The I-40 Mississippi River bridge has two arches made from a lattice of steel trusses.

I-40 密西西比河大桥有两个由钢桁架制成的拱门。

To accommodate this, a system of primary  bridges with steel trusses were designed for the parts between the towers.

为了适应这一点，为塔之间的部分设计了一个带有钢桁架的主桥系统。

A trench is dug for the foundations and then the whole station is  laid out on prefabricated steel trusses.

为地基挖了一条沟槽，然后将整个车站布置在预制钢桁架上。

Thirty-three inch deep floors made of prefabricated steel trusses would act as supports to stiffen the outside walls against the buckling forces of the wind-load pressures.

由预制钢桁架制成的 33 英寸深的地板将用作支撑，以加固外墙以抵抗风荷载压力的屈曲力。
