Dimensionamento estrutural e análise comparativa de custos de um edifício de alvenaria estrutural versus concreto armado.

Abstract

This study aims to conduct an assessment of the economic variability of the construction system that is more beneficial for a model building, comparing the conventional reinforced concrete system to structural masonry system, through structural design of the model building for the structural masonry system, already scaled in reinforced concrete. Due to the growth of civil construction and, especially, the rise of new technologies, it is required a preliminary study of each project, taking into account, among other aspects, the architectural design, loads acting on structure and height of the contruction, for adoption of the construction system that is technical and economically suitable for each case. Firstly, a brief literature review of the two construction systems is presented, describing its main characteristics as well as presenting the theoretical framework used for the structural design. Later, is discussed the structural design of the masonry building and elements in reinforced concrete that may be needed. Finally, the quantitative structure and materials used in sealing the two systems are surveyed and budgeted. Based on the budget results presented, a comparative cost analysis between the two systems is conducted, for the model building used in the study, in order to present the civil construction workers estimate costs that can be used as a reference when choosing the construction system to be adopted.
