Abstract

Presented in this paper are the results of a study where the web crippling capacity of multi-web deck sections subjected to End One-Flange loading (EOF) was investigated. A total of 148 tests were completed. New coefficients were established using the data from this study and any appropriate data from previous work. New resistance factors and factors of safety were also established. Also investigated in this study was the web crippling capacity of partially fastened deck sections and re-entrant deck type sections subjected to EOF loading. Seventy-seven (77) partially fastened multi-web decks and 36 re-entrant decks were tested in this study. It was found that partially fastened deck sections, unfastened re-entrant deck sections, and fastened re-entrant deck sections all behave in a similar manner to fully fastened multi-web deck sections and the same web crippling coefficients can be used with the same resistance factors and factors of safety.
