Abstract Offshore wind turbines consist of the main components tower, nacelle and rotor blades. Additionally, numerous secondary are connected to primary structure. These include amongst others boat landings, platforms, cable protection tubes corrosion systems. Usually, these elements structure by welding or bolts. Both joining techniques reduce fatigue performance inducing geometric and/or met...

Fatigue behavior of glulam moment resisting joint subjected to repeated cyclic loading has not been well clarified. In addition, the accuracy conventional design formulae for rotational stiffness and yield/ultimate should be discussed especially related method obtain material properties. this research, tests were conducted drift pined joints with insert-steel gusset plate tensile-bolted joint. ...

This paper is concerned with modelling damage and fracture in woven fabric CFRP single-lap bolted joints that fail by net-tension. The approach is based on the assumption that damage (matrix cracking, delamination and fibre tow fracture) initiates and propagates from the hole in a self-similar fashion. A traction-separation law (based on physically meaningful material parameters) is implemented...

Bolted joints are generally used to connect two or more mechanical structures due their ease of assembly and disassembly for maintenance. However, the problem vibration is one main challenges when tightness bolted insufficient, causing failures such as looseness resulting in disconnection. Looseness most common cause dynamically loaded joint structure failure. This study tested a simple bolt ob...
