Estudo e análise do impacto do efeito torsor em edifícios de pequeno porte concebidos em alvenaria estrutural

Abstract

Structural masonry is a growing construction technique widely used in small and medium sized buildings, known for its economic advantages and modernity. In the context of the structural system, walls play a central role, replacing traditional structural elements such as columns and beams to bear loads. However, the influence of torsional effects in structurally masonry buildings with asymmetrical layouts is an underexplored topic in the literature, despite the unanimous agreement within the scientific community regarding its importance. This study aims to analyze the effects of torsion in small-scale structurally masonry buildings, utilizing a practical example of a four-story building to assess its impact on structural design. The project's development follows a methodology that encompasses all stages of the process, from architectural design to structural dimensioning. The results indicate that in small-scale structurally masonry buildings with asymmetrical layouts, torsional effects do not significantly affect structural design. The material characteristics and the absence of reinforcements remain unchanged when compared to conventional design, demonstrating the dispensability of torsional effects. Therefore, under these conditions, it is reasonable to consider the influence of torsion as negligible in the design of small-scale structurally masonry buildings.
