Distributed load

The kind of load which is spread along part, or the whole length, of a member. If it is spread evenly it is referred to as a uniformly distributed or u.d. load, and is the commonest load on a bridge, due to its own weight. Wind loading is usually treated as a u.d. load. This is in comparison with "point loads", where loads are concentrated at points on the bridge, e.g. at the nodes of framed structures.
