Stress Concentration Factors

The use of bolted joints to connect the transition piece and monopile is nowadays widely applied in the offshore wind industry. Traditionally, grouted connections were used in the early generation of offshore wind turbines, but the experienced failures in such connections led to an increased tendency towards bolted flange connections to join the transition piece and monopile in the new generation of offshore wind turbines. The bolts used for this purpose have high strength and huge sizes, and are subjected to a preload that is applied during the tightening process. The present study is focused on the analysis of preload effects on stress distribution in M72 bolted connections by considering different friction coefficients between the bolt and nut threads. The bolt is considered to be made of grade 10.9 steel, whereas the nut is assumed to be made of grade 8.8 steel, which is a softer material. Using the finite element commercial software package Abaqus, numerical models were developed and analysed to establish trends for stress distribution and plastic strains during the bolt tightening process, and to quantify stress concentration factors in individual engaged threads.

This article experimentally studies the behaviour of high-strength bolted connections with slot bolt holes under cyclic load to evaluate its seismic performance. A total of six specimens varying in the bolt diameters and pretension are designed and tested. The results show the connections with slot holes have good energy dissipation capacity. It is found that connections with M30 bolts, of which the hysteretic loops are fuller, have better energy dissipation capacity than that of M20 bolts connections. With the increase of number of loading cycles, the sliding force of the connections decreases. On the other hand, the ultimate bearing capacity of the connections does not decrease much both for M30 and M20 bolts. As the experiments proceed, the friction coefficients and the areas of the hysteresis curves decrease in a similar trend because of the smoothing of surfaces. The experimental results indicate the potential application of the connections with slot bolt holes as dual-function parts in structures to simultaneously provide stiffness and energy dissipation capacity.
