对受压区侧面粘钢混凝土梁进行了静力试验，试验中测量了不同集中荷载作用下的钢筋混凝土梁在不同配筋率、不同粘钢截面面积时的跨中挠度。考虑粘贴钢板的作用，将受压区粘贴的钢板换算成混凝土，得到一个T形截面，给出了考虑粘贴钢板作用的混凝土梁短期刚度计算方法。讨论了集中荷载、配筋率和粘钢截面面积等因素对受压区侧面粘贴钢板的钢筋混凝土梁短期刚度的影响。

The static tests of the RC beam with steel plate pasting on its side on compressive zone are carried out. And the mid-span deflection of RC beams with different reinforcement ratio and sticking steel sectional area are measured under different concentrated load. Then considering the role of pasting steel plate, the steel plate is converted to concrete to get a T-shaped section. Thus the calculating method of short-term stiffness of concrete beam considering pasting steel plate is put forward. Finally the effects of relevant factors such as concentrated load, reinforcement ratio and sticking steel sectional area on the short-term stiffness of RC beams pasting steel plate on its side on compressive zone are discussed.
