How to analyse a reinforced concrete beam (doubly reinforced) according to Eurocode 2 (EN1992). In order to get a reasonable design of doubly reinforced concrete beam, the design variables of the beam (b, d, A s, A s') must satisfy the following constraints: 2) (to be doubly reinforced beam). A bearing plate takes the reaction of a steel beam and distributes that force over a larger area that is made of a material that is not as strong as steel. Beams : Limit state analysis and design of singly reinforced, doubly reinforced, T and L beam sections. The behavior of the reinforced concrete coupling beam may be dominated by shear or by flexure as per ATC 40 , FEMA 273 , and FEMA 356. 75 to 80 of pt, lim. It explains the back.
