[提要] 為研究粘鋼加固對構(gòu)件剛度的影響,通過試驗對不同形式的粘鋼加固梁在短期荷載作用下的破壞形態(tài)進行觀察和分析;結(jié)合鋼筋混凝土梁的相關(guān)理論,提出粘鋼加固構(gòu)件在短期荷載作用下的剛度和撓度計算公式。計算結(jié)果表明理論計算值與試驗值吻合較好,可供粘鋼加固設(shè)計參考。
[關(guān)鍵詞] 粘鋼加固 剛度 撓度In order to study the impact of rigidity of R.C.beams by gluing steel plates,the break appearance of different R.C.beams strengthened by gluing steel plates under short-dated loading is observed and analyzed through experiment.With theories of R.C.beams, the referencing formulas to calculate the rigidity and deflection under short-term loading on R.C.beams reinforced with steel plate are proposed. The results show that the calculating results cohere to the experimental results well, which provide a reference for the design of gluing steel plates.
Keywords: reinforced with gluing steel plate; rigidity; deflection參 考 文 獻
