Ring Type Stirrups Welded High-strength Concrete Columns Experimental Study of Large Eccentric

This experiment is researched through three welding ring type stirrups high-strength concrete columns of large eccentric.High-strength stirrups are used by HRB400 steel.Its mechanical properties are researched;the bearing capacity of the great eccentric compression can be greatly improved through the experimental researches.And the bearing capacity analysis of the root causes is improved in theory,however,the changes of the column has been analyzed in ductility.High-strength concrete is in the compression of three-edge state,it makes the concrete confined concrete,and so the problem that the bearing capacity of large eccentric columns is difficult to effectively improve can be solved.
