锚贴钢板和粘钢加固钢筋混凝土梁受剪性能的比较

Shear Resistance Properties of R.C.Beams Strengthened by Steel Plate Anchored with Rivets and by Steel Plate Bonded with Chemical Adhesive

锚贴钢板加固法是一种新型补强加固方法.本文通过对1根锚钢加固的钢筋混凝土梁和2根对比梁进行了受剪性能的试验研究.结果表明:锚贴钢板加固能够提高梁的抗剪承载力;改善梁的破坏形态;抑制梁斜裂缝的发展;且锚钢加固施工简单,施工质量容易得到保证.

Rivets anchoring steel plate is a new strengthening technique in the engineering of reinforcing and renovating of concrete structures. By comparing the shear capability of the beams strengthened by bond steel and rivets anchoring steel plate. It shows that the shear resistance of the beam strengthened by rivets anchoring steel plate is higher; that failure form of the beam strengthened by steel plate anchored with rivets is ductile ; the beam strengthened by bond steel is brittle;that the diagonal section cracks can be controlled by the steel plate anchored with rivets;that the steel plate anchored with rivets is easy to operate,and that the construction quality is easy to be ensured.
