- Abstract
One of the mechanical key problems on concrete-filled steel tube (CFT) structure is the confining effect between the steel tube and the core concrete. The key technology to solve the problem is to accurately describe the interfacial mechanics properties. Based on continuum mechanics theory, by means of the solving method on plane problem in elasticity and structural mechanics displacement solution, using the function expression to describe the interfacial normal force distribution, a small-deformation elasticity analysis theory on the interfacial mechanics problem is framed for the CFT structure. The results show: The hooping force distribution in the interface between the core concrete and the steel tube is not uniform. The hooping force in the long side of rectangle is smaller than one in the short side of rectangle.
