Innovative Technology For the Reinforcements of the Columns and Shear-Walls
During the construction of rectangular reinforced concrete structural walls, it is required, in most cases, to install
closely spaced stirrups around the dense longitudinal reinforcements at the boundary regions of structural walls. High
percentage of steel is needed at the end regions of the walls and limited dimensions of the elements cause extensive problems
during construction and placing of the boundary reinforcements. This leads to errors in construction of the reinforced
concrete structural wall reinforcements and in most cases may make the construction impossible. To overwhelm this
difficulties, prefabricated composite shear walls (PCSW) having L profiles and L section folded plates (L shape steel made-
up sections) as longitudinal reinforcement and special stirrups in boundary regions was proposed. In the scope of the
experimental study, the proposed PCSW test specimen was tested under reversed cyclic lateral loading. The seismic behavior
PCSW test specimen was investigated by evaluating and interpreting the experimental results. The PCSW specimen showed
desirable flexural strength and deformation capacity.
