Description of Shear Center
The Shear Center equipment is used for studying the plane of traverse loading without twisting for selected standard sections. Shear Center is to be used with Universal Base Frame or Universal Structural Frame. Interchangeable beam specimens are made from 1.2 mm steel sheet or approximate equal with welded-on end plates and a central loading plate which has a provision at the bottom for loading at different eccentricities from the beam axis. The end plates are attached to two flanged supports. A load is hung at the bottom of the central loading plate and two dial indicators are used to measure deflections of both ends of the plate. The plane of zero twist is the plane of shear center.
