Pier blocks serve as a transition from the posts supporting the girder to the concrete foundation footings. |
That queer fish with the long whiskers, the old man who preaches on the sand, often climbs up on to the nearest girder. |
Do a similar layout on the girder, so that you know exactly where each joist crosses the girder. |
On approaching the road overbridge, they noticed that the girder had collapsed and immediately stopped the train. |
The girder is in a position parallel to the ledger and supports the opposite end of the joists. |
You can't possibly blow it up, the mesh is mutually supporting, every girder bears the weight of everything above it. |
