The Determination of Factor of Safety against Liquefaction and Post-Liquefaction Settlement

The Determination of Factor of Safety against Liquefaction and Post-Liquefaction Settlement

This paper describes the liquefaction triggering relationships by NCEER (1997) and Youd et al. (2001, 2003), Idriss and Boulanger (2008) and Boulanger and Idriss (2014), used to assess the susceptibility of the loose sands to liquefy.

Leak-Tightness Design of Nuclear Safety Related Liquid-Containing and Buried Concrete Structures

Leak-Tightness Design of Nuclear Safety Related Liquid-Containing and Buried Concrete Structures

The objective of this paper is to provide a proposal for design of leak‐tight nuclear safety related liquid‐containing and buried structures by meshing the appropriate provisions of design, leak‐tightness and durability of the ACI 350 Code for Concrete Liquid‐Containing Structures with those of the ACI 349 Code for Concrete Nuclear Structures.
