Title: BUILDING COMPONENTS FOR JOINING STRUCTURAL MEMBERS
Abstract:
A connector is provided for connecting between a first and second structural members. The connector includes a load applying member which bears in use in a first direction against a crushable portion of the first structural member. A retainer retains the load applying member at an initial distance from the second structural member. A non-return mechanism can act in successive cycles of forced movement of the first structural member. When the first structural member is forcibly moved in a direction opposite the first direction the load applying member progressively crushes the crushable portion of the first structural member. When the first structural member is then moved in the first direction the retained location of the load applying member is moved in the first direction relative to the second structural member. In this way some or all of the play formed in the connection by crushing of the first structural member due to forced displacement in one direction, is taken up by the retainer during forced displacement of in the other direction. This enhances the energy absorbency of the connection during a large cyclical loading event such as an earthquake.
