Reliability Analysis of Space Trusses

摘要

This paper proposes a hybrid reliability estimation technique for three-dimensional trusses used in space exploration applications. Such structures are statically indeterminate, and go through many levels of progressive damage before final collapse, under a load process. This paper combines analytical and simulation-based methods to develop an adaptive sampling technique to achieve efficient estimation of structural system reliability. The method is illustrated for application to a solar array panel mast, using a commercial finite element code.
