The response of beams and plates under multiple loading is considered taking into account the inelastic interactions between moments and axial (in-plane) forces. The plastic analysis is based on distribution of stresses and strains in three dimensions so that yielding remains a function of the uniaxial state of stress in beams and of the biaxial state of stress in plates. The interaction effects between dynamic transverse loads and static in-plane loads is studied by using initial stress stiffness matrices that modify the original stiffness matrices. Detailed response behavior of beams and plates in combined loading is presented. The response characteristics are found to exhibit interaction instability properties.
