Efficient softened truss model for prestressed steel fiber concrete membrane elements

摘要: Abstract In this article, a recent version of the rotating-angle softened truss model proposed by authors, to compute full behavior prestressed concrete membrane elements under in-plane stresses, is extended steel fiber elements. For this, smeared constitutive relationships for component materials are modified include influence reinforcement . particular, new relationship in tension incorporated model. The model, called efficient concrete, checked against some experimental results found literature and related with panels tested shear up failure. It shown that able predict well all loading ranges, including after cracking reinforcement.
