Modelling the damping effect for structures in reinforced concrete frames

[摘要] In this paper we study the influence of the damping on the stress and displacements response for a reinforced concrete structure P + 4. In this sense, it was used a mesh consisting of two overlapping layers with common junctions. A concrete layer and a reinforcement layer Therefore, a numerical study was carried out by the help of an especially made program (a rewriting of the NONSAP PC program where a graphic postprocessing software was created). Finally, we obtained the structural response from the effect of the concrete degradation in the areas of the plastic joints. The paper presents our recommendations regarding the use of damping for reinforced concrete structures.
