The purpose of this paper is the development of simplified numerical tools dedicated to seismic analysis of reinforced concrete structures. Beam formulation and constitutive relationships are described to simulate the behavior of shear walls under complex loadings. The attention of this work focuses on the torsion effects and the way to account for cross section wraping for simplified analysis.
