Title: Computing the Refined Compression Field Theory
Author(s): A. M. Hernández-Díaz, and M. D. García-Román
Appears on pages(s): 143–147
Keywords: reinforced concrete, compression field theories, steel constitutive model, tension stiffening area, solvability
Abstract:In recent years, some modifications were introduced in the stress–strain relationship of the steel in order to develop amore efficient shear model for reinforced concrete members. The last contribution in this sense corresponding to the RefinedCompression Field Theory (RCFT, 2009); this theory proposed a steel constitutive model that has account the tension stiffeningarea prescribed by technical codes, what simplifies all the design process. However, under certain design conditions supported bysuch codes, the RCFT model does not provide a real (non-complex) solution for the steel yield strain when the prescribed tensionstiffening area is considered; then the load-strain response cannot be computed. In this technical note, the tension stiffening area isfixed in order to guarantee the application of the embedded steel constitutive model for all the standard design range.
