Development of Analysis Tools for RC Members Subjected to Three-Dimensional Combined Loads

This paper presents a new finite element-based model for analysis of reinforce concrete (RC) frames subjected to combined loading conditions. The proposed model is formulated to address the interaction between the axial force, biaxial shear, biaxial bending, and torsion. The shear mechanism along the beam is modeled by using the Timoshenko beam approach with curved three dimensional (3-D) frame elements with arbitrary cross-section geometry. The...
