Assess the liquefaction hazard at the footing of the building at this site

 

A multistory building is to be built on a level ground at a seismically

active site. The SPT is performed during the subsoil exploration phase.

A safety hammer is used, and the outside diameter of the modified

California sampler used is 3 inches. The peak ground horizontal accel-

eration that was recorded in the seismic history in this area is 0.2 g,

and the design earthquake magnitude is 6.5. The mat foundation is

designed to be 8 m below ground where the fine content is 15%. At

8 m depth, the soil sample is retrieved by the sampler. The blow counts

at the first, second, and third six-inch penetrations are 8, 9, and 8,

respectively. The boring log indicates the following subsurface profile.

Explain why attenuation is not a big problem in PET.

Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….
