(b) For the given parameters of building with the initial selection of damper is given to be: m=2000 kg, = 0.15, k = 0.1x106 N/m and (ii) Fr(s) Y(s) against the frequency, Plot the absolute values transfer functions (i) with s= jo where j=1 and @= @, is the excitation frequency in rad/sec. Choose the frequency range for simulation: @= (0 0.01 29.99 30) rad/sec. X(s) Y(s) Given the amplitude of base excitation Y = Y, = 0.015 m, from the graphs find out and list the steady state amplitude X and transmitted force F, for the case of different excitation frequencies: @ =0.50, @= @ (resonance) and @=20, Summarize your observations for the vibration performance of building at different base excitation frequencies in the frequency range of simulation.
