摘　　要：通过对钢筋混凝土粘贴钢板后进行的静载弯曲及疲劳试验，探讨了钢板厚度、锚固措施及混凝土强度等对试件静载及疲劳性能的影响，以及在疲劳试验过程中载荷和加载线位移及跨中挠度的变化规律，总结了粘钢梁的破坏型式，并根据钢板应变分布。The effects of the plate thickness, strength of concrete and anchor measurements on the fatigue property and the mechanic properties based on the static tests of reinforced concrete beams strengthened by steel plates are compared, and modes of failure are summed up. The load deflection curves of beams and load displacement curves of beams based on the fatigue experiments of plated and unplated RC beams are presented. The differences of mechanic performance between anchored and unanchored plates are also compared according to the distribution of plate strain.
