My question is that going by the definition of time period that is, "the time required to complete one oscillation". Now, if I say the best option for an engineer should be that , the building should not oscillate , am I right? That could happen if the time period of a system is very large, right? Because, if the time period is LESS, the frequency is MORE, hence the system would suffer more oscillations , right?So to make the building suffer no oscillations/ less oscillations the time period should be LARGE. SO AM I RIGHT IF I SAY LESS STIFFNESS AND MORE MASS WOULD BE THE IDEAL CONFIGURATION?
