ESTUDO COMPARATIVO DE CUSTO COM MATERIAIS EM UM EDIFÍCIO RESIDENCIAL ANALISANDO SISTEMAS ESTRUTURAIS DISTINTOS: Concreto armado e Alvenaria estrutural

Abstract

The definition of the structural system for a project is of fundamental importance for the cost of the work, causing builders seek for alternatives that result in the implementation and rationalization of the system. These alternatives have the reinforced concrete structures, which are structures that have a joint connecting concrete with steel bars placed inside, this association provides elements with high resistance to compression and tensile stresses. The basic elements that make up this type of structure in buildings are pillars, beams and slabs with the use of sealing masonry. Another option is the use of masonry which is defined as a structural system where the walls are resilient elements capable of supporting other loads besides their own weight. The main components of the structure in masonry are: block, mortar, grout and steel. This work aims to develop a cost comparison with materials through structural designs for a residential building, designed with reinforced concrete structures arranged by columns, beams, solid slabs and concrete blocks for sealing and one in structural masonry blocks with concrete slab. Structural projects will be developed from the architectural design of a residential building that will be deployed in the city of Pouso Alegre - MG. The designs and details follow the recommendations prescribed by the regulatory norms of the bibliographic references. In carrying out the comparative spreadsheets were performed with the quantity and price of each existing composition, and thus can indicate the difference in cost of structural systems. Thus, it can be concluded that the system showed a masonry attractive alternative, obtaining a reduction in the costs related to the superstructure in relation to the structural system for reinforced concrete in the building in question.
