Strain- time curve induced in bridge girder by the passage of a truck.
As a truck crosses a bridge, it induces strain in the girders.
Even without compensation for injury caused by a rolling girder, the lowly laborer could thus be a proud member of the ' ' imperial ' ' corporate body.
Researchers in the field talk of constructions that involve making girders, wheels etc., which are just one millionth of a millimetre long.
The replacement of the floor with ingenious trussed girders has already been mentioned.
Overall breadth across the fringe is 7 mm (est.) and the girder is strongly developed, especially frontally.
This girder system was connected to the periphery foundation, which supports the rest of the building.
The frames were constructed out of lightweight steel girders bolted together to support two vertical sheets of steel mesh.
