Abstract

There is currently no accurate calculation procedure for determining the lateral-torsional buckling resistance of trapezoidally corrugated web girders. Therefore, a detailed investigation is performed in the frame of an experimental and numerical research program at the Department of Structural Engineering of the Budapest University of Technology and Economics. Based on the previous experimental results, a numerical model is developed to be used to determine the lateral-torsional buckling resistance by using deterministic method. The effect of flange size, corrugation geometry and boundary conditions are investigated. An improved design method is developed for the determination of the lateral-torsional buckling resistance of trapezoidally corrugated web girders.

波形腹板梁的侧向扭转屈曲阻力

目前还没有准确的计算程序来确定梯形波纹腹板梁的横向扭转屈曲阻力。因此，在布达佩斯科技经济大学结构工程系的实验和数值研究项目框架内进行了详细的研究。在前人实验结果的基础上，建立了一个数值模型，用确定性方法确定了侧向扭转屈曲阻力。研究了法兰尺寸、波纹几何形状和边界条件的影响。提出了一种确定梯形波纹腹板梁横向扭转屈曲阻力的改进设计方法。
