Análise comparativa do consumo de concreto e aço em fundações de sistemas construtivos – convencional x alvenaria estrutural – a partir de revisão bibliográfica

Abstract

Civil Engineering is grounded in efficiency, seeking to design, execute, and manage structures in a way that aligns safety, functionality, and aesthetics with economic feasibility. In this context, evaluating the cost of construction and its distribution across stages becomes essential, as the choice of construction system directly affects foundation design by generating different quantities of concrete and steel. This study analyzes the Constructed Frame System in Reinforced Concrete (Conventional System) and the Structural Masonry System from the perspective of material consumption in foundations. The methodology was based on a literature review and a comparative analysis of case studies available in the technical literature, assessing direct costs, quantities of concrete and steel, and the constructive differences between isolated footings and raft foundations used in each system. The results indicate that structural masonry tends to significantly reduce the consumption of concrete and steel in foundations when compared to the conventional system, mainly due to its simplified geometry and lower constructive complexity.
