Design of the moisture monitoring system of the wooden structures of a five-storey timber building (CLT). The system consists of more than 60 measuring points with wireless sensors with data transmission to a computer. Together with the automatic monitoring system there is an extensive network of manual measurement points.
TimberTech has designed the network distribution of wireless sensors and receivers, manual measurement points and the most suitable way to install the system components within the existing building.
The possibility of cambering a timber beam by simply putting another beam on the top of it and inserting screws inclined at 45° relative to the elements axis is very useful in order to reduce deformation under load.
When rehabilitating historical masonry buildings it is certainly not rare to come to deal with sagged timber floors which cannot be buttressed due to heritage issues. A similar problem occurs when historical buildings are re-adapted to a new building usage which provides for an increase in floor loads. Therefore the development of a procedure which enables to “lift” a beam by just superposing a “dry reinforcement element”, could prove of some interest.
An analytical formulation has been proposed and experimental tests have been performed to validate the theoretical formulation. The resulting formula for determining the upward camber (given the mechanical properties of the beams
and of the fasteners) has shown the capability of reproducing the experimental behaviour with promising accuracy. The work led to the patent “METODO DI TRATTAMENTO DI TRAVI NONCHE’ STRUTTURA COMPOSITA PRECOMPRESSA” ITVR20120195.
Experimental investigation commissioned by the American Hardwood Export Council (AHEC), aimed at the mechanical characterization of the CLT panels
made of tulipwood (Liriodendron tulipifera) to be used for the realization of the Endless Stair (http://www.londondesignfestival.com/endless-stair) installed outside Tate Modern on the occasion of London Design Festival 2013.
Timbertech supervised the preparation of test specimens, the delamination tests, the design and interpretation of tests to determine the resistance to shear rolling of the panels.
