Table 2.3.2 DESIGN DATA FOR HI-STORM UMAX ISFSI Value (minimum or Type nominal, as Comment applicable)

Strain compatible effective This space may be remediated with

8. 485 ft/sec minimum shear wave velocity in Space vertical reinforcement such as C, V pilings to enhance V.

Strain compatible effective This space will typically contain native

9. shear wave velocity in Space 485 ft/sec minimum soil.

D, V (Figure 2.4.4)

Top of the Grade Horizontal and vertical spectra shown in (Ground surface) Figures 2.4.1 and 2.4.2 are based on 5%

spectra per Figure damping.

2.4.1 with Following the Newmark 100-40-40 horizontal ZPA, aH and response combination technique [2.6.7]

vertical ZPA, aV endorsed by the Regulatory Guide 1.92 scaled as follows: [2.4.7], the resultant ZPA for a 3-D earthquake site is defined as: aR=

aH = 1.0g a1+0.4a2+0.4a3, where a1, a2 and a3 are

10. Design Basis Earthquake aV = 0.75g the sites ZPAs in three orthogonal and foundation surface directions and a1a2a3.

pad spectra per Figure Hence, the DBE resultant ZPAs at 2.4.2 with horizontal ground surface and foundation surface ZPA, aH and vertical elevations are ZPA, aV of:

1.3 gs (=1.0x1.0gs + 0.4x0.75 gs) and aH = 0.93g 1.214 gs (=1.0x0.93gs + 0.4x0.71 gs),

a = 0.71g respectively.

V Permissible long-term Used as the input value in the strength
