A corbel is a short cantilever projecting out from a column a wall or the side of a beam. CORBEL is a spreadsheet program written in MS-Excel for the purpose of analysis of a concrete corbel or bracket supporting a loading plate per ACI 318-05.

There are several typical modes of failure in the corbel. Corbels are mostly utilized in precast concrete construction to provide support to main beams and girders. 10541541 Mechanics and Design of Concrete Structures Spring 2004 Prof.

Design examples are included for both normal weight and lightweight concrete corbels using both the ACI 318-71 shear-friction provisions and the modified shear-friction theory. Ah 05As An 1111 where. Do you foresee any problems with this design.

In this example a column with corbel is modelled. Under certain conditions Eurocode 2 permits the use of strut and tie method for the analysis and design of corbels. A corbel is designed to support another member usually a beam or girder but may also be used to support a slab.

ACI 318-95 offers good information to the engineers and designer. 11-28 and 11-29 which are valid for ad 10 or if ad is limited to 05 a simpler method of design based on the shear-friction provisions of Section 11. The most common of which are yielding of the tension tie failure of the end anchorages of the tension tie either under the load point or in the column failure of the compression strut by crushing or shearing and local failures under the bearing plate.

ACI 318 restricts the term corbel to a member having span-to-depth ratio which is less than or equal to 10. The design of corbels is governed by the provisions of Section 1114 of ACI 318-711 Under these provisions corbel design may either be based on the rather complicated empirical Eqs.
