Estudo da otimização de estruturas de cobertura em madeira levando-se em conta as características necessárias ao conforto térmico.

Abstract

This work presents structural calculus for wood truss frame shelter. Three wood species were used (two from cultivated forest and a native one). Three span values (5m, 10m and 15m) were used to obtain curves to make possible rational wood use. The architectonic project was chosen in accordance to thermal comfort parameters. It was verified that wood consumption per shelter area decreases from denser species to lighter ones for all spans when the curves obtained were used. The highest difference was found between the higher and smaller density for the larger span (15m). When one uses the plot of the costs per area, the curve is inverse. This plot shows that woods from cultivated forests are more interesting from the economical point of view.
