866 Bearings and joints
the structure.A particular example is a large expansion joint of the elastomeric type
in a bridge, where horizontal forces developed in moving the joint should be considered
in design or selection of the bearing which is to form the fixed point of the
deck.
28.4 Bearings and joints – other considerations
In design and detailing of bearings and joints, it should be remembered that the
positions where they exist may be positions of concentrated load application and/or
significant discontinuity in the structure. Care should be taken in design to establish
and preclude all likely means of deterioration and failure. This should extend
to adequate supervision to ensure correct installation, as many problems have been
attributed to substandard workmanship applied to an otherwise competent design.
The need for maintenance of all joints should be assessed, and adequate
allowance made where necessary for inspection, servicing, and facility of
replacement.
