It was really some advice on the general design approach that I was after.... but if it helps - the ledger needs to withstand an accidental load of 4.3kN, the position of the load along the ledger is not fixed [will depend on where fall occurs!]. The ledger is currently a 38x89mm C16 timber...
I have a horizontal timber ledger that is nailed at 200mm [8"] centres along its centre line to a supporting timber structure. The ledger will need to support a substantial point load.
Am I right in thinking that if the ledger is stiff enough I can assume that the shear load will be shared...
