Peak ground acceleration distribution of URBAN6-6 with respect to nondimensional spatial coordinates (1/4 FE model, , , El Centro, . The structure location is , , , , , , , , and ). The urban nondimensional width is 6.0, the nondimensional effective width of a structural group parallel to the excitation is 8.0, and the nondimensional effective width of a structural group perpendicular to the excitation is 7.0.
