| Abstract | This paper presented an optimal design and sensitivity analysis of roof truss structures. The objective function was the weight of the roof truss, expressed as the weight of cords, webs and diagonal members. The seven design variables were taken intothe formulation. The Timoshenko beam model was use d to determine stress and deflection of the roof truss in terms of a closed form solution. Sixteen non-linear constrain equations were formulated according to AISC-89 code requirements. The solution was carried out by the MATHCAD program. An illustrative problem wassolved, and its results were presented and discussed. Finally the sensitivity analysis was included for selection of the design parameters. |
