Abstract
The static and dynamic characteristics of thin-walled twin-cell box girders were studied. The free vibrational characteristics of cellular structures were analyzed to improve the flexural and torsional rigidity. Numerical analyses of shear lag phenomenon, its influence on stress distributions and effect of rigidity of cross-section diaphragms on modal characteristics were performed. The results indicated that there existed an optimum combination of cross-section geometry proportioning, arrangement of cross-section diaphragms and stiffners of plate elements to obtain favorable stress patterns and modal characteristics for a box structure.
