| Abstract |
Nonlinear time history analyses are frequently carried out for performance-based seismic design. In order to carry out these analyses, the
selection of appropriate seismic waves is very important. Since no seismic wave data of the design spectral acceleration level existed in
Korea, the seismic wave data of the PEER Center is generally used. However, many of seismic waves selected from the PEER Center
seismic wave selection system tend to have predominant short period. Therefore, this study proposes a seismic wave selection method with
various predominant periods from the PEER Center seismic wave selection system. This paper introduces the current building seismic criteria
for design seismic wave selection and the PEER Center seismic wave selection system, and is investigated the maximum response
acceleration distribution using the PEER Center seismic wave selection system and the proposed seismic wave selection method. As a result,
the maximum response acceleration of the PEER Center seismic wave selection system was distributed in a specific range of predominant
period, and no significant difference of the spectral accelerations was found in before and after the site response analyses. On the other hand,
the proposed method was properly distributed in various predominant period domains, and the predominant periods maintained almost the
same values after the site response analyses. |
