Strength of a riveted steel rigid frame having a curved inner flange

Abstract

The distribution of stress in the knee of a riveter! steel rigid-frame specimcn having a curved inner Bange was investigated both experimentally and the oretically. A theory was developed which gives the stresses in the knee to the sam e order of accuracy as the ordinary beam the ory gives the stresses in the st rai ght legs of the frame. Reinforcing the outer corner of the knee and stiffening the web were shown to have little effect on the stress distribution in the frame. The maximum load that could be sustained by the specimen was determined.

Strength of a welded steel rigid frame

“…The results on a riveted specimen having straight flanges have been reported in RP1l30 [1]/ and on a riveted specimen having a curved inner flange in RP1l61 [2]. The results on a welded specimen having straight flanges are reported here.…”

“…The load was not applied through pin-connected shoes as in previous tests [1,2]. The end flanges of the specimen were in direct contact with the platens of the testing machine.…”
