Review of Elastic Analysis of Box Girder Bridges

GC Ezeokpube

Abstract


The importance of thin-walled box girder bridges has attracted the attention of researchers since the last five decades. A lot of literature has dealt with the analytical formulations as well as experimental investigations. Field studies have increased tremendously in the last decade. So far the agreement between the analytical and experimental results has been excellent and, therefore, has made it possible to augment a limited number of experimental tests with hundreds of analytical studies. Highlights of research efforts in published literature regarding the analysis methods and experimental studies related to the elastic analysis of box girder bridges have been presented in this review. Subjects discussed include: (1) Thin –Walled Curved Beam Theory; (2) BEF/EBEF Method; (3) Finite Segment Method; (4) Folded Plate Method; (5) Finite Difference Method; (6) Energy Variational Principle; (7) Grillage Analogy and Space Frame Methods; (8) Finite Element Method; (9) Finite Strip Method; (10) Simplified/Miscellaneous Methods; (11) Experimental  Studies.
