چکیده
Abstract This paper focuses on the experimental study of shear testing 15.2 mm, 25 t capacity seven wire cables at zero, 30° and 45° angles using two different facilities University Wollongong (UOW) Southern Queensland (USQ) in Toowoomba. A circular double-shear rig MK-IV was used for cable perpendicular to sheared joint faces (zero angle orientation), while carried out a larger-size rectangular-shaped rig. Testing based methodology wherein bolts were fully encapsulated Stratabinder HS inside three concrete blocks representing host rocks. part tri-universities-funded ACARP project C27040 awarded jointly New South Wales, Queensland. The objective programme provide essential information development numerical models that included not only technical parameters, but also behavioural outcomes from various tests with respect their effect nature failure, be it pure shear, tensile or tensile, pretension credibility effectiveness Barrel Wedge (B&W) anchorage system evaluated.

Numerical Investigation of Effect of Rock Bolt Angle on Shear Behavior of Rock Bridges
In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...
متن کاملInnovative approach to strata reinforcement in coal mines with reference to evaluation cable bolts shear strength
There is an increasing need to determine accurately the strength properties of tendons for an effective ground control on mines and underground structures as well as on modelling simulations. The strength properties of cables, used as cable bolts, have been evaluated mainly by their ultimate tensile strength, as this kind of test can be carried out in the field as well as in the laboratory. Onl...
