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