Write down the formulations of piecewise linear exact method together with the formulations of recurrence
relations and coefficients hand written formulations on A size plain paper
Develop an Excel sheet to compute dynamic response of a linear elastic single degree of freedom SDOF
system. Use piecewise linear exact method formulations presented in lecture notes. Time histories, that you
are asked to compute and plot, are listed below;
Displacementtime history,
Velocitytime history,
Accelerationtime history,
Pseudo Accelerationtime history,
Total Accelerationtime history.
Compute dynamic responses of SDOF systems with natural vibration periods of and for
Centro NS sampling rate: sec units:g earthquake ground motion record for damping ratio of For
the SDOF system, having natural vibration period of repeat your analysis for different damping
ratios of and
In each of your graphs, point out the peak response. Compare the differences in responses of SDOF
systems and comment on how peak responses are affected by damping ratio.
Compute pseudo acceleration response spectrum and displacement response spectrum for Centro
NS earthquake ground motion record with damping ratios of and There will be two graphs;
each of them shall include response spectrum values for three damping ratios. Compare your results and
comment on response spectrum characteristics.
