摘要：

A theoretical investigation into the transverse stresses in the flanges of a simply supported box girder, under a symmetrical static concentrated load acting at the mid-span, is conducted using the finite element technique. Substantial membrane transverse stresses are detected. An explanation of this phenomenon is presented. The explanation is investigated by dividing the box girder into two identical channels. A torque is introduced by virtue of the central load being offset transversely with respect to the shear centre of each channel, and hence membrane transverse stresses are induced. In order to verify the above allocation of cause to consequence, certain lines of enquiry in connection with the behaviour of open and closed thin-walled girders are pursued. Correlation between the results revealed by the finite element analysis and those determined using simple structural mechanics principles is indicated. © 1990.
