BRIDGE ANCHORAGE (Contd)
BEARING PLATE DESIGN
The final step is to design a bearing plate for each deadman. Whenever a
deadman composed of wood is used, apply a bearing plate to prevent the cable from
cutting into the wood. The two types of bearing plates are flat and formed, each
with its particular advantages. The flat plate is easily fabricated. The formed
bearing plate can be made of a thin piece of steel. (Refer to figure 17.)
Flat. Given the size of the deadman face and the diameter of the overhead cable,
flat bearing plates can be designed using table 12.
Formed. Given the size of the deadman face and the diameter of the overhead
cable, the dimensions for a formed bearing plate can be determined using table 13.
