Resumo: | ||||||||
Situations involving structure-soil-structure interaction using SASSI 2000
and ACS SASSI protocols are concerned. Initially, techniques of elastic plane
waves propagation in solids are used to understand SASSI free-field solution
algorithm. Then, in SASSI scenery, some relevant properties of the model are
varied and their influence on the interaction is analyzed. These parameters
include: soil-main structure fundamental frequency ratio and between adjacent
structures, structures mass relation and relative distance and embedment,
between the main and the satellite structure. The responses are visualized
trough SASSI 2000 acceleration transfer functions obtained in the central node
of the top of the main structure. It is also proposed a new way of response
visualization: the structural mechanical viscoelastic compliance, defined as the
system ability to catch mechanical energy form the ground excitation and to
keep it under a viscoelastic deformation state. It is suggested as a preliminary
analysis stage to evaluate the influence of the satellite system in the main
system response. A preliminary study on ground motion spatial variation using
the ACS SASSI, version 2.2, protocol is also presented. One compares the
influence of this consideration in the free-field solution, when the incoherence
models available in the protocol are used. A couple of guide learnings and
suggestions are left to the reader.
