Stability Analysis Of Single And Double Steel Girders During Construction, Sean Justin Coffelt
Stability Analysis Of Single And Double Steel Girders During Construction, Sean Justin Coffelt
Masters Theses
Built-up steel I-girders are very commonly used in bridge construction. Their spans are typically very long, and they are susceptible to lateral torsional buckling if not enough lateral support is provided. This thesis includes guidelines for preventing lateral torsional buckling of steel I-girders under dead and wind load, accompanied with finite element analysis of double girder systems. The first portion includes capacity envelopes for single girders with single and double symmetric cross sections under various loading conditions and boundary conditions for double and single symmetric cross sections with double girders subjected to dead loads only. The second portion is dedicated …
