Calculation of Continuous Beam Over Two Spans by Means of Plastic–Plastic Procedure
This chapter designs a two‐span composite beam according to the plastic–plastic procedure. In this case, action effects are calculated by rigid plastic global analysis, and the resistance to bending is based on a plastic model. For this procedure, all cross‐sections of the composite beam should be in class 1. The continuous beam has changed the static system from statically indeterminate to statically determinate. Rigid plastic global analysis can be used for ultimate limit state verifications other than fatigue. Also, this method is not applicable in cases where second‐order effects have to be considered. For calculation internal forces, bending moments and deformations at serviceability limit state, the elastic global analysis should be used. The restrictions on the application of rigid plastic global analysis given in clause 5.4.5, EN 1994‐1‐1, are such that linear ‐ elastic global analysis is often used for composite beams.
