Rotational force limiter and control structure having energy dissipator

摘要

It is a control structure that includes a pivot based rocker frame assembly integrated with a rotary yielding unit capable of generating a constant resistance yielding force through high elastic-plastic displacement and high ductility.The bending yielding plate is located within the rotation yielding unit, distributed around the rotational yielding unit, and has a particular boundary condition that allows for elastically plastic bending to high cycle elasto plastic displacement and high displacement and curvature ductility, while maintaining constant resistance yielding forces.A constant resistance yielding force generated by an interchangeable rotation unit allows the control structure to withstand an extreme earthquake (base input) with a constant resistance yielding force, and the plastic curvature within the yielding zone of the flexure plate of the rotating unit is maintained within their capacity. Within the control structure, the force within the support base and its mass or other structure that it can be shocked may be controlled and restricted.
