Material efficiency in timber high-rise buildings: A parametric study of externally braced timber stability systems considering the connection design

Timber high-rise buildings have been gaining in popularity. However, due to the low material stiffness of timber the stability systems of these buildings are often made with steel or concrete. To avoid this the material efficiency of the timber stability systems must be improved. The most material efficient stability systems for timber high-rise...

Probabilistic fatigue analysis on a central holed thick steel plate of C1 Wedge Connection for wind turbine tower assembling

Hole patterns are common in engineering design for connections and/or assembly purposes. Geometrical discontinuities can cause stress concentration in localized areas, making them more prone to fatigue crack initiation and influencing the fatigue life of the overall unit. In the past, much effort has been exerted on fatigue modelling of holed...

Timber and Steel Railway Bridge

Timber usage in construction works has increased over the past years due to its better environmental performance. Applying timber elements instead of steel or concrete decreases the emissions impact of the built environment. Architect firm ZJA and Iv-consult are interested in investigating a timber railway bridge as part of the Norwegian...

Flexural strength and rotation capacity of welded I-section steel beams with longitudinally profiled flanges

Application of longitudinally profiled (LP) steel plate in the flange of flexural members may provide a good solution to optimize their mechanical performance and to improve the efficiency of steel use, whilst existing design codes provide no design guidance or prediction methodology for such advanced beams in terms of flexural behaviour. To...

Delamination toughening in a low carbon microalloyed steel plate rolled in the dual-phase region

It is still a big challenge to obtain excellent low-temperature toughness for bulk steel materials. Delamination is an effective method to improve low-temperature toughness. In the present study, delamination toughening in a low carbon microalloyed steel plate with elongated and ultrafine-grained microstructure rolled in the dual-phase region...

Optimization of steel plate girders in bending: Using FEM-analyses on S690 and S890 steel plate girders

A parametric study, using the FEM-software package ABAQUS, validated on experimental results found by Abspoel, was conducted on S690 steel plate girders to address if the results of the previous researches was valid. Using a slightly different analytical model the results show the maximum web slenderness of this steel grade in both 6000 mm2 and...

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...
