the buried,

concrete-arch structures of PLUMBBOB
Project 3.1. The Equivalent Surcharge method, which
assumes failure at the threshold of the compression
regime, appeared to be the most suitable for the design
of structures located above the ground-water table
regardless of the direction of the blast front. For
structures located below the ground-water table, the
Uniform Compression Mode was the most suitable. A method
of predicting radiation transmission for use in the
design of buried structures is given. Procedures and
sample calculations for the design of footings, floor
slabs, and end walls are presented in Appendix A. Sample
calculations for the response of a specific arch under
each of the loading methods are presented in Appendix B.
Appendix C presents results of a study to establish the
ductility factor at the threshold of the compression
regime. 13 references.
