Predicting the behavior of prestressed concrete membrane elements by refined rotating‐angle softened‐truss model with efficient solution procedure
This article presents a refined version of the rotating‐angle softened truss model (RA‐STM) with efficient solution procedure to predict the full behavior of prestressed concrete (PC) membrane elements under in‐plane stresses. The refined model incorporates the concrete tensile strength in the perpendicular direction to the concrete struts and an additional smeared constitutive law for the tensile concrete. In order to avoid the classical trial and error solution procedure used in previous versions of the RA‐STM, a new algorithm is presented which lead to a more efficient solution procedure with higher numerical stability. The reliability of the proposed model is verified with experimental data related with PC plates under in‐plane stresses, where good agreement is observed.
