Abstract

This paper studies interaction response between the spandrel beam and floor beams with different floor beam properties using ANSYS14.0 nonlinear models. A threedimensional finite element models have been established to provide a numerical solution as an alternative theoretical approach with some acceptable accuracy. The calculated ultimate loads, torque and angel of twist are compared with the experimental observation of twenty two statically indeterminate spandrel-floor beams and very good agreement is observed. Parametric study are presented to clarify the effect of floor beam length to the spandrel beam length ratio, depth of the floor beam to spandrel beam ratio. Empirical expressions are presented.
