低矮型鋼筋混凝土結構物之側推分析比較研究

本研究主要在探討NCREE、SERCB及FEMA三種不同塑鉸設定之建議對於不同鋼筋混凝土結構物在非線性側推分析的適用性及優缺點。側推模擬分析的鋼筋混凝土結構物試體主要包括兩部分，一是以張順益等人於內政部建築研究所進行一系列的試驗研究，其中包括一座原柱試體及兩座補強試體，另一則是以黃世建等人於國家地震工程研究中心實驗室所進行的一系列的試驗研究，其中包括兩座純構架試體及五座含牆構架試體。非線性側推分析分別採用NCREE、SERCB及FEMA三種不同塑鉸設定之建議，配合ETABS軟體進行分析並建立其容量曲線，再將三種分析結果與試驗結果做比較並比對其破壞模式。研究發現，雖然三種分析皆可模擬出近似的破壞模式，但容量曲線與試驗遲滯迴圈(包絡線)相比仍有差異，但就整體而言，仍能提供相對保守之分析結果。

The study focuses on the applications of the different definitions of plastic hinges, which were proposed by NCREE, SERCB and FEMA, for nonlinear pushover analysis. As a result, the feasibility as well as advantages and disadvantages of the definition of plastic hinge for each different proposal will be thoroughly explored and compared. In order to confirm the analytical results, the structural systems analyzed were chosen to be the specimens, which were conducted by Chang et al. (2010) and Huang et al. (200?), since the cyclic loading test results can provide actual solutions for comparison. The cyclic loading tests performed by Chang et al. include a reinforced concrete column and two identical columns, where one was retrofitted with wing walls and the other was strengthened by reinforced concrete jacketing. On the other hand, those conducted by Huang et al. content two pure reinforced concrete frames and five identical reinforced concrete frames infilled with brick wall or reinforced concrete wall. The pushover analysis was carried out by using ETABS commercial program with the definitions of plastic hinges proposed by NCREE, SERCB and FEMA. As a result, the capacity curve for each test specimen can be obtained. After comparing the analytical results to the test results, it is found that the analytical failure modes are in general consistent with test results. In addition, the capacity curve is in agreement with the envelope of hysteretic loops for each test specimen although some discrepancies exist. However, the analytical results are generally on a conservative side.
