Evaluation of Dynamic Parameters of the Vierendeel System under Cyclic Loading

Vierendeel systems are widely used because of not using diagonal members, providing free space for passage of pipes and ducts, ability to cover the more height of the structure, creation a unique view for thestructure and, so on. In engineering design, due to lack of the theory on the vierendeel system’s stiffness,design depends on experience. In this paper, for evaluation of nonlinear behavior of the structure a numerical analysis on one-story, three-story and five-story vierendeel systems under cyclic loading is presented. OpenSees software is used in order to evaluate the behavior of the system considering both thematerial and geometric non-linearity. So, the seismic parameters of the system, such as yield load,deformation, ductility, energy dissipation, and strength and rigidity degradation are obtained. Then, the influences of the vierendeel system height and its height over width ratio are studied.
