配筋混凝土轴向拉伸试验条件下的应力-应变关系研究
Study of Stress-strain Relationship of Reinforced Concrete under Axial Tensile Test
摘要
Abstract
Concrete stress-strain curve is an important parameter of concrete component bearing capacity,deformation analysis and crack research.In this paper,reinforced concrete specimens were designed and produced to carry out the tensile test of reinforced concrete specimens,so as to get the concrete axial tensile complete Stress-Strain curve in different reinforcement ratios by separating loads between steel and concrete,the axial tensile stress-strain curves of concrete under different reinforcement ratios,and then the corresponding stress-strain curve equation is obtained by piecewise fitting.Meanwhile,the influence of reinforcement ratio on axial tensile stress-strain curve of concrete is discussed.关键词
