Dynamic Load of airplanes on Bridge
Dynamic Load of airplanes on Bridge
(OP)
I am reviewing a design for a major airport. The airport is extending one of the runways. To do this a concrete frame bridge is beign proposed. The roof of the frame structure will be covered with reinforced concerete pavement where the airplanes will land. Has this been done before?

Planes weigh more when they take off than when they land since they're full of fuel.
The planes don't ususally touch down at the very beginning of the runway.
The pilots intentionally apply the load gradually to the runway to make a softer landing.
I know this doesn't answer your question, but maybe it will help.

Also braking forces and failure load of the landing gear shall be considered.
Try to find or buy ACI 343R-95 "Analysis and Design of Reinforced Concrete Bridge Structures". Project budget should be able to cover this expense.
Good luck.

Under wet conditions, a good pilot will intentionally impact the runway quite severely, so as to avoid potential aqua-planing. I learnt that years ago when my plane landed at Hong Kong in a severe rainstorm. We barely knew when our plane had landed at Darwin, and were very impressed by the landing skill of the Qantas pilot; at Hong Kong we were violently shaken by the touch-down impact (and wrongly blamed it on misjudgement by the co-pilot).
And of course, human error and incompetence is always a possibility.
