Reliability Evaluation of Double-Layer Spherical Lattice Shell

Article Preview

Abstract:

Reliability and sensitivity of double-layer spherical lattice shells are extensively investigated, moreover the effect of different types of random variables and different positions of random variables on reliability and sensitivity are also studied in detail. External loads, cross-sectional area and yield strength of members are defined as random variables respectively according to their types and layouts in the lattice shells, and their effects on sensitivity are substantially calculated. Effect of random variables on several performance functions is also studied. Finally, correlations among these performance functions are calculated.
