|
Two spans are attached together to make a continuous girder, with an expansion joint between each pair of spans. |
|
This would result in lower stresses in the girder or truss and meant that longer spans could be built. |
|
I would also like to show you a damaged and charred metal girder, which I found at the factory site, over a kilometre from where the explosion occurred. |
