Study on the Mechanical Properties of Grouting-sleeve Reinforcementconnection Component under the Action of Cyclic Tension Load

摘要

By means of finite element software ABAQUS, the numerical model of grouting-sleeve reinforcement-connection component under the action of axial load was established. Two kinds of loading system were considered, one was axial tension load with constant loading rate, and another was unidirectional cyclic load. The latter loading system simulates frequent earthquake action. The stress distribution of grouting-sleeve reinforcement-connection component in accordance with two kinds of loading system was calculated, as well as the compressive stress variation of grouting-material was studied, which provides the reference for further research on the mechanical properties of grouting-sleeve reinforcement-connection components.
