Identificação de padrões de indicadores de consumo de sistemas estruturais

Abstract

This work consists in identifying the differences presented between buildings in relation to the adopted structural system, which focus is on the consumption differences between three determined systems: prestressed flat slab, ribbed slab with prestressed slab beams and Pavplus. The method adopted is the measurement of indicators in a given set of building projects for residential or commercial use that have adopted the chosen systems. These indicators are based on consumption and cost data for the execution of the typical pavement of these buildings, such as: mass of reinforcement used, consumption of concrete and shapes, area and perimeter. Statistical standards are obtained from the calculations of the indicators developed to represent aspects relevant to the description of structural projects. After comparing the results obtained for the indicators of each system, the magnitude of the differences found in each aspect described is determined. It was found that the flat slab system had higher values for most indicators, as well as higher cost per average area (R$ 171.36). The ribbed slab system with prestressed beam beams presented lower values for the indicators and lower cost per average area (R$ 146.59). The Pavplus system presented intermediate values, with R$ 164.52 as the average cost per area.
