Stiffness Modelling of Large Timber Connections in Stability Trusses

The demand for timber buildings is rising because of the need to make the construction industry more sustainable. Eurocode 5 provides guidance in the design process of timber structures. Numerical modelling is generally used for complex structures like multi-storey timber buildings. Currently, there is limited understanding of the serviceability...

Vibration Performance of a CLT floor system: Comparison of onsite measurements with and without architectural finishing to numerical and analytical calculations

Currently, the building industry contributes to up to 50% of climate change. A way to reduce the impact is by replacing current building materials with more environmentally friendly materials, such as timber. Engineered wood products, such as cross-laminated timber (CLT) panels, have increased strength, stiffness, and stability which enables...

Connection of timber foundation piles to concrete extension piles

In this work, the relationship for a socket-type connection in wooden foundation piles is investigated, and a trilinear moment-rotation diagram was determined by means of experiment.<br/>Numerical and analytical models confirmed that the material properties for compression perpendicular to the grain are governing for the connections’ strength...

Load carrying capacity of multiple fastener steel to bamboo joints loaded parallel to the fibre direction

Laminated bamboo could be a promising material when it comes to large span roofing structures where often truss structures are adopted. It is assumed that connection design used for timber trusses can also be applied in laminated bamboo trusses. For this research truss nodes with slotted-in steel plates are considered. This research will focus...

Dowel type connections in laminated bamboo with multiple slotted-in steel plates

The main focus of this research was testing of dowel-type connections using slotted-in steel plates in laminated bamboo loaded parallel-to-grain. Since laminated bamboo is a relatively new material, a proper design standard and design formulas have not yet been established. Strength testing of this material is currently being done by a number of...

Load carrying capacity of large mortise and tenon joints in wooden mitre gates

Wooden mitre gates are used for centuries in waterways and canals. For newly built as well as the renewal of such gates, a number of wood species is used, ranging from oak to dense tropical hardwoods. As mitre gates have high loads to withstand, their strength verification has become more and more important. As strength verification rules for...
