Analysis of Extended Hollo-Bolt connections: Combined failure in tension

Abstract: This paper investigates the combined failure mode of the Extended Hollo-Bolt (EHB) and the effect of the column thickness on the tensile behaviour of the blind fastener. A three-dimensional Finite Element (FE) model was developed, validated against experimental data and used in a parametric study. The non-linear numerical model, which simulates a single row of two EHB in tension, presents reliable results of the column and bolt failure modes in agreement with experimental data. It is concluded that the failure… Show more

“…Real size experiments are time-consuming and expensive, limiting the range of parameters that can be studied and the development of reliable analytical models. Alternatively, validated finite element (FE) models are used to capture the behaviour of complex systems, partially replacing more costly experiments, and giving access to inspect aspects that are not attainable during experiments [1]. Nevertheless, such models come with their own challenges, such as the associated large computational time and cost, convergence issues, uncertainties over replicating the correct phenomena outside of the fitted/validated ranges, etc., which prevent a systematic exploration of all the possible design parameters of the investigated problem.…”

“…Another example is the Thread-Fixed One-side Bolt (TFOB), which uses a similar concept to the Flowdrill system [16] that has been shown to be a good alternative to the traditional bolt and nut in engineering applications [17]. Finally, the blind fastener of interest in this article is the Extended Hollo-Bolt (EHB), modified from the HB by Tizani and Ridley-Ellis [18], which shows promising potential for use in moment-resisting connections [19][20][21][22].…”
