly increasing the allowable vertical spans of such walls as compared to those of comparable unreinforced walls. Unreinforced walls, as well as conventionally reinforced and partially grouted walls, were included in the experimental program to serve as control specimens against which the performance of the walls with unbonded, ungrouted reinforcement could be compared. Although the experimental program is ongoing, preliminary results described herein comparing the unbonded reinforced walls to unreinforced companion specimens suggest that this construction method is a promising alternative to more conventional systems.
