Research Status of Concrete Strength Theory Based on Stress and Strain

Abstract:

In the civil engineering structures, when concrete structure withstand external loads, internal defects such as micro-cracks gradually developed, eventually will lead to the destruction of the concrete. Currently, there are two types of strength failure criterion of concrete, strength failure criterion based on stress-space and strength failure criterion based on strain-space, both of which have advantages and disadvantages, this paper introduces the research status of the two strength failure criteria of concrete, and the problems need further study in the future. It plays a strong practical significance in scientific research.
