本研究應用熔射覆膜技術於鋼板接合面以提升滑移係數，增加摩阻型螺栓接合強度，並探討螺栓排列對接合強度之影響。採用八顆高強度螺栓之摩阻型接合進行滑移實驗，探討螺栓在不同矩陣排列下對滑移係數、螺栓預拉力、連接板應變值及摩阻力的影響。試體採用150

In this study, thermal sprayed coating was applied to the faying surface of steel plates in order to increase the slip coefficient and enhance the slip resistance of the slip-critical joint. Moreover, this study aims to explore the effect of bolt arrangement on slip resistance. Slip tests of slip-critical connection using eight high-strength bolts were carried out to explore the effects of different bolt arrangement on the slip coefficient, bolt pretension, stress on the splice plate, and slip resistance. Splice plates of the specimens were thermal sprayed coated with 150
