Abstract

"The web crippling strength of cold-formed steel beams was investigated experimentally. In this investigation, due consideration was given to the possible influence of bending moment and shear force on the web-crippling loads.

For the subject of web crippling strength, the study involved the testing of 140 built-up beams having single unreinforced webs and 152 I-beams having double webs. In addition, 66 beam tests were conducted for the case of combined bending moment, shear and web crippling.

The experimental results obtained from the beam tests conducted at the University of Missouri-Rolla and the early tests performed previously at Cornell University were carefully evaluated for various loading conditions. Consequently, design formulas were derived on the basis of the available test data by using a regression analysis. These equations can be used to predict the web crippling loads of cold-formed steel beams when they are subjected to concentrated loads and/or reactions. The interaction formulas derived from this study reflect the influence of bending moment on the web strength against crippling"--Abstract, page iii.
