Strength and Serviceability of Inverted T-Beam Bent Caps Subject to Combined Flexure,Shear,and Torsion.

摘要

Concrete inverted T-beams that support precast stringers on the flanges of the inverted T were studied in 27load tests on seven specimens. Loading included combinations of flexural shear and torsional shear on prestressed and on nonprestressed specimens. Results provide advice for reinforcement details and design procedures applicable to the flanges as well as the shear and flexural strength of such beams.
