hi guys, i am really new on matlab thats why i need some help :)
(a) Calculate and plot the following spectra for 2, 5, 10 % damping using only North-South NS components of records provided to you. 1. Sa 2. Sv 3. Sd 4. PSA=wn2Sd (b) Calculate and plot PSA/Sa ratio for each damping as a function of Tn. (c) Compare the 5% damped Sa normalized with respect to PGA, with the Code Spectral shape for the associated site characteristic. (d) Compare the 5% damped Sa with the Code Spectra, seismic zone 1 for the associated site characteristic. (e) Discuss the results obtained above.
here is the quetion.. i need to compute this program in matlab and instructor gave me some values..but i dont have any idea how to compute.. who wants to help? :) i will be glad too much..
