Análise dinâmica da interação de painéis de concreto pré-moldados com a estrutura principal, em diferentes zonas sísmicas

Abstract

The growth of large urban centers has created the need to build larger buildings to meet the population demand concentrated in small areas and there is a great tendency to use precast concrete elements in the construction of buildings. This work proposes a dynamic analysis in closure systems made by precast concrete panels, used as sealing elements of buildings in skeleton structures, for different seismic zones. For this, a simulation of a two-storey structure with closure was performed by horizontal pre-molded panels with openings and modal analysis and response spectrum analysis. Among other conclusions, it was possible to observe that the structure without the precast closing panels presents lower frequency because it presents lower rigidity compared to the closing structure and also verified that the closing panels contribute to the stiffening of the main structure for seismic actions.
