Title: Behavior of Hooked Bars in Reinforced Masonry

Abstract:A limited study was conducted to examine the behavior and anchorage characteristics of a typical size of hooked reinforcing bar in a reinforced concrete masonry wall. The specimen configuration was intended to represent a portion of wall adjacent to an opening. The hooked bar was typical of either shear reinforcement or tension steel in a bond beam. The horizontal bar was hooked around the vertical steel (jamb reinforcement). Tension was applied to the vertical and horizontal steel, while relative displacements were observed as a function of the load. One specimen was instrumented with strain gages on the steel so that stress distribution in the steel and bond stress between the steel and the grout could be determined. Standard and nonstandard hook configurations were used. Both types of hooks provided sufficient anchorage to develop the steel to its capacity.
