the foundation are calculated. Then, the dynamic impedance matrix is given by: (15)
that is, the dynamic impedance matrix is given by
inverse matrix of the displacement matrix.
The cross terms KHR and KRH in the dynamic impedance
matrix are trivial for the foundation when the embedding
depth is shallow. The response of the massless foundation due to the
earthquake disturbance is calculated, the lateral response
Δ and the rotational angle Θ are the foundation input
motion of the horizontal and the rotational component,
respectively. The figure shows the dynamic
analysis model for the
superstructurefoundationsoil
interaction system ( coupling
system).
In this model, the foundation
assumed to be rigid is
supported by the horizontal
KHH and the rotational KRR
dynamic impedance functions
and the foundation input
motions Δ and Θ are applied at
the outside of the impedance
functions. Building KHH Foundation KRR Δ Θ
