本文根據黃震興等人於國家地震工程研究中心所進行之ㄧ座縮尺三層兩跨鋼筋混凝土(RC)純韌性抗彎構架(PMRF)及另一含RC牆之相同抗彎構架(WMRF)之振動台試驗結果進行非線性動力歷時分析與驗證。振動台試驗分為兩個階段,第一階段先測試RC純抗彎構架,其後再測試含RC非結構牆之抗彎構架,試驗採用Tap100、Tcu078、Tcu017等三筆地震加速度歷時資料,依次放大倍率,分別量測頂層、3樓、2樓之相對最大位移及絕對最大加速度動態反應。本研究在理論分析部份,係依據宋裕祺等人所建議之構材塑性鉸特性設定方法,再配合Takada遲滯模式,設定對應的構材非線性元素特性,並利用SAP2000進行整體結構非線性動力歷時分析,分析所得各樓層之地震反應與實驗成果頗為吻合,本文所得結果,冀能供為工程師參考之用。
This paper extends the authors’ previous study on the pushover analysis of reinforced concrete (RC) column to the present nonlinear time history analyses of the RC frame structures. Shaking table tests of one scaled-down RC pure moment-resisting frame (PMRF) structure and the other identical one with RC wall additionally (WMRF) were served as the data-base in verifying the accuracy of the analytical results. It shows that the simulated seismic responses at each floor of the frame structures appear to be in a good agreement to the experimental results. The results obtained might help the promotion of the precision in nonlinear time history analysis of the RC structure.
