摘要(中) 本研究探討老劣化鋼筋混凝土受震行為，主要探討鋼筋腐蝕之老劣化，鋼筋混凝土試體進行加速腐蝕試驗以加速其老劣化，並藉由老劣化試體與對照組試體同時進行振動台實驗，振動台實驗結果顯示老劣化後之試體其加速度、位移反應大於對照組試體，顯示腐蝕效應造成之老劣化現象對結構確有損害。
本研究亦建立數值分析模型，依實際鋼筋混凝土試體之尺寸、材料及加速腐蝕試驗之結果建立原始模型與腐蝕模型，並進行動力歷時分析，將其分析結果與振動台實驗結果進行擬合，擬合結果顯示加速度與位移歷時圖之波形大致相符，驗證數值模型之可靠性。
最後將分析模型進行側推分析與非線性歷時分析，探討腐蝕效應對結構物之影響，並提供未來實驗方向參考。
摘要(英) The research is aimed to discuss the seismic response of the aging reinforced concrete. The major object is discussed with the degradation of corroded reinforcement. Accelerating corrosion test is applied to accelerate the aging effects, and shaking table tests is conducted to compare dynamic responses of the aging specimen and normal specimen. By comparing the responses, the experimental results show that the acceleration and displacement responses of the aging specimens are larger than the normal specimens. The results reveal that corrosion effect of the aging effects damages the construction.
The research also builds the numerical models which are according to the sizes, materials of the real specimens. The modeling the corrosive effect of the specimens is according to the results of accelerating corrosion test and calculating the parameters by formulas. The dynamic time history analysis of the finite element analysis is conducted after the models are built. By comparing the results of shaking table test and the results of analysis, the comparing results reveal the acceleration and displacement responses are coincide well. It proves that the reliability of the numerical models. At the end of the research, the pushover analysis and nonlinear time history analysis are applied to discuss the corrosion effect of the construction and provide the experimental aspects for the future researches.
