ABSTRACT: The use of non-renewable resources by the construction industry has
several environmental consequences, contributing to excessive energy
consumption and loss of materials. So, the construction sector is always in
search of improvement and methods that innovate the existing techniques, aiming
at the use of alternative and sustainable materials. Bamboo is a perennial
plant with fast growth rate and low cost that has great physical and mechanical
characteristics that assure its performance in the building environment. The
use of beams with total or partial replacement of steel by bamboo has been well
studied, due to the possibility of using the same design methods used in
reinforced concrete beams, since the bamboo-reinforced beams meet the
Bernoulli-Kirchoff bending theory. The objective of the work was to adapt a
design procedure into an electronic spreadsheet for bamboo reinforced concrete
beams subjected to four-point bending, with rectangular section, according to
Brazilian Standard NBR 6118 (2014). The spreadsheet was tested based on other
authors taking into consideration a steel double reinforcement. The resulting
values were equivalents to those obtained by the authors, validating the
efficiency of the worksheet. This methodology aims to optimize the design
process of beams and enable the substitution of steel by bamboo, highlighting
the validation, from the structural point of view, obtained by the authors.
