Structural optimization of plane frame and analyze of the static effect of the wind

Resumo

Structural optimization is used in engineering in order to find elements with optimal characteristics,
such as the size of the cross-sections. From this determination it is possible to obtain the weight of the structure,
and to find the optimal results it is necessary that some constraints are met, such maximum stresses and
displacements. The teaching-learning based optimization method (TLBO) can be used to solve structural problems,
making a correlation with a class of students. In this case, students' performance is measured through grades, where
in the structural system the grades correspond to weight. The consideration of wind forces in a structural design is
essential, as these loads can generate high efforts and require larger dimensions for the elements. The Brazilian
standard NBR 6123:1988 regulates the application of wind forces in buildings, both for static and dynamic
analysis. Thus, this work aims to analyze a building with application of forces due to static wind loads, as well as
the structural optimization of a plane frame. The teaching-learning based optimization method will be used in
order to determine the areas of the cross sections, being developed through the Matlab software based on the Finite
Element Method.
