Figure 9.11 The trapezoidal resonant model with L=50 m. Displacement hodograms in
the vertical plane at ground level (receivers (a) R5 and (b) R6) and on top of the structure
level (receivers (c) R7 and (d) R8), respectively (from Chiaruttini et al. (1996)). A shear
reasonance features the ground motion at the top of the structure.
