Nonlinear Response Characteristics of a Single-Degree-of-Freedom Structures Subjected to Different Earthquake Motion Types |
| Abstract |
This paper deals with nonlinear response characteristics of a single-degree-of-freedom structures subjected to recorded and artificial ground accelerations. The recorded ground accelerations that recorded in past earthquakes include characteristics of soil and region of site where those ground motions were recorded. The artificial ground accelerations are generated accordings to previous recorded ground accelerations. Each artificial acceleration has the identical phase angle to that of the original recorded ground acceleration, and has constant velocity response spectra in the range of period from 0.5 to 5.0 seconds.The seismic response analysis is mainly performed to investigate nonlinear response spectra due to different two excitation motion types, and the results are discussed. It is concluded that the artificial ground accelerations used in this study are valid to evaluate nonlinear response of building structures. |
