本研究利用三維非線性有限元素程式建立標準型、蓋板補強型、側板補強型、圓弧切削減弱型、梯形切削減弱型等五種梁柱接頭試體的精確數值模型，藉以模擬五種梁柱接頭試體於火害高溫火害前後分別受到反覆載重作用下之結構行為。五種梁柱接頭試體的精確數值模型中皆加入銲道、扇形孔及背墊板後，再將普通等級的鋼材與銲材、耐火等級的鋼材與銲材受到五種溫度處理(即：未受火害、受800℃火害後空氣冷卻、受900℃火害後空氣冷卻、受800℃火害後水中冷卻、受900℃火害後水中冷卻)後於反覆載重作用下之材料參數導入各模型中，用以模擬火害前後全普通鋼、全耐火鋼及部分耐火鋼之各式梁柱接頭試體於反覆載重作用下之耐震行為。本研究的數值模擬結果顯示：精確數值模型中銲道與扇形孔的模擬較簡化數值模型更能反映出火害後梁柱接頭在反覆作用下的真實行為；假設所研究之各式梁柱接頭在原服務載重下受到800°C以上的高溫火害後均未發生大變形破壞，精確數值模型對於火害後這些梁柱接頭試體再受到反覆載重試驗之模擬的結果亦顯示：本研究所分析的所有全普通鋼、全耐火鋼及部分耐火鋼之各式梁柱接頭試體在受到800°C以上的高溫火害後水冷，再接受反覆載重試驗，皆無法通過2010年AISC耐震規範的要求，然而，前述所有梁柱接頭試體在受到800°C以上的高溫火害後氣冷，雖然所有梁柱接頭的柱面彎矩強度皆較其火害前的柱面彎矩強度為低，但皆仍能符合耐震規範的要求。

This study developed the refined three-dimensional nonlinear finite-element numerical models for five types of H-beam to box-column moment connections, including standard type connection, cover-plated connection, side-plated connection, radius-cut flange profile connection and tapered flange profile connection, to simulate the pre-fire and post-fire structural behaviors of these beam-to-column moment connections under cyclic loadings. After adding the weld passes, weld access holes and weld backings in the refined numerical models of the five types of beam-to-column moment connections, the strain hardening parameters used in cycling loadings for the normal grade steel and weld materials and fire-resistant grade steel and weld materials subjected to five temperature treatments (i.e., no heat treatment, air-cooling after reaching 800ºC for 1 hour, water-cooling after reaching 800ºC for 1 hour, air-cooling after reaching 900ºC for 1 hour, and water-cooling after reaching 900ºC for 1 hour) were utilized in the numerical models to simulate the pre-fire and post-fire seismic-resistant behaviors of the normal steel, fire-resistant steel and partial fire-resistant steel beam-to-column moment connections under cyclic loadings. The numerical simulation results showed that adding the weld passes and weld access holes in the refined numerical models reflected more realistic post-fire structural behaviors of beam-to-column moment connections under cyclic loadings than those of the simplified numerical models. Assume that all types of beam-to-column moment connections, originally subjected to service loads, considered in this thesis did not fail due to large deflection after the fire with high temperature above 800ºC. The results from the refined numerical models of simulating these post-fire beam-to-column moment connection specimens to be tested by cyclic loadings showed that, after subjected to the fire of or above 800ºC and then water-cooled to room temperature, all the normal steel, fire-resistant steel and partial fire-resistant steel beam-to-column moment connection specimens analyzed in this thesis could not meet the 2010 AISC seismic-resistant requirements. However, after subjected to the fire of or above 800ºC and then air-cooled to room temperature, all the previously mentioned beam-to-column specimens could still meet the seismic -resistant requirements with the decreased column face flexural strengths.
