Summary:	目前美國(AISC 2010)與台灣的設計法規不建議高強度螺栓摩阻接合與銲接併用,但日本(AIJ 2012)設計規範並無相關限制。本研究使用前人實驗資料進行分析探討併用接合變形能力。與日本規範建議之螺栓滑動變形0.2mm比較後發現,分析的45組試體皆有發生滑動變形,且半數以上變形能力大於銲接接合變形能力。螺栓與銲接併用接合強度為個別接合強度加總的0.9倍,對照之下兩向銲接接合的強度略大於銲接個別強度加總的0.9倍。強度安全係數分析依(AISC 2010)現行規範統一進行計算螺栓與銲接個別強度,再參照日本(AIJ 2012)建議併用強度為螺栓滑動強度加上銲接強度,再跟併用接合試驗結果進行比較。結果安全係數最大2.75,最小1.23,分析119組平均值為1.92。 As suggested by AISC (2010), Taiwan steel design regulations do not recommend slip-critical high strength bolts to use with fillet welds. No similar restrictions are set by AIJ (2012). This paper evaluates the deformation capacity and strength of slip-critical high strength bolts in combination with fillet welds. AIJ suggests that bolts may have sliding deformations of 0.2 mm. The analyzed 45 joints were found to have deformations greater than the sliding deformation, and even greater than the fracture deformations of fillet welds. The joint strength were found to approximate to 90% of the sum of bolt sliding strength and weld fracture strength. The percentage is slightly smaller than that for transvers and longitude welds. The nominal values of bolt sliding strength and weld fracture strength were calculated using AISC formula, and were then summed up to calculation the joint strength as suggested by AIJ. The ratio of test to calculation was taken as the factor of safety (S.F.). The S.F. values of the 119 analyzed joints were found to have a maximum of 2.75, a minimum of 1.23, and an average of 1.92.
