Buckling strength of deformable monosymmetric I-beams
Abstract An energy method of analysis is developed for studying the inelastic distortional buckling of welded monosymmetric I-beams with slender webs. The method uses the Cambridge model of residual stresses. An eigenproblem of order four is developed, and the microcomputer solution of the problem is very rapid. Following studies of the accuracy of the buckling solutions, the method is used to demonstrate the interaction between distortion and yielding of a monosymmetric I-beam with a slender web.
The article discusses the question of development of software for automated design of road wooden bridge spans. The adaptive pattern of elastic load distribution calculation based on obtained loading theorem providing optimal geometry elements choice is developed. It is given a comparison of the measured real spans deflection with the results of calculating using two methods.
