The use of timber in structures like guard-rail systems requires knowledge about the behaviour at high loading rates. The present study aims at presenting a state of art report with respect to the impact bending strength of timber and to some extent to the behaviour of timber joints at high loading rates. The literature review indicates a difference in the experimental results and the conclusio...

Integral Mechanical Attachment (IMA) uses features in the form of components for their connection. In addition to the transfer of forces, locator features are used as integral assembly guides. Prismatic, single-degree-offreedom (1DOF) joints only allow for a single assembly motion and therefore a simple, rapid and precise assembly. In modern timber construction, such CNC-fabricated 1DOF joints ...

Because of it’s economy, high strength-to-weight ratio and stiffness-to-weight ratio, wood can compete with steel and reinforced concrete as a construction material in a market with an increasing demand for large structures such as community buildings, gymnasiums, schools and bridges. However, continued acceptance or expansion in this market, particularly in high wind or seismic areas, depends ...

In European seismic areas timber structures are found as building frames, in combination with masonry infills, in bridges, but most frequently in roof structures and floor slabs of traditional buildings. Seismic strengthening of existing structures should provide a well-defined and simple path to seismic forces, maintain timber members elastic, and develop as much as possible the post-elastic b...

AMPTIAC Directory ... 15 The beginning In late 1993, the Mechanics and Surface Interactions Branch of the Air Force Research Laboratory’s Materials Directorate (AFRL/MLBM) was tasked to investigate the accuracy of the analysis methods used to predict the strength of bolted composite joints used on high-performance fighter aircraft such as the F-22 Raptor. The strength of bolted joints is essent...
