摘要：

Distortion of the cross-section, which commonly occurs in thin-walled box girder bridges that contain few intermediate diaphragms, may modify the distribution of stress throughout the structure to a significant degree. A method of analysis is presented which allows for the effects of cross-sectional distortion in addition to those of torsional warping. The approach is a rational extension of thin-walled beam theory and may be applied to continuous or simply-supported box girders of either straight or curved configuration in plan. As few test data of continuous girders were available against which the accuracy of the method could be verified, two scaled models-one straight, the other curved in plan-were fabricated for this purpose. The construction and testing of these models under a variety of concentrated and distributed torsional loads are briefly described. Results from these tests show excellent general agreement with those from the proposed analytical method.
