摘要: A previously introduced method for transmitting effective seismic excitation to a discretized soil-structure system implemented. The permits free-field of linear soil be specified within the regie computation, arbitrarily close zone that includes (possibly non-linear) structure and local subgrade bae, thus eliminating need transmit through artificial boundaries. This approach is demonse numerical example comprising linear, two-dimensional system. Some comments also are made on rere efficiencies various absorbing
