Helpful yung mga videos mo sir. Especially yung Response spectrum analysis na discussion mo using the software. Nagkakaidea na kami as students about seismic design. Thank you sa effort ng pagdiscuss I hope na marami pa kayong maturuan.
That is a great explanation. I like it, sir. But I have one question. can we choose any mass and stiffness value to get maximum responses, or are there any recommended natural periods that we can use to collect maximum responses of the system for each damping ratio? with regards!
Yes, we can graph all the different periods of vibration vs the maximum responses (e.g. acceleration, velocity and displacements) this is what we call the response spectrum curves (RSC) We use RSC for response spectrum analysis (RSA). Most earthquake codes uses a damping ratio of about 5% Responses are a function of the period/frequency and the damping ratio in RSC.

Can I have your excel file sir? About the elcentro earthquake using newmarks method?
what are the formulas for k* , a1, a2 and a3 ?
