- An analytical study on the cyclic behavior of double-tube type buckling-restrained braces
Abstract
This study is aimed at investigating the cyclic behavior of buckling-restrained brace (BRB) members of double-tube type. At first, an analytical model for simulating the cyclic behavior of double-tube type BRB is developed. Then a parametric study is carried out for verifying the effect of local buckling occurring in the core (inner) tube. As a result, it is found that local buckling greatly affects the cyclic capacity of double-tube type BRB. Moreover, the cyclic demand for double tube type BRB can be predicted using the radius-thickness ratio parameter.
