反復(fù)彎剪對高強度螺栓端板連接節(jié)點抗滑移性能影響*
——輕型薄壁鋼構(gòu)件高強度螺栓端板式連接系列研究之三
陳以一 楊永華 韓 琳 沈祖炎 (同濟大學(xué)土木工程學(xué)院 上海200092)[提要] 報告了反復(fù)彎剪荷載下高強度螺栓摩擦面采用醇酸鐵紅處理的端板式連接節(jié)點的試驗結(jié)果,并與單
向靜力彎剪荷載下的連接性能進行比較分析。結(jié)果表明,對低抗滑移系數(shù)的高強度螺栓端板式連接,反復(fù)加載后的承載性能與單調(diào)加載時基本相同。
[關(guān)鍵詞] 低抗滑移系數(shù) 高強度螺栓 端板連接 節(jié)點性能 反復(fù)荷載試驗Test results of end plate joints with high-strength bolts connection and a certain rust inhibiting coatings under repeated moment and shear force are reported. The behaviors of the same joint under monotonic loads are compared. It is shown that for this kind of joint in the feature of low friction factors, their behaviors under repeated load are almost the same as those under monotonic loads.
Keywords: repeated load test; end plate connection; high-strength bolts; joint behavior參 考 文 獻
