Base Design

The construction of a lunar base has been thought about for almost five decades. The earliest concepts dealt with size and shape concepts rather than actual design of structures and equipment. As the exploration of space has received emphasis in more recent times, the need to consider the factors of design and design approaches have received more attention. It still is not possible to completely rationalize the design of a habitat, for example, but we are now very aware of the need to include the fracture and fatigue properties of the materials of which the hardware of a lunar infrastructure is constructed. It is reasonably certain that the same techniques used for terrestrial designs can be used for lunar bases provided the space environment is taken into account. The extensive amount of research on fracture and fatigue that has been and is being conducted, along with the ease and speed of computation of their effects on alternative design features will be invaluable in providing a highly reliable, safe lunar base.

The University

<p>Research on low-damage systems has been significant in the past decade. These systems combine post- tensioning, which provides self-centring; and typically use replaceable devices, which give energy dissipation. WSP has used recent research, carried out at the University of Canterbury, on low-damage bridge piers and applied this into a real structure – the Wigram-Magdala Link Bridge. This is believed to be the first bridge in New Zealand and possibly worldwide to adopt such a system. Given this was the first application of the system to a real structure, there were some valuable learnings during design and construction. Firstly, the application of axial dissipaters has some limitations due to available material sizes, construction difficulty and aesthetics. Secondly, there is still some additional cost and complexity associated with using the low-damage system. Given these difficulties, this paper presents an alternative design philosophy which better captures the benefits of the low-damage system, which include cost-effective repair method, controlled damage and additional robustness and resilience. The alternative design philosophy presented is expected to result in reduced construction costs by reducing pier and foundation demands. Peak displacements and forces will be compared to the results from non-linear time history analysis to verify the performance of the low-damage connection using scaled ground motions. Furthermore, the paper will present the possible application of an alternative dissipation device, the lead extrusion damper, which can further improve the performance of low-damage connections.</p>

Hull Design

The paper presents an alternative design for a submarine pressure hull, which has no ring-stiffeners, but where shell instability and general instability are resisted by making the pressure hull of a swedged-shaped form. Calculations on two different-sized pressure hulls appear to indicate that the swedged-shaped hulls are more structurally efficient than their ring-stiffened equivalents.
