tests; (7) Digital Image Correlation is a promising technique for bridge deflection measurements, also thanks to the increasing resolution of the last digital cameras [26–28]. The use of a laser beam for measuring deflections is by now a consolidated technique. read more
Beam bridges . A beam or "girder" bridge is the simplest kind of bridge. In the past they may have taken the form of a log across a stream but today they are more familiar to us large box steel girder bridges. A beam bridge needs to be stiff. It needs to resist twisting and bending under load. read more
Beam bridges, also known as stringer bridges, are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported. read more
Simple beam bridges may use wood beams, but modern beam bridges use light and strong materials. Construction of a multi-beam bridge involves the use of a bridge crane, beam clamp for holding, and other tools. Bridge load rating is done to determine the loads that can be safely carried. read more
