Validação dos parâmetros alfa e gamaZ para edifícios em alvenaria estrutural

Abstract

The construction industry seeks more economical and efficient construction methods, a context in which structural masonry stands out. This study evaluates the representativeness and convergence of the normative parameters α and γz in the stability analysis of structural masonry buildings. For that, 12 structural models of three distinct buildings with 2, 4, 8, and 16 stories were analyzed. The results demonstrated a correlation between the parameters, expressed through a third-degree polynomial equation. It was concluded that the α and γz parameters converged toward the same indication on the importance of second-order effects, thereby validating the application of current normative criteria
