Understanding the mechanism of progressive debonding bolts is great significance for underground safety. In this paper, both laboratory experiment and numerical simulation pull-out tests were performed. The experimental test specimens prepared using cement mortar material, a relationship between strength bolt uniaxial compressive (UCS) material specimen was established. locations crack develope...

Expansion of the offshore wind industry in seismically active areas has raised concerns regarding structural integrity turbines under earthquake loading. This paper details a 3D finite element study to investigate behaviour structure, and particular transition piece (TP), seismic loads. The work focuses on equivalent grouted connection TP-less designs, selected as promising design solutions for...

Abstract With the increased use of cable bolts in mining and civil projects worldwide, it is important to understanding performance these support structures different scenarios. The axial load transfer mechanisms six were investigated experimentally this research study. A large-scale pull-out testing apparatus with a capacity 1000 kN was designed manufactured as part investigation. common comme...

Fully grouted bolts are widely used in engineering. In order to deeply understand the load-transfer mechanism of a fully bolt, it is necessary analyze and study its mechanical behavior under axial cyclic load. First all, based on idea discretization force balance analysis each mass spring element, this proposes method for analyzing bolt—the element method. Second, model bolt established by usin...
