    Sulfur hexafluoride (SF 6) is a relatively nontoxic gas used in a number of applications for its inert qualities. The dielectric and other physical and chemical properties related to its lack of reactivity have led to the extensive use of SF 6 as an insulating medium in switching equipment (e.g., circuit breakers) by electric utilities. While SF 6

  • SAFETY OF FOUNDATIONS AGAINST LIQUEFACTION

    Liquefaction is affected by a number of factors, such as characteristics of the ground (e.g. soil properties, water table), and characteristics of earthquake (e.g. duration of shaking, peak ground acceleration). It is obvious that these factors vary horizontally and with depth. The safety of laterally extended foundations, in general, depends on:
