Bonding property and seismic behavior of reinforced concrete and finite element analysis

Reinforced concrete is one of the most widely used building materials in civil engineering, water conservancy and hydropower engineering, and construction engineering; in the course of its service, due to human or natural factors, reinforced concrete structures will gradually age, or be damaged or even destroyed. Therefore, in order to evaluate the durability of reinforced concrete structures, it is necessary and meaningful to study the problems of bonding and seismic performance. Based on the separation model and nonlinear constitutive relation, the finite element model of reinforced concrete beam specimens is established by using large-scale general finite element simulation software ANSYS. The corrosion rate, failure morphology, bond strength, and stress of steel bars are analyzed. The influence of slippage on the bonding properties of the test piece, and the effects of axial compression ratio, steel reinforcement ratio, steel bar strength, concrete strength, etc., on the seismic performance of the test piece were studied, in order to further utilize ANSYS on the bonding and resistance of reinforced concrete. A comprehensive study of performance provides a reference.
