Shear Behavior of Concrete Slabs Longitudinally Reinforced with High-Performance Steel

Using high-performance ASTM A1035 steel in concrete members can reduce life-cycle costs and improve durability. However, sectional shear design models must account for the higher expected reinforcement strains in order to efficiently use the strength of high-performance reinforcement in concrete slabs. This paper presents analytical and experimental results for six shear-critical slab strips longitudinally reinforced with high-performance steel conforming to the ASTM A1035 standard but without web reinforcement. Overall heights up to 600 mm (23.6 in.) and a constant shear span-depth ratio of 3.5 were used. The influence on shear capacity from the longitudinal steel reinforcement ratio, nonlinear response of the steel, and the member depth are investigated. The load-deflection response, ultimate load-carrying capacity, and mode of failure were of primary interest. The test results and other published data were compared against capacity predictions using several analytical and numerical shear design models. Improved predictions were obtained from models that could account for the influence of reinforcement strains and member depth on shear capacity. A simplified shear design model was developed for use in combination with a previously developed flexural design model for slabs longitudinally reinforced with ASTM A1035 steel.
