| Abstract: | The full stress method is proposed for the optimal design of steel tube cross section of the double hyperbolic reticulated sheel used for a cooling tower,and a mathematics model of the reticulated shell is set up,according to the minimal weight of the structure The paper introduces implementation measures of the optimization in detail,and utilizing Visual Basic 6.0,it works out an optimal procedure of cross section of steel tube of vertical reticulated shell at the same time. An optimization design of a specific project is done with this procedure,the analysis of internal force of optimal cross section is as carried out on the conditions of different loading and the authors compare the analysis results of all kinds of situations Some valuable conclusions have been gotten |
