earticle

It is very difficult to select the appropriate input earthquake motions because it has various characteristics like as localized ground condition and the transfer route on the ground motion used for seismic design. It explains the response characteristics of input energy as performing nonlinear response analysis of SDOF depending on input earthquake wave and it compares and analyzes the input energy value when the ductility, μ is stayed form 1,2,3,4,6 in natural period of building to 0.05∼5 second. It was concluded that the simulated ground motions are applicable as input ground motions for a seismic response analysis.
