Development of the Analytical Model for the Fixed End Stub-Girder System

This paper presents several modeling methods to analyze the stub-girder system, testifies those methods base on actual test results for the behavior of the simply supported stub-girder system, and finally, by changing the boundary conditions in those models, predicts the behavior of the fixed end stub-girder system. Two different methods are used for the structural modeling. In the first method, the stub-girder is modeled as a vierendeel truss girder, and in the second method, as a finite element model. Both methods use the finite element analysis software package LUSAS™ for linearly elastic analyses and nonlinear analyses.
