N2 - Recent research findings indicate that high-strength concrete (HSC) can lead to new seismic design possibilities by allowing the incorporation of ductile shear failures as a new genre of ductile failure mechanisms. This paper reports research aimed at proving the noted hypothesis for HSC structural walls. Eight 1/5-scale thin-webbed walls with well-confined boundary elements and an aspect ratio of 2.5 were tested with design concrete compressive strengths of 34, 69, 103, and 138 MPa (5, 10, 15 and 20 ksi) under in-plane monotonic and cyclic loading. Results have proven that the use of HSC can enhance system ductility of structural walls by increasing web crushing shear capacity and thus allowing the development of stable inelastic flexural response. The enhancement, however, was found to be dependent on damage accumulation and thus limited to varying degrees by the damage tolerance of HSC. Preliminary findings on establishing the limits to inelastic web crushing are discussed.
