Finite analysis of glued-laminated timber girder bridges by Hanil Cha( )

1 edition published in 2004 in English and held by 1 WorldCat member library worldwide

A user friendly preprocessor to the ANSYS software was developed and used to model glulam girder bridges for finite element analysis. The program requires input data such as bridge dimensions, material properties, load, and load positions for analyzing the bridge. Five modeling options to idealize the connection between the bridge deck and the bridge girder are available in the developed program. The program also allows the user to model the bridge support conditions to account for end restraints. Shell elements were used to model the bridge deck while beam or shell elements can be utilized to model the bridge girders. Several output files that contain deflection, stress, and strain contours in the deck or girders are also generated during the analysis process. The file containing the deflection results can also be imported into the Excel software and be used to represent the results in a graphical format. Eight bridges with available experimental data were analyzed to calibrate finite elements results. A study was first conducted to investigate the sensitivity of the finite element results to the modeling technique, a slight change in the material properties, and the end conditions. The analytical results were generally in agreement with the experimental results. In addition, the analysis showed that the idealization of the support condition has a significant effect on the results
