  • 早期老舊之鋼筋混凝土建築物耐震能力不足,當地震力作用時,結構物產生接頭剪力破壞和柱剪力破壞,若能準確評估結構物之破壞曲線,將進一步的掌握鋼筋混凝土結構物行為。因此本研究將用接頭剪力衰減曲線模型和理想脊柱模型進行傳統抗彎構架之層間剪力與側向位移之預測,以供結構分析工程師對於鋼筋混凝土構架行為有充分的掌握。
    由鋼筋混凝土構架實驗研究結果,發現用位移疊加之方式作為評估各梁與柱構件變形疊加成整體構架受力變形行為是可行的。在評估接頭剪力衰減部分,因忽略梁剪力變形與梁和柱端之固定端旋轉角變形影響,在預測側向位移有低估之現象產生,應需再行後續研究作探討。


    This thesis comes from an idea of seismic assessment for RC non-ductile structure. The target of the research is to provide fragility curve of moment-resisting frames with beam-column joint and base column shear failure due to earthquake loading. Estimated fragility curve of RC structure can describe failure mechanism of frames well. Therefore, a proposed joint model and an idealized backbone model were chosen to track the fragility curve.
    Comparing with four tested moment-resisting frames, predicted story shear-drift ratio curve using the concept of capacity design and superposition of displacement could express well the overall behavior of frames, especially for the excursion at the post-yielding behavior. Further study is needed when the effects of fixed-end rotation at column base and beam ends, mainly due to slippage of reinforcing steels, and beam shear deformation are considered into the predicted curves.
