Benefits of technology

[0004]The invention provides an improved or at least alternative construction system for a building which provides at least a degree of protection against seismic and / or wind loading events, with the objective of avoiding or minimising structural damage to the building following such a loading event.

Problems solved by technology

In some cases very strong winds including cyclones can also cause building movement and structural damage.

Embodiment Construction

[0029]FIG. 1 shows two load bearing wall panels P formed of engineered wood such as LVL. FIG. 2 shows four such wall panels. The wall panels P stand on a foundation F. The wall panels are tied to the foundation by tendons T. Typically a tendon T comprises a rod or bar or wire or group thereof, or a cable of steel or alloy or carbon fibre or other high tensile strength material. A tendon T passes through a longitudinally extending cavity through each wall panel P. The tendons T are fixed in or to the foundation F, and at the top of the wall panels P by being anchored to an anchoring device 5. For example a threaded end of each tendon may pass through a plate and be secured with a bolt on the other side. This also enables the prestress force applied by the tendon to be adjusted, and enables the prestress force in the tendon to be increased / adjusted at intervals during the life of the building. Anchoring devices in other forms may be utilised, which preferably also allow for adjustment...

Abstract

A building includes a connection between an engineered wood load bearing element of the building such as a column, beam, or load bearing panel, and another load bearing element or a foundation of the building. At least one tendon ties the load bearing elements or the load bearing element and the foundation together. One or more energy dissipaters, replacably connected between the load bearing element and / or the foundation, absorb energy when a loading event causes relative movement of the connection. The engineered wood element maybe a laminated veneer lumber element, a parallel strand lumber element, or a glue laminated timber element, for example. Typically all of the load bearing elements of the building will be engineered wood elements. The building may be single or multi-storey. The building system enables lightweight low cost buildings, with energy dissipaters which may be replaced after extreme loading. The building may be prefabricated

Description

FIELD OF THE INVENTION[0001]The invention relates to a prestressed engineered wood building construction system which provides protection against extreme loading events such as seismic events or high wind loading or exceptional gravity loading on the building.BACKGROUND[0002]Over approximately the last decade there has been increased work on the design and development of construction systems for multi-storey concrete and steel buildings for regions subject to seismic activity, which not only prevent catastrophic failure of the building and protect life, but which also enable buildings to withstand earthquakes without structural damage, so as to reduce the economic cost of building repair and / or reconstruction as well as minimising business interruption (downtime) after an earthquake.[0003]In some cases very strong winds including cyclones can also cause building movement and structural damage.SUMMARY OF INVENTION[0004]The invention provides an improved or at least alternative constr...
