Characterising the Mechanical Loads Acting on Nuclear Packages during Rail Transportation
… study. Firstly, the design of equipment used to tie down a package to its conveyance has become more challenging with the recent trend of increasing package mass; often exceeding 100 tonnes. This difficulty is due to the advisory acceleration factors recommended for design. Despite widespread …

Exploration of versatile clamping mechanism and brace system for table attachment to lamp posts and poles in urban settings
… clamping mechanisms. In choosing a ratchet tie down strap as the final clamping mechanism, further improvements and designs were explored. Ultimately, an all in one table and brace system, involving an unfolding table surface was settled on.

Performance and Evaluation of a Variable-Speed Darrieus Wind Turbine
… of supporting the Darrieus are the . cable tie-down system and cantilevered system. The cable tie-down support method uses several guy cables which are connected from the ground to the top of the turbine rotor. The cantilevered system, which supports the rotor only at the base, is simpler …

Effect of Overturning Restraint on the Performance of Fully Sheathed and Perforated Timber Framed Shear Walls
… Effects of overturning restraint in the form of tie-down anchors and corner segments on light-frame shear walls with and without door and window openings were quantified. While the results are useful to refine a design methodology for shear walls containing openings, they also provide important …

Monotonic and Cyclic Performance of Long Shear Walls With Openings
… walls were forty feet in length and contained tie-down anchorage at the extreme ends of the wall only. Two replications of the five wall configurations were built. Each of the five wall configurations was tested using a: 1) monotonic displacement pattern and 2) sequential phased displacement …

The Racking Performance of Light-Frame Shear Walls
… were attached to the base by means of tie-down anchors and shear bolts. As opposed to engineered construction, conventionally built walls were secured to the base by nails or shear bolts only. The specimens were tested in a horizontal position with oriented strandboard (OSB) sheathing …

Improving the extragalactic distance scale using Cepheids in M33
… we quantify this effect as Cepheids are used to tie down the base of the extragalactic distance scale. Without an accurate calibration for the nearest distances, the distances we measure for all other objects will be subject to systematic uncertainties. This thesis studies how the chemical …

Modelling the crashworthiness of specialist wheelchair devices
… Unit take on the manufactures responsibilities, one of which is to ensure that the wheelchair is safe for use in transport.<br/><br/>Standard crash tests for production wheelchairs are destructive so are impractical to use for bespoke wheelchair designs meaning that the Clinical Engineers …

Analysis of Anchors and Bracing Configurations for Personal Fall Arrest Systems in Residential Construction
… account for a large number of injuries and fatalities each year (US Department of Labor, 2012). The effects of a fall are catastrophic to the workers and their families as well as the construction company and surrounding community. Prevention of these incidents has been the primary focus of …
