Study on Displacement Ductility Coefficient of Steel Reinforced High-Strength Concrete Column

Abstract

In order to study the displacement ductility coefficient of steel reinforced high-strength concrete column, 23 groups of components with various design parameters were tested and related factors that affect the displacement ductility coefficient of SRHSC column were presented in this paper. The proposed formula for calculating the displacement ductility coefficient of SRHSC column can be obtained from the multivariate nonlinear regression of test results by using SPSS. The calculation results agree well with the test conclusions, and it shown that the proposed formulas own high accurateness and can be objectively reflect the mechanical behavior of SRHSC column root. The research achievements will provide a theoretical support for the design of SRHSC column.
