Abstract: An energy dissipation device includes a primary core module, a housing module, first and second outer plates, an energy dissipation unit, first and second preload tension members and a resilient compression unit. When the primary core module and the housing module are subjected to an external force, the first and second preload tension members stretched by the external force, and the resilient compression unit is compressed, such that relative movement between the primary core module and the housing module is generated. The energy dissipation unit generates a retarding force during the relative movement between the primary core module and the housing module, so as to dissipate the kinetic energy generated as a result of the external force.
