| (1)确定桥架宽度、层数、支撑点的型式和间距、以及电缆在各层桥架上的分布。 (1) Determine the width of the bridge, the number of layers, the type and spacing of the supporting points, and the distribution of the cable in the various layers of the bridge. (2)计算每层电缆的均布荷载(kN/ m2),初步确定桥架的型号、规格。 (2) calculate the uniform load of each cable (kN/ m2), initially determine the type and specification of the bridge. (3)按最大的电缆总均布荷载值来验算桥架强度。 (3) check the strength of the bridge according to the maximum total load of the cable. |
