摘要

本研究中根據國家地震工程研究中心辦公大樓等建築物在歷年來主要地震中所測得之地表加速度記錄進行動態歷時分析，以探討目前工程界採用的結構分析模式是否能掌握結構物在地震中之實際行為。研究中除將分析所得之建築物頂層加速度歷時與中央氣象局所提供之觀測資料進行比對之外，並根據建築物頂層部與底層之加速度資料，以直接積分及「區段平均值修正法」估算結構系統在地震中之變形量，以驗證結構分析結果之可靠性。

To examine the accuracy of structural analysis in typical engineering practices, linear time-history analysis in buildings such as the Administrative Building of National Center for Research on Earthquake Engineering was conducted based on ground motion records collected in previous earthquakes. In this analysis, the ground and roof accelerations of each building measured by the Central Weather Bureau were integration twice and subtracted to obtain the deformation history of roof structures during these earthquakes which was then compared to the result of structural analysis for verification.
