THE SIX-STOREY timber-frame test building, TF2000, inside BRE's Cardington facility, has survived a collapse test where two load bearing wall panels on the ground floor were removed.
The disproportionate collapse test is part of the building regulations and requires that people have an hour to escape the building after the wall removal.
Researchers also proved that safe access for temporary propping was possible for eight hours and the test ran for 20 hours without distress to the building.
Martin Milner, timber engineering manager at TRADA Technology, said the next challenge was to apply the results to all timber frame layouts.
TRADA, BRE, DETR and industry are sponsoring TF2000, which aims to promote the benefits of timber frame construction and increase market confidence in the method.
Disproportionate collapse and fire are widely seen as particular problems for timber frame buildings which undermine such confidence.
