The price of construction industry supplies in Brazil have experienced a historic raise, especially taking into account the great economic impact generated by the COVID-19 pandemic, in which steel prices increased by more than 92% and cement prices increased by more than 50%. Considering that in Brazil, in contrast to other countries, 80% of the construction work is executed using the reinforced concrete structural system, the cost associated to reinforced concrete constructions has risen substantially. In this scenario, there is an urgent need for rationalizing materials and optimizing structural designs that enable the construction of more economical buildings. Therefore, this research aims to present to engineering students, designers, builders, architects and engineers the financial impact of structural designs in reinforced concrete through a case study and comparative technical analysis between three structural designs for a 4-story residential building, 15m long, 9m wide, 12m high and with a total structured area of 526m², located on a 12m x 30m plot. Among these structural designs, the first two contemplate columns oriented in a single direction and the third contemplates mixed columns in both directions. The three structural designs in reinforced concrete refer to the 4-story residential building presented in the Building Manual published by the Brazilian Center for Steel Construction (CBCA) and comply with the recommendations established by the Brazilian Standard for the Design of Concrete Structures - NBR 6118. |
