Effective Length Factor for Discontinuous X-Bracing Systems

Effect of mid-connection detail on the behavior of x-bracing systems

“…So the results of the extensive finite element analyses of the models reasonably confirm the previous results obtained from the elementary beam-column theory [13].…”

“…The effective length factor of cross-bracing members is affected not just by the end conditions of the members at the corners, but even by the conditions at the mid-span connection [13]. For a cross-bracing consisting of build-up sections with a gusset plate at mid-connection, it was revealed that detail of the connection at intersection point could affect effective length factor of the members in out-of-plane buckling; Thereby a more proper detail was proposed.…”

An efficient and direct method for out-of-plane buckling analysis of Y-braced steel frames

“…1. Also the length of bracings members can be determined as follows: (6) in which L i is the length of the ith member.…”

“…The closed-form solutions of X-bracing systems with a discontinuous diagonal are discussed in [6][7][8]. An iterative method of analysis has been developed to study the nonlinear load-deflection behavior of Y-bracing systems in [9].…”

Out-of-plane buckling and design of X-bracing systems with discontinuous diagonals

“…3 are called X-bracing systems with a discontinuous diagonal. Davaran [9] proposed the closed-form solutions of X-bracing systems with…”
