Experimental research on mechanical behavior of inclined steel tube confined concrete column-ring beam joint with shear ring bars;

In this paper,through direct shear tests on 3 steel tube confined concrete column ring beam joints with shear ring,the ultimate capacity,the mechanical mechanism,the sliding of ring beam relative to steel tube and the ultimate failure mode of ring beam were analyzed.

In this article,authors introduce a new steel pipe concrete ring beam joint,and compare its advantages and disadvantages with those of joints listed in current steel pipe column standard,and state some aspects of this joint such as structures,construction methods and its project application situation.

The joint,called ring beam joint,has been used in the project of Cui?hu Villa in Guangzhou.

Experiment and theoretical study on joint shearing capacity of the color steel sandwich panels filled with rock wool;
