Load on quay deck

Load on a quay deck is the full set of design actions on the trafficked surface and the structure below it: the uniform live-load surcharge, point and wheel loads from handling equipment, crane-rail loads, mooring-bollard pull, and the dead load of the deck itself. Container yards are designed for uniform loads of about 30 to 60 kN/m2 with concentrated wheel loads from RTGs, straddle carriers, and reach-stackers, while crane rails carry the wheel loads of a ship-to-shore gantry. The deck is checked for bending, punching shear, and pavement fatigue under the governing load case, to BS 6349-1 and PIANC pavement guidance. The same surcharge feeds the earth-pressure calculation for the wall behind.
