    Abstract: 國內火災事件屢見不鮮,但目前火害後鋼筋混凝土(RC)建築結構耐震能力評估模式尚付之闕如;且國內外學者專家,對於火害後RC構件之塑性鉸性質,亦未見探討。為此,本論文特別針對火害後RC構件之塑性鉸性質及火害後RC建築結構耐震能力評估模式進行深入探討。

    本論文首先收集國內外相關分析及試驗資料,探討建立火害後RC構件力學行為之簡易分析模式;再利用既有NCREE與SERCB軟體探討建立火害後RC構件塑性鉸性質之決定模式;最後綜合建立火害後RC建築結構耐震能力評估模式。

    研究成果顯示,利用本論文所建立之火害後RC梁柱構件力學行為之簡易分析模式,可簡易且合理評估火害後RC梁柱構件之殘餘強度與勁度;利用修正後之塑性鉸性質決定模式,可簡易利用NCREE或SERCB軟體合理決定火害後RC構件之塑性鉸性質;利用火害後RC建築結構耐震能力評估模式,可合理評估火害後RC建築結構之殘餘耐震能力。本文成果可供國內外工程實務界及學術界參考使用。
    There are so many fire accidents occurred in our country, but the reasonable model for assessing the residual seismic capacity of fire damaged reinforced concrete (RC) buildings structure is still lacking. In addition, the characteristic of plastic hinge of fire damaged RC members also has never been investigated by domestic and foreign scholars and experts. For these reasons, this paper is intended to investigate the characteristic of plastic hinge of fire damaged RC members and establish the reasonable model for assessing the residual seismic capacity of fire damaged RC buildings structure.
    In this paper, the analysis data and the test data produced by domestic and foreign scholars and experts were first collected and used to establish the simple model for analyzing the mechanics behavior of fire damaged RC members. The NCREE and SERCB software were then used to investigate and establish the model for analyzing the characteristic of plastic hinge of fire damaged RC members. Thereby establish a rational model for assessing the residual seismic capability of fire damaged RC buildings structure.
    The results have shown that it is easy to assess the residual strength and stiffness of fire damaged RC beams and columns by using the simple model established in this paper. As well as it is easy to use NCREE or SERCB software to assess the characteristic of plastic hinge of fire damaged RC beams and columns by using the reasonable model modified in this paper. It is also reasonabe to assess the residual seismic capability of fire damaged RC buildings structure by using the evaluation model established in this paper. The results completed by this paper will be of great use for domestic and foreign engineering practitioners and academic reference.
