PRACTICAL FIRST-ORDER RELIABILITY COMPUTATIONS USING SPREADSHEET

ABSRACT: A practical procedure for reliability analysis involving correlated nonnormals was described in Low & Tang (1997), using object-oriented constrained optimization in the ubiquitous spreadsheet platform. Numerical derivatives and iterative search for the design point were automatic. The objective of this paper is to further illustrate the 1997 procedure for two geotechnical problems with relatively complicated performance functions, namely the bearing capacity of a rectangular foundation with eccentric and inclined loadings, and the stability of an anchored retaining wall. The results are compared with Monte-Carlo simulations.
