An engineered wood construction system for high performance structures using pre-stressed tendons and replaceable energy dissipaters

摘要

An energy absorbing system for a building is disclosed. The system includes at least one connection (T) between an engineered wood load bearing element (P) of the building and another load bearing element (P) or a foundation of the building (F). The connection (T) has at least one high tensile strength tendon tying the load bearing elements (P) or the load bearing element (P) and the foundation (F) together. The connection (T) is in tension to pre-stress the connection (T) while allowing controlled relative movement between the load bearing elements (P) or the load bearing element (P) and the foundation, during a loading event. One or more energy dissipaters (D, E) are replaceably connected between the load bearing elements (P) or load bearing element (P) and the foundation (F), which will absorb energy from a loading event (Z) causing relative movement of the connection (T).
