Abstract:
Seven large-scale high-strength concrete (HSC) shearwall specimens named HSCW1 to HSCW7 were built and loaded to failure under inplane constant axial load and increasing horizontal loads. The test specimens were approximately 1/3 scale of a prototype wall. The compressive strength of concrete varied from approximately 11.6 ksi (80 MPa) to more than 14.5 ksi (100 MPa) for different specimens.
Except for Specimen HSCW4, which was tested under a very high compressive stress of approximately 2.9 ksi (20 MPa), axial compressive stresses of approximately 1.2 ksi (8 MPa), 0.6 ksi (4 MPa), and zero were applied to the specimens. The horizontal reinforcement ratios of 0.47 and 0.75% and vertical reinforcement ratios of 0.75 and 1.26% were chosen for the wall panels.
The experimental results of walls tested in this research as well as those reported by other researchers are compared with the ultimate resistance predicted by an interactive event simulator developed by the first author as well as the design procedures given in the Australian Standard AS3600 and ACI 318.
