Influence of Closure Sequences on the Rigid Frame-Continuous Girder Bridge Closure

Abstract:

Closure sequences of rigid frame-continuous girder bridge are analyzed by calculation to compare girder deflection change, pier horizontal displacement maximum, girder and pier stress value. The results show that the first side span-second side span-mid span closure sequence causes the largest girder vertical displacement and others cause almost the same vertical displacement; side piers pier top horizontal displacement is larger than middle piers whatever the closure sequence is, closure sequences could not change the stress of the girder and pier. The first side span-mid span-second side span closure sequence should be preferred.
