Shear Strength of Reinforced Concrete Walls Subjected to Cyclic Loading
This research proposes a new shear strength model, based on modifications to the UCSD shear model by Kowalsky and Priestley [2000], to calculate the shear capacity and predict the displacement ductility of reinforced concrete walls in diagonal tension. An experimental database is created from a literature review of experimental tests of reinforced concrete walls that exhibit strength degradation and shear failure during cyclic loading. This experimental database is used in the formulation of the proposed shear model and to test the accuracy of the model. The proposed model improves the accuracy of calculating pre-emptive shear and flexure-shear strength, correctly identifies the failure mode for all collected specimens, and provides the closest prediction of the ultimate displacement ductility. Based on this research, the proposed shear model is recommended for the calculation of the shear strength of reinforced concrete walls for either the assessment of existing buildings or the design of new structures.
