Design of Beam Ledge According to ACI 318-99 Spreadsheet
2020年8月14日 · Design of Beam Ledge According to ACI 318-99 Spreadsheet A reinforced-concrete beam having projecting ledges for receiving the ends of joists or the like. A beam is a structural element that primarily resists loads applied laterally to the beam’s axis (an element designed to carry primarily axial load would be a strut or column).

Development of design guidelines for ledges of L-shaped beams
This paper presents the development of the design procedure for the eighth edition of the PCI Design Handbook to evaluate the punching shear strength of ledges of L-shaped beams. Based on the failure surfaces observed throughout a comprehensive experimental program, an idealized failure surface was determined.
Ledge behavior and strength of long-span L-shaped beams. W. Lucier, Sami Rizkalla, Paul Zia, and Gary J. Klein The ledge punching-shear capacities predicted by the seventh edition of the PCI Design Handbook: Precast and Prestressed Concrete overestimate the …
In this paper, two promising tools are considered for the design of very important structural element, ledge in inverted-T beams. The tools are the strut-and-tie method, STM, for safe design and the nonlinear finite element analysis, NFEA, for optimization of structure efficiency.

Development of Design Guidelines for Ledges of L-Shaped Beams
L-shaped ledge beams are frequently used by the precast concrete industry to support floor systems such as double-tee beams. The ledges are typically subjected to heavy concentrated loads with eccentricity and must be carefully designed to effectively transfer these loads to the web of the beam.
