Abstract

Abstract

Based on the Unified Standard for Reliability Design of Building Structures (GB 50068—2018), the reliability of shear bearing capacity design formulas in the Technical Standard For Steel Reinforced Concrete Structures With Specially-Shaped Columns (T/CSCS 014—2021) was examined by taking the reliability of shear bearing capacity of solid-web steel-reinforced concrete special-shaped columns as the research object. Relying on the MATLAB calculation platform, calculation programs for the JC method and Monte Carlo simulation method were prepared respectively. On this basis, the effects of random variables—such as shear-span-ratio, concrete strength grade, hoop strength, section steel strength, axial compression ratio, load effect ratio, and live load type—on the reliability index of shear bearing capacity of solid-web steel-reinforced concrete special-shaped columns were analyzed. The performance of the target calculation formula was also evaluated. The results showed that under most working conditions, the reliability index of shear bearing capacity of solid-web steel-reinforced concrete special-shaped columns—calculated based on the load partial factors specified in GB 50068—2018—met the requirements but was conservative. It is suggested that the partial factor for constant loads should be adjusted to 1.2 to balance both reliability and economic benefits.
