| 摘 要： | 为了简化梁的截面形状及材料选择时的计算过程,基于圆截面的特殊截面性质,推导出2个截面形状参数,使得抗弯梁截面形状的选择有了更加直接的且易比较的算法;从强度和刚度最大化且所用材料最少出发,得出了另2个可同时选择材料和截面形状的计算公式.

| Abstract: | Based on cylindrical cross-section, two shape factors were deduced ,which made calculation for selection of beam cross-section easier and direct. Considering the combinations of section shape and material stiffness/strength for minimal weight, another two expressions were derived. |
