FUROS EM BLOCOS CERÂMICOS PARA FINS ESTRUTURAIS: UMA ABORDAGEM EXPERIMENTAL ESTÁTICA E DINÂMICA

Abstract

Structural masonry in the construction market is highly relevant given its high employment due to the competitiveness of the system in small and medium constructions. The ceramic block for structural masonry has a fundamental role in the system, being directly responsible for structural safety, and, therefore, must have its integrity preserved. However, it is usual to drill holes in structural walls for various purposes, and in extreme cases may compromise structural safety. This work, then, analyzes the effects of perforations on the static and dynamic properties of ceramic blocks for structural masonry, through the axial compression tests as well as the impulse excitation technique (IET). The changes in the compressive strength and the natural frequencies of the ceramic blocks were evaluated, observing the modifications that actually occurred and the level of their influence on the characteristics of the block.
