Peak ground acceleration distribution of URBAN6-6 with respect to nondimensional spatial coordinates (1/4 FE model, , El Centro, . Structure’s location is , , , , , , , , and . The urban nondimensional width is 6.0; the nondimensional effective width of a structural group parallel to the excitation is 12.0, and the nondimensional effective width of a structural group perpendicular to the excitation is 9.0).
