摘要：

This paper describes an experimental evaluation on the isolated and combined effects of high-strength concrete and high-strength steel on the behavior of stocky reinforced concrete structures. Monotonic lateral load tests were conducted on four cantilever deep beam specimens, which represented slices along the length of a prototype stocky shear wall without boundary regions/members. The specimen using both high-strength steel and high-strength concrete resulted in the greatest lateral strength and deformation capacity, demonstrating the benefits of high-strength concrete when using high-strength steel in stocky structures. Inadequacies in code-based predictions were observed for peak wall lateral strength and stiffness, pointing to the need to reassess the current design provisions for stocky walls.
