The experiment hardware provides two end supports; one for completely rigid end fixings, whilst the other giving horizontal travel. Both supports create simple supports (knife edges) and have clamp plates which created fixed ends by restricting the end rotation of the test beam.
The test beams have a single point load applied using the fine screw jack mechanism with integral load cell supplied. The displacement of the test beam within its elastic and plastic regions is measured using a dial gauge and this along with the load cell output connect into the interface.
The model three (3) span bridge has a flat deck and solid spandrels to the three spans. The bridge is supported on the two inner piers and is anchored to the two outer piers to provide a pair of cantilevers on which the suspended centre span is carried. The four piers and the centre span supports incorporate reaction measuring load cells that connect directly to the Interface to give readings in Newton’s.
