鋼筋混凝土結構之鋼框架補強分析

Abstract

921大地震中，低矮型鋼筋混凝土結構物遭受了極大的損害，顯示國內長久以來，低矮型建築的結構耐震設計較常被忽視。而921大地震之後，業界人士與專家學者陸續提出許多經濟且有效的耐震補強方式，其中包含了利用鋼框架補強鋼筋混凝土結構。本研究提出一套以鋼框架補強鋼筋混凝土結構之簡易分析方式，並與先前鋼框補強試體之實驗數據結果互相比對，來驗證本研究所提出的簡易分析方式結果是否保守且合理。接著利用本研究所建議的分析方式，選定國內某棟舊校舍為示範例，評估以鋼框架補強後之耐震能力。本研究所建議的簡易分析方式，希望能提供給工程師以簡便且保守的方式來評估鋼筋混凝土結構以鋼框架補強之耐震能力。

In September 21, 1999, the Chi-Chi earthquake caused devastating casualty, Low-rise RC structures are damaged so seriously that seismic design for low-rise RC structures had been neglected obviously. After September 21, 1999, the Chi-Chi earthquake, industry and experts made way that is a number of seismic reinforcement of economic and efficient. Which includes the use of RC structures retrofitted with steel frames. This research focuses on a set of simple analytical methods of RC structures retrofitted with steel frames , and compare with the previous experimental data of RC specimens retrofitted with steel frames. Which to verify that are conservative and reasonable. Then use the recommended analytical methods in this study, selected a domestic buildings of the old school for the demonstration example, to assess the seismic capacity of reinforced steel frame. Simple analytical methods suggested in this study, hoping to provide engineers with a simple and conservative approach to evaluate the seismic capacity of RC specimens retrofitted with steel frames. Keywords: retrofitted with steel frames, Simple analytical methods, RC specimens retrofitted with steel frames, seismic capacity RC structures.
