Structural analysis may be performed at three levels: global analysis, member analysis and local analysis. This chapter concerns global analysis – the calculation of deformations and internal forces and moments in beams and framed structures. It corresponds to clause 7, which has the following sub-clauses.
This clause, and some others, is more complex than before, because of the new policy on division of material between Parts 1-1 and 2 of EN 1994. Previously, provisions needed for bridges but rarely, if ever, used for buildings were in Part 2. Those that could be used for buildings as well as bridges have now been moved to Part 1-1 because they are ‘general’ (in theory). This gives greater prominence to elastic and inelastic methods of analysis. The new presentation of partial shear connection for beams is explained in the comment on clause 8.1.1.
