DEMONSTRATION MODEL INTER CONNECTED BRIDGE GIRDER APPARATUS
In case of bridges which have several longitudinal beams connected by cross-girders or continuous slab, a load any where on the bridge effects all the beams of the bridge even if a load is placed exactly on one of the beams, other beams also share the load and the loaded beams is not required to bear the full load. The problem of sharing of the load by all the beams is known as the load distribution problem in bridges.
Theoretically it is a highly complication problem whose exact solution has not been given so far. However experimentally the load shared by each beam can be found very easily. The load shared by each beam will be in the ratio of the maximum deflection suffered by each beam. Hence if vertical deflection of the entire beam is measured at the same transverse section passing through the load, the load supported by each beam can be easily estimated. Thus influence surface for each beam of the bridge can be experimentally traced.
