高跨比
[建] depth-span ratio
- 随着高跨比的增加，梁体整体裂缝程度呈减小趋势。
The whole crack parameter of bridges decreases, going along with the increase of depth-span ratio. - 对于相对较小的荷载，可以找到立体钢桁架及立体预应力钢桁架的经济高跨比范围。
For the relatively smaller loads, the economical height-to-span ratio scopes of space steel trusses and space prestressed steel trusses can be found. - 结果表明，当高跨比大于1/5时，加载位置对FGM梁的位移和应力分布有显著影响，为校验FGM梁近似理论和数值方法的有效性提供了参考。
The results show that when the thickness to span ratio is approximately larger than 1/5, loading position will have marked influence on the axial displacement and stress distributions of FGM beams.
