This topic is inspired by a suggestion from kbd512.
In discussion of domes that might be built on Mars, kbd512 suggested building a half-torus shaped structure.
Calliban had suggested a dome the size of the famous Superbowl at New Orleans.
Calliban's design would employ all native materials for the structure, and it would employ no imported materials at all for the primary structure.
kbd512's concept would employ a blend of local and imported materials.
This topic is offered for NewMars members who might wish to help kbd512 develop his idea.
It would be helpful to know the dimensions of the structure kbd512 has in mind.
The torus will have a diameter, and the ring of the torus will have a diameter.
In this early stage of definition of the concept, we do not know if kbd512 has a shape in mind for the cross section of the half ring.
Calliban has suggested a catenary shape so that forces are distributed evenly throughout the material of the wall of the ring.
This topic has significant growth potential.
The Stanford Torus is a model to study, since it dealt with many of the issues that will confront the designer of a half ring set on Mars.
I asked Google for help with the terminology:
AI Overview
Torus Shape – Definition, Examples, and Diagrams
A torus has two main diameters: the Major Diameter, which defines the overall size (center-to-center of the tube), and the Minor Diameter, which determines the thickness of the tube itself, often called the tube diameter or core diameter. These correspond to the Major Radius (distance from center of hole to center of tube) and Minor Radius (radius of the tube's cross-section) respectively.
Key Terms:
In the context of Calliban's dome, diameter is 200 meters at the ground, and the height is 120 meters.
The major and minor diameters remain to be defined for kbd512's ring habitat.
