Comment

8.

Strain compatible effective shear wave velocity in Space C, V 485 ft/sec minimum This space may be remediated with vertical reinforcement such as pilings to enhance V.

9.

Strain compatible effective shear wave velocity in Space D, V (Figure 2.4.4) 485 ft/sec minimum This space will typically contain native soil.

10.

Design Basis Earthquake Top of the Grade (Ground surface) spectra per Figure 2.4.1 with horizontal ZPA, aH and vertical ZPA, aV scaled as follows:

aH = 1.0g aV = 0.75g and foundation surface pad spectra per Figure 2.4.2 with horizontal ZPA, aH and vertical ZPA, aV of:

aH = 0.93g aV = 0.71g Horizontal and vertical spectra shown in Figures 2.4.1 and 2.4.2 are based on 5%

damping.

Following the Newmark 100-40-40 response combination technique [2.6.7]

endorsed by the Regulatory Guide 1.92

[2.4.7], the resultant ZPA for a 3-D earthquake site is defined as: aR=

a1+0.4a2+0.4a3, where a1, a2 and a3 are the sites ZPAs in three orthogonal directions and a1a2a3.

Hence, the DBE resultant ZPAs at ground surface and foundation surface elevations are 1.3 gs (=1.0x1.0gs + 0.4x0.75 gs) and 1.214 gs (=1.0x0.93gs + 0.4x0.71 gs),

respectively.
