接力式繫筋由兩支短繫筋分別連接於箱型柱對側組成,過去的短柱軸力試驗顯示接力式繫筋可以有效圍束箱型柱外圍混凝土。為了獲得更直接的資訊來印證接力式繫筋的有效性,本次試驗規劃柱試體之撓曲試驗,探討含接力式繫筋試體撓曲韌性發展的性能與特性。本研究試驗參數為柱板寬厚比,使用之寬厚比為37以下,根據分析及實驗結果作以下結論:
彈性分析結果顯示:(1)在彈性階段內,有效繫筋的勁度是與寬厚比有關的。
實驗結果顯示:(1)接力式繫筋為有效設計;(2)接力式繫筋圍束混凝土的功能與直通式繫筋相似;(3)包覆填充型箱型柱之韌性行為,基本上不受柱板寬厚比的影響;(4)為了保守起見,輔助縱向鋼筋的直徑不得小於橫向鋼筋間距之1/6。
Previous short column tests show that the so-called combined tie is able to provide noticeable confinement to the outskirt concrete. in this study, encased concrete-filled steel box column specimens are tested under prescribed cyclic loading to investigate the effectiveness of the combined tie on the ductility of the encased concrete-filled box columns. Width-to-thickness ratio is the main parameter in this study, base on the test results, the ratio is proposed to be smaller than 37:
Elastic analysis results shows that: (1) In the elastic region, the stiffness of the combined ties is related to the width-to-thickness ratio.
Experimental results shows that: (1) Combined tie is effective to be used in the design.(2) In providing confinement to concrete, the combined tie has a similar function to the tie used in the reference specimen. (3) In this experiment, the ductility of concrete-filled steel box columns is not significantly affected by the width-to-thickness ratio. (4) For a conservative design, the diameter of supplementary longitudinal reinforcement must not be smaller than 1/6 times the hoop spacing.
