Failure mechanism of slender girder webs with a longitudinal stiffener under patch loading

The failure mechanism of slender girder webs stiffened by a single longitudinal stiffener under patch loading is addressed. Experimental results have shown that failure is due to crippling in the web panel formed between the loaded flange and the stiffener. This mechanism is similar to the one for u...

Zusammenfassung:The failure mechanism of slender girder webs stiffened by a single longitudinal stiffener under patch loading is addressed. Experimental results have shown that failure is due to crippling in the web panel formed between the loaded flange and the stiffener. This mechanism is similar to the one for unstiffened webs, which is characterized by the presence of elastoplastic deformations in the compression flange (plastic hinges) and in the web (yield lines). A longitudinal stiffener with normal position, b 1
