VII.4.6: Interior Structure: Besides the hull and bulkhead assembly, there are several other major structural areas: the interior buildings for living and storage, and the window which allows light to enter the colony. Each of these must be designed with a combination of individual requirements including the constraint that they must be compatible with the existing hull structure. The following description outlines the design of these compartments. VII.4.6.1: Buildings: As described in Chapter VI, the interior housing is designed to provide between 55-60 m 2 per person. These buildings are constructed prior to the spin-up and pressurization of the colony. Therefore, the footings must be designed to ac~.'.:>mmodate the hull expansion. This necessitates the use of pin and pin-roller joints. The floors of large buildings must be curved to match the hull radius and should not deflect more than 0.5 cm under their maximum design load. These last criteria are necessary for the comfort of the inhabitants; the curved floor allows the same
