Abstract:
One of the most significant changes that have been introduced in the new Spanish standard EHE-08 is the re-definition of the ductility criteria for performing a linear structural analysis followed by limited moment redistribution, without an explicit check on the rotational capacity of the critical cross-sections. The present text contrasts these new criteria with the provisions given by internationally referenced codes of practice. The work focuses on rectangular reinforced concrete cross-sections, presenting recommendations on the minimum depth depending on the level of redistribution, closed form expressions for the design and an actualization of the non-dimensional diagram for bending moment versus reinforcement capacity. Finally, a practical example is solved, in which some recommendations on the design of slim floor beams are given, as well.
