Publication: Journal Proceedings
Appears on pages(s): 459-479
Abstract:The tests reported are a part of an investigationof rigid frame bridges made at the University of Illinois. The knee-frames were designed to represent a portion of the rigid frame bridges at the junction of the vertical and horizontal members. Various types of fillets were used at the inside corner of the frame. and the effect of compression reinfor-ment was studied. Part of the frames were held under sustained load for I5 months. To supplement the tests, photoelastic studies bakelite were also made and scale models of resuIts compared with those from the structural members.
