Development of a Rational Design Methodology for Precast Concrete Slender Spandrel Beams: Part 2, Analysis and Design Guidelines

In this paper, a rational method is developed for the design of normal-weight precast concrete slender spandrel beams with aspect ratios greater than or equal to 4.6. The design procedure was developed using data from a research program that included full-scale tests, finite element modeling and rational analysis. The overall research program validated the use of open web reinforcement in precast concrete slender spandrel beams and proposed a simplified procedure for design. It is recommended that the design for shear and torsion of slender precast concrete spandrel beams use the concept of resolving the applied torsion into two orthogonal vectors: a twisting component and a plate-bending component. The experimental and analytical results demonstrate that open web reinforcement designed according to the proposed procedure is safe and effective for reducing reinforcement congestion in the end regions of spandrel beams while allowing the beams to resist the combined effects of flexure, shear and torsion.
