Study on shear capacity of ultra-high performance concrete squat shear walls

Ultra-high performance concrete (UHPC) is a new building material with great application prospects in the engineering field. The material’s advantages include high strength and good durability, which can reduce the cross-sectional area of members and the weight of the structure. In order to study the shear capacity of a UHPC squat shear wall, a low-cycle repeated load test was carried out on a specimen with a height-to-width ratio of 1.0. Shear failure of the specimen occurred, and the cracks were widely distributed. A large cracking load and bearing capacity were achieved, and the specimen's deformation performance met the current code’s requirements. Based on the test results, formulas for calculating the cracking load and shear bearing capacity are proposed for a UHPC shear wall with an inclined section. A comparison of the calculated and measured results indicates that the proposed formulas reflect the test results well, enabling their use in engineering applications.
