Isolated RC wall subjected to biaxial bending moment and axial force

摘要

A numerical study using nonlinear finite element analysis is performed to investigate the behavior of isolated reinforced concrete walls subjected to combined axial force and in-plane and out-of- plane bending moments. For a nonlinear finite element analysis, a computer program addressing material and geometric nonlinearities was developed. Through numerical studies, the internal force distribution in the cross-section is idealized, and then a new design method, different form the existing methods based the cross-section is idealized, and then a new design method, different form the eixsting methods based on the plane section hypothesis was developed.
