Result for system with 𝑓_𝑛=0.25 Hz and 𝜉=10% considering 𝑇_𝑠=5 ms, HC=1. 𝑟=1 and 𝑑=10. (a) System eigenvalues’ moduli (maximum values) evolution with acceleration weight; (b) system responses’ (peak values) evolution with acceleration weight when subjected to type 1 seismic actions; (c) system responses’ (mean peak values) evolution with prediction horizon for different natural frequencies (𝑓_𝑛=0.25 to 1.00 Hz) for SAMPCVD, when subjected to type 1 seismic actions (10 input time accelerograms).
