Abstract

The research team studied a steel pipe grouting connection method with favorable application scenarios and mechanical properties. By installing three types of shear key—annular, parallel spiral and cross spiral—inside the steel pipe sleeve grouting connector, the problem of limited application of traditional connection methods was solved. Based on experimental research, finite element simulation and theoretical analysis, this paper summarizes relevant research results at home and abroad, verifies the feasibility of this connection method, and analyzes its mechanical advantages. It is concluded that this connection method is suitable for the complex stress requirements in multiple fields, with convenient construction and controllable cost, boasting broad engineering application prospects and providing technical support for the high-quality development of steel structures.
