Title: Torsional Strength and Behavior
of Spandrel Beams
Author(s): James O. Jirsa, John L. Baumgartner, and Nathan C. Mogbo
Publication: Journal Proceedings
Appears on pages(s): 926-943
Keywords: beams (supports) ; concrete slabs; cracking (fracturing) ; edge beams; moments; reinforced concrete; research; shear stress; spandrel beams; strains; torsion; ultimate strength.
Abstract:A series of nine specimens simulating the edge of a floor slab structure adjacent to an exterior column were tested to determine the torsional strength and behavior of typical spandrel beam configurations. The influence of the slab on the torsional strength and on the mode of failure of the spandrel beam was examined. The effects of shear-torsion and moment-torsion interaction on the torsional strength of the spandrel beam were estimated. The applicability of equations developed previously by other investigators for the torsional strength of isolated beams was examined.
