Understanding Buckling Behavior and Using FE in Design of Steel Bridges

摘要

This paper describes how Finite Element (FE) analysis can be used to predict buckling modes,highlighting methods which are practical for day-to-day use. It explores some criterion which might be used toidentify if such behavior, including global buckling modes, should be of concern to the designer, drawing onrecommendations including those in the recently published NCHRP Report 725 and Eurocodes. Use of FE in thedetermination of member resistances is also explored.
