摘　　要：采用黄金分割法,建立了有柱式钢管骨架日光温室前屋面骨架的内力分析优化模型。通过对7类常用曲线的分析,提出抛物线型是日光温室最理想的受力曲面。Analysing stress and strain in the frame of solar plastic greenhouse is the necessary means to assure normal function. The distribution and the maxmum value of stress and strain is directly related to the shape of the frame. Optimizing the shape to minimizing the peak value of stress and strain is the high way to design the greenhouse economically. In this paper, a model to analyse the stress in frame was established. With the optimizing principle, a parabola frame was seen as the best in the 7 groups of curves. By the model, we can get optimized rest of any size of plastic greenhouses withh an inner post.
