Abstract: A connector for connecting two structural components. The connector has a casing engaged and to move with a first of said structural components. The casing is of an elongate constant cross section interior within which is operative in a frictional sliding engagement a spring and damper assembly. This comprising of at least one damper to move with a second of said structural components and contacting the interior of the casing and able to slide in frictional contact with the casing. A spring is able to be elastically deformed by and between the damper and the casing when the damper and casing are in relative motion to bias the two structural components towards their initial relative position.

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.

Abstract: A slip connector to connect first and second members of a structure to allow relative but resisted movement, and to at least in part return any movement. The connector includes a first component and second component, each with mutually slidable ramped surfaces contiguous. The first and second components are connectable to the respective first and second members of the structure, and there is at least one resilient fixer to hold the two components contiguous so that the line(s) of action of the fixer(s) is/are oblique to the slidable surfaces held contiguous.
