F.E.M. Simulation of the Building Frame Node Behavior during Seism

Abstract:

This paper presents a simulation made with ANSYS program on the stress and strain state of the node region of a reinforced concrete building subjected to earthquakes and equipped with devices for seism energy dissipation. This simulation includes the forces developed by the damping devices which act on these important nodes regions. The main goal of this simulation is to determine if the presence of the damping device at the supra-structure of the building is increasing the stresses and strains in the concrete and reinforcement bars of the node during earthquakes. For this study were used damping devices with damping forces depending on displacements. The results are very useful in the process of designing the damping system for the superstructure of the building and in the process of designing the reinforcements of the building nodes regions.
