ABSTRACT

Corrugated webs, in spite of their small thickness, are characterized by relatively high patch load carrying capacity. Some formulae for estimating patch load carrying capacity can be found in specialist literature. They were derived from different web failure mechanical models and values of patch load carrying capacity calculated from these formulae differ from one to another. Shaping of web folds in form of sinusoidal wave cause increase of web patch load carrying capacity in comparison with web with other shapes of folds. In experimental tests and numerical simulations it has been shown that, as well as in plate webs, in corrugated webs their patch load carrying capacity is dependent on the width of patch load application.
