Structural Design Methodology of Large Space Structuresby Ralph J. Dornsife, Construction Engineering Research, Lab, Champaign, United States,
Abstract: 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, structural modeling and analysis, passive damping and active control system design, analysis of partial deployment configurations, ground-based testing, payload integration, on-orbit system verification, and on-orbit assessment of structural damage. This methodology is intended to assist the structural engineer experienced in designing conventional structures on Earth in qualitatively understanding the LSS structural design process.
