Interação entre paredes de alvenaria estrutural submetidas à ações verticais: análise da influência do uso de cinta de amarração

Abstract

The present work deals with a study on the behavior of structural masonry walls composed of concrete blocks and submitted to vertical actions. With the objective of analyzing numerically the efficiency of the intermediate mooring pole in the uniformization of loads in structural masonry walls submitted to vertical actions, interactions between groups of relatives were analyzed through the simulation of two buildings of the same height, architecture and cargo nature, differentiated only by presence or not of an intermediate tie. The modeling of the buildings was performed using the software SAP2000 V12, which simulates the elements based on the finite element method. The analyzes performed on the walls demonstrate the tendency of uniformity of loading when considering the interaction, while the presence of mooring strap does not produce a relevant effect in the uniformization o actions. Interaction rates between groups resulted in unrealistic values for the delimited group.
