| Summary: | The static analysis of the indeterminate three-bar structure is developed using
the Castigliano’s first theorem, taking the lengths and inclination angles as variables.
Some reductions are applied in the resulting set of equations to approximate them to
the references models. From now on, the minimum mass optimization model with
restrictions is established. Then, the Optimality Criterion linear resizing optimization
rule algorithm for the unbounded and bounded design variables is applied in two
numerical cases. The analytical and Matlab Optimization Toolbox results are also
obtained and they demonstrate the Optimality Criterion linear resizing rule effectiveness
in structural optimization with a minimum mass objective and size restrictions. |
