Effects of a Group of High-Rise Structures on Ground Motions under Seismic Excitation

Figure 20

Peak ground acceleration distribution of URBAN2-2 with respect to nondimensional spatial coordinates (1/4 FE model, , El Centro, . The structure location is . The urban nondimensional width is 2.0; the nondimensional effective width of the structural group parallel to the excitation is 5.0; the nondimensional effective width of the structural group perpendicular to the excitation is 3.0).
