Increasing Strength and Ductility in Concrete Masonry Shear Walls Using Confinement
The study investigates the use of steel confinement techniques in concrete masonry to increase the strength and ductility of shear walls. Structural design moment and curvature equations are derived and studied for beam type and column type shear walls. Steel confining plates in the mortar bed joints, steel spirals in the unit cells around the rebars, and joint reinforcement are three identified methods that appear to be practical and potentially desirable from a ductility improvement perspective. The design parameters for unconfined and confined strain curves are identified for a general stress-strain equation. Moment curvature plots are presented for beam and column shear walls. A test program is described for improving confidence in the design equations, rating the ductility of the confining plate and joint reinforcement steel confinement options, and establishing numerical values for the design variables.
