Unformatted text preview: supported by pile group as shown in the figure.
For a seismic design analysis
of a superstructure, a
dynamic analysis using the
swayrocking model shown
in the figure is enough.
However, a structure
supported by pile
foundation requires further
calculation of dynamic
behaviors of the pile group.
The dynamic analysis
must be performed as
follows. (B) Building Foundation
Soil
Pile G.L
(F) uP ug Incident Earthquake Wave
(a) Interaction System The dynamic impedance functions and the foundation
input motion for the pile group foundation are similarly
calculated under the assumption that foundation footing or
the basement on the piles is a massless rigid body.
Performing the dynamic
analysis using the swayrocking model shown in the
figure, we obtain the total
inertial force F and the total
overturning moment M at
the foundation bottom level,
which are equal
respectively to the reaction
forces of the horizontal
KHH and...
