Análise da viabilidade econômica entre a viga baldrame e o sistema de pedra argamassada na alvenaria estrutural.

Abstract

The demand for efficient construction methods that integrate quality, cost, time, and sustainability has driven technological advancements. Structural masonry stands out in the market due to its relatively lower cost. In response to the need for cost reduction, comparative studies focus particularly on foundations to identify more effective solutions in terms of materials and economy. In this context, a comparative analysis was conducted between two types of foundations in structural masonry: mortar stone and strip footing with isolated footings, with the aim of determining the most economical model. To achieve this, a structural modulation of the building was developed to quantify the acting loads. The data were used to size both foundations, varying loads and soil pressures to analyze different scenarios. The comparison of quantities, based on SINAPI and SEINFRA/CE databases, revealed that the mortar stone system is more economically viable in all scenarios studied in this research. It is concluded that comparative studies are essential for decision-making, aiming at cost reduction in construction projects.
