    Abstract: 鋼管抗彎構架系統中,梁柱接頭之韌性與強度為影響構架耐震性能的關鍵因素,結構耐震設計應符合「小震不壞、中震可修、大震不倒」之原則,在內橫隔板不易施作之情況下,本研究研擬以外橫隔板托梁與加勁板之組合設計梁柱接頭,藉由配置不同尺寸之可替換切削接合板於托梁與鋼梁交界處,形成消能機制以改善鋼管抗彎接頭之承載效能,研究中以一系列反覆載重試驗,評估此設計之耐震性能。研究結果顯示,此鋼管抗彎接頭在加勁板之組合作用下,因其受力面積變大,接頭承載性能穩定,不僅梁柱交會區與外橫隔板均可保持彈性,應用可替換接合板之構架,其可有效控制塑角於切削段上,構架強度亦可維持破壞模式為梁控制構架之0.8倍。另就不同寬厚比、不同之接合板而言,鋼板切削斷面有效面積越大者,其強度與消能量亦越大。上述研究結果證實,具可替換接合板之鋼管與鋼梁接合,為耐震工程之可行設計。;This study focused on the experimental evaluation of the seismic performance of modified steel tube column to wide-flange beam connections. The proposed design method combined external diaphragm, stiffened stub beam and reduced-section splice plates. A series of cyclic loading tests were conducted on the beam-to-column connections with various splice plates. It was found from the test results that connections exhibited stable hysteretic behavior during the loading process. Yielding and buckling was only observed at the reduced-section splice plates. Effective strength of the beam-to-column connections was sustained. Significant energy dissipation capability of the connections was guaranteed when splice plates with adequate dimensions were adopted. The test results justified the applicability of the proposed method to the earthquake-resistant designs.
