In this investigation, MPS is implemented for three-dimensional computer models of four marginal wharves. The selected case-study structures, representative of current design practice for wharves in container terminals, are 315 m and 630 m long. Medium and soft soil conditions are evaluated for each case. The structures are subjected to sets of seven near-field records selected and scaled according to the MPS procedure. Nonlinear response history analyses are conducted and results compared against the benchmark values. The latter are defined as the median values of the engineering demand parameters (EDP) due to 30 nearfield unscaled records. The ASCE/SEI 7-10 scaling procedure is also examined for comparison purposes. It is found that the MPS procedure provides better estimates of the expected EDPs. In all cases the ASCE7-10 scaling procedure produces subestimations of expected EDPs, with errors in maximum drift and material strain demands of up to 40% and 60% respectively. Because the performance acceptance in the new standard ASCE 61-14 (seismic design of piers and wharves) is solely based on strain limits, the ASCE7-10 scaling procedure could lead to unconservative results.
