Locally Buckled Plastic Hinge Behavior Under Monotonic and Cyclic Loading Condition
In order to clarify the influences of local buckling under monotonic and cyclic loading conditions, experimental studies were carried out on W8x10 A-36 structural steel members subjected...

Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...

Design Concepts for a Lunar Concrete Production Facility
This paper discusses concrete production fundamentals on the earth and identifies applicable features required for lunar concrete production. Production principles unique to the lunar...

An Analysis of an Inflatable Module for Planetary Surfaces
Design and construction of a structure on planetary surfaces requires addressing a host of issues not encountered on Earth. A modular quilted inflatable structure consisting of thin membranes...

Conceptual Design of Modules for a Lunar Base
This paper describes the development of cubically shaped aluminum modules which could be variously arranged to form living and working quarters for a lunar base. The module components...

Prototype Lunar Base Construction Using Indigenous Materials
A lunar base must be designed to withstand harsh lunar conditions, which include severe internal pressure loads and a high radiation level. Yet to provide for economical and rapid future...

Hedratecture in Severe Climates
There are still vast areas of the world that are almost untouched by human activity. There is need to make access to these regions with special new structures and there is also a need...

Lunar Habitats?Places for People
As part of President George Bush's Space Exploration Initiative, lunar bases or habitats are envisioned for long-term habitation by humans. This paper presents factors that should be considered...

The Design of a Permanent Lunar Research Station
The advancement of the United States efforts in space exploration and research requires the establishment of a permanent manned lunar research station. This paper explores the possible...

Evaluating Lunar Base Conceptual Designs
A large number of competing lunar base conceptual designs have been proposed in recent years. The range of assumptions and technologies used in these designs makes comparison difficult....

Lunar Base Requirements for Human Habitability
This paper presents some of the requirements for lunar surface habitation. Emphasis is placed on human factor and environment-behavior requirements that impact on habitability for medium-duration...

Design and Technology Assessment of Three Lunar Habitat Concepts
Three manned lunar habitat concepts, designed to support a crew of four for 28-30 days, are presented. Two concepts are based on Space Station Freedom structural elements and the third...

Analysis of Space Crane Articulated-Truss Joints
Three articulated-truss joint concepts for the space crane are studied to evaluate their static structural performance over a range of geometric design parameters. Emphasis is placed on...

Structural Design of the GN&C Navigation Base for the Space Station Freedom
The Space Station Freedom (SSF) pointing accuracy budget requires that the Guidance, Navigation and Control hardware maintain alignment within ? 0.1 degrees of arc. The ring laser gyros...

A Novel Aerobrake Design for a Mars Lander
A flexible/inflatable aerobrake is proposed for delivering small payloads to Mars as an alternative to propulsion landing. Some results that demonstrate feasibility are presented....

Structural Considerations in the Design of a Mars Mission Aerobrake
A new area of civil engineering is emerging. This area will provide structures for outposts on the moon, resource development and exploration of Space. Spacecraft traveling at very high...

Modeling and Analysis of Doubly Curved Aerobrake Truss Structures
Recent studies have indicated that vehicles designed for a piloted mission to Mars may have their initial Earth Orbit mass reduced by nearly a factor of two if aerobraking is used rather...

Structural Design Methodology of Large Space Structures
This paper discusses considerations and outlines a methodology for structural design of large space structures (LSS) deployed in low earth orbit. It includes definition of mission requirements,...

A Methodology for Development of Spaced-Based Assembly Operations
Designing and constructing a large space-based science facility requires the integration of constraints and design variables with assembly operations. Development of such a facility requires...

Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...
