Question 7.8: Construct a response spectrum for the symmetric triangle sho......

Structural Dynamics of Earthquake Engineering: Theory and Application Using Mathematica and Matlab [1014074]

Construct a response spectrum for the symmetric triangle shown in Fig. 7.24a. Plot DMF vs td/T in the integral 0 ≤ td/T ≤ 10. Assume ρ = 0, td = 2 s.

A MATLAB program for drawing response spectrum is given in Chapter 6.

The response curve is shown in Fig. 7.24b.

A family of response spectrum curves or response spectra can be produced for a specific load case by evaluating response maxima for several values of damping ρ. Hence maximum response of a linear SDOF to a specified time depends on $\omega_{ n }$ and ρ.
