（浙江省建筑科學(xué)設(shè)計(jì)研究院 杭州 310 012）[提要] 通過11根混凝土強(qiáng)度等級為C14的簡支梁試件在集中荷載作用下的試驗(yàn)研究，得到外粘整塊鋼板后梁的受剪承載力。隨粘鋼規(guī)格的不同，粘鋼混凝土梁發(fā)生不同的破壞形態(tài)。根據(jù)試驗(yàn)結(jié)果，建立了粘鋼部分承擔(dān)的受剪承載力理論計(jì)算公式和受剪斜截面限制條件。
[關(guān)鍵詞] 外粘整塊鋼板 混凝土梁 抗剪 加固Based on the experimental study of eleven simple-supported RC beams with externally bonded steel plates under the concentrated load,the shear load capacity with concrete strength grade C14 is obtained. The failure circumstances of the beams with externally bonded steel plates are varied with their dimension. According to the test results,the computational formula of the shear load capacity about the externally bonded steel plates and the restricted condition of oblique shear section are set up.
Keywords: externally bonded steel plate; shear load capacity; reinforcement concrete beam
