Fatigue of Preloaded Bolted Connections with Injection Bolts

Steel-reinforced resin for bolted shear connectors: Confined behaviour under quasi-static cyclic loading

“…Injection bolts have also been studied for application in hybrid structures (steel-FRP) for innovative light-weight bridges [8][9][10], in crane girders [11], towers for wind turbines and stadium roofs [7]. Fatigue tests on preloaded injected bolted connections were conducted by several authors showing that there is a contribute to reduce the scatter on the results and to improve the fatigue life [12][13][14][15].…”

Probabilistic strain-fatigue life performance based on stochastic analysis of structural and WAAM-stainless steels

“…De Jesus [26] presented a study of fatigue strength modelling based on local approach and probabilistic CFC model for riveted connections. Other studies [27][28][29][30][31] on the fatigue strength modeling of materials and structural connections were made based on a linear regression analysis combined with the application of probabilistic distribution functions -Normal, Weibull, etc. Reliable Wöhler curves based on the Stüssi model and the Weibull distribution function were suggested by Caiza et al [32] to strengthen modelling of structural details.…”

Testing and design of stainless steel staggered bolted connections

“…However, given that the initial material cost of stainless steel is around 3-4 times that of carbon steel, it may not be economical or suitable for the construction of complete structures, even when whole-life costing is considered; it may though be desirable to adopt stainless steel for key components of structures in strategic locations, for example, in the connection regions. In these regions, the high ductility and energy absorption capacity of stainless steel can lead to enhanced robustness and resilience under extreme and fatigue loadings [6][7][8]. This has prompted experimental, numerical and analytical studies into different types of stainless steel connection.…”
