In order to protect plasterboard-lined partitions from damage, connections must be minimised and separation from the main structure must be provided, so that seismic movements can be accommodated.

Further information is available on the GIB website showing the principle of constructing partition framing with metal top and bottom tracks and friction-fitted metal or timber studs. Plasterboard linings are fixed to studs but not to the top and bottom tracks. These methods significantly reduce the risk of earthquake damage to gypsum plasterboard lined partitions in commercial construction. All details involve disconnection from main structural elements and a regular pattern of intermediate control joints.

Gypsum plasterboard packing strips behind joints ensure ongoing integrity of fire or noise control separations. Proprietary trims and finishes (such as the GIB Metal Trim Control Joint (P35)) can be employed to create clean shadow lines or other options chosen depending on architectural preference.

For more information on low damage solutions and repair strategies, please refer to the 'Earthquake Information' section under the 'Downloads and Resources' of the GIB Website.

Current wider industry initiatives seek to further develop suitable details for low-damage design of nonstructural elements. Information on the GIB Website will be updated as information becomes available.
