Spatial Prefabrication in Timber Structures

Numerical Modelling of Timber Braced Frame Masonry Structures (Dhajji Dewari)

This paper presents numerical modeling technique for Dhajji-Dewari structures (timber-braced rubble stone masonry), and its application for the evaluation of in-plane force-deformation capacity of Dhajji wall panels of different configuration of bracings. Dhajji structures are mainly composed of vertical and horizontal timber posts and braced using diagonal bracings and horizontal studs. Wall o...

Composite Repair of Timber Structures

Curved Folded Plate Timber Structures

Current research at the laboratory for timber construction IBOIS at EPFL focuses on shell structures. Two main families are investigated: shells made of linear elements, as timber rib shells, and shells made of surface elements, typically folded plate structures. With regard to timber rib shells, bent linear timber elements are used to create the shape of a shell. With folded plate structures, ...

Acquaintance of the ancient timber structures

Ancient timber load-bearing structures are the ancestors of the modern framed structures therefore deserve special attention and careful conservation. The peculiarity of the members to undergo, when loaded, consistent deformations before ruptures occur, allowed in the past architects to understand the behaviour of the structures, evaluate their dimensioning criteria, express reliability judgeme...

Cutting construction wastes by prefabrication

Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...
