In order to compare the two models of shear pins established above, a numerical analysis is conducted based on a two-span
continuous girder bridge shown in Fig.
Up to now, more than 20 continuous rigid frame bridges with the span larger than 200 m and more than 100 prestressed concrete
continuous girder bridges with the span between 100 and 200 m have been built or are under construction.
Converting a simply supported girder--which is without end constraints and is free to deform--to a
continuous girder results in the introduction of restraints in the structural system.
[24] established a simplified numerical model of RC
continuous girder bridge with finite element method.
