摘要

In this paper, the effect of mid-connection detail of cross bracings comprised of build-up sectionson the elastic-plastic behavior of braced systems is investigated. Then, a proposed symmetricmid-connection detail is compared with the commonly used one, analytically. In common midconnectiondetail of cross-braces with build-up sections, one diagonal member (which iscomprised of a pair of channels or angles) is usually discontinuous at the mid-connection and theother diagonal member is continuously passed through the connection. A rectangular gusset plateis used to join the discontinuous and continuous diagonals, in practice. In the proposed methodone section from each diagonal member is discontinuous and the other is continuous and thiscauses both the diagonals to be semi-continuous at the center connection.Buckling and post-buckling behavior of single span-single story models of cross-bracingsystems, have been studied during a linear and nonlinear static finite element analysis. Theresults show that the proposed mid-connection detail can improve both strength and ductility ofthe cross-braced systems.
