Beams and Girders with Corrugated Webs

梁和梁的经济设计通常要求薄腹板。随着焊接技术的进步，在欧洲和日本，装配式预制梁逐渐取代轧制型钢。该提案的目的是研究具有波纹腹板的梁和梁的行为和破坏。调查将包括确定最有效的波纹形状，以及相关的成形和焊接方法。该方法将包括对具有波纹腹板的梁和梁在面内剪切，面内弯曲及其组合下的行为的实验和分析研究。研究结果将包括半经验方法来预测波纹腹板梁和梁的极限承载力，并指导设计准则。

Economical design of beams and girders normally requires thin webs. With the advancement in welding technology, pre-manufactured beams with built-up sections are gradually replacing beams made of rolled shapes in Europe and Japan. The objective of the proposal is to study the behavior, to failure, of beams and girders with corrugated webs. The investigation will include identification of the most efficient shape of corrugation, and the associated methods of forming and welding. The approach will consist of experimental and analytical investigations of the behavior of beams and girders with corrugated webs under in-plane shear, in-plane bending, and combinations thereof. The results will include semi-empirical methods to predict the ultimate capacity of beams and girders with corrugated webs and a guide to design criteria.
