SCIA Corbel Design

Concrete Corbel Design

Concrete Corbel Design is a Design Form based calculation ready to be linked into SCIA Engineer. It serves for design and check of directly supported concrete corbel according to Eurocode 2 and implemented national annexes. The strut-and-tie model concept prescribed in EC2 is used for the analysis.



The concrete corbel is checked according to the regulations given in: Eurocode 2 Design of concrete structures Part 1-1: General rules and rules for buildings EN 1992-1-1:2004 (E). The conceptual framework according to article 5.6.4 of the code is involved, where the stress distribution in the discontinuity region of a concrete corbel is covered as strut-and-tie model (STM). The model consists of struts representing compressive stress fields, of ties representing the reinforcement, and of the connecting nodes. The forces in the elements of a strut-and-tie model is determined by maintaining the equilibrium with the applied loads in the ultimate limit state. The elements of strut-and-tie models is dimensioned according to the rules given in article 6.5.



Installation of the Corbel Design form to SCIA Engineer is as follows:

  1. Download the attached zip file with the sources
