2018-4-12 · crushing of web (3) buckling of thin flanges. Shear yield can only occur in very short spans and suitable web stiffeners will have to be designed. Local crushing is possible when concentrated loads act on unstiffened thin webs. Suitable stiffeners can be designed. This is a problem only when very wide flanges are employed.
The data were analyzed using the breakage factor defined by Lee and Farhoomand (1967). They evaluated the amount of crushing by defining the ratio f i D D 15 15 / where i D 15 is the diameter corresponding to 15% finer before shearing and f D 15 is the diameter still corresponding to 15% finer but after shearing occurred.
