斜支臂弧形闸门的经济梁高

Economic beam height fo the inclined arm radial gate

针对斜支臂弧形闸门结构特点，并充分考虑面板和隔板对主梁高度的影响，以设计规范为依据，以抗弯和抗剪为控制性约束，并适当计入轴力，以主梁和隔板总重最轻为优化目标，经严格理论推导，作者提出了简便实用的经济梁高理论公式并给出算例。

Based on the structural features of the inclined arm radial gate and considering the influence of the face slab and the separators of the gate on the beam height, in design the bending and shearing resistance are taken as controlling papameters, and the axial force is also taken into account. The writer proposes his theoretical formula for economic beam heihgt, from which the primaty beam and the separators have the least weight.
