Using the ground motion record that was assigned to you in Homework 1 (problem 3), compute and plot the elastic acceleration (S-T), velocity (S.-T) and displacement (S-T) response spectra for 2%, 5%, and 10% damping. Please present only three graphs as shown below, and plot the curves for each damping ratio on the same graph. Also comment shortly on the effect of damping ratio on the response spectra. S 3 curves for each damping ratio Acceleration response spectra T S 3 curves for each damping ratio Velocity response spectra Use the program SeismoSignal (or a similar package program or write your own program) for computing the response spectra. 5 curves for each local site class T 3 curves for each damping ratio Problem 2: For seismic design of a building, the following ground motion parameters are obtained at the building location from the seismic hazard map of Turkey under the earthquake ground motion level DD-2 (return period is 475 years): T Design acceleration response spectra T Displacement response spectra S. 1.091, S 0.295 Compute the elastic design acceleration response spectra for the local site classes ZA, ZB, ZC, ZD and ZE according to TEC (2018) and plot all the curves on the same graph (for T=0-3 sec). (See Chapter 2.3 of TEC). Also comment shortly on the effect of local site classes on the design response spectra. Reference: Turkish Earthquake Code (TEC) (2018). "Trkiye Bina Deprem Ynetmelii". Afet ve Acil Durumlar Bakanl, Ankara, Trkiye. Note: Use MS Excel to plot the curves (first compute the design spectral acceleration values for all critical ranges of period values). Please prepare your homework in MS Word. Make the necessary explanations, show the axis titles and units for all the graphs.
