[提要] 为研究粘钢加固对构件刚度的影响，通过试验对不同形式的粘钢加固梁在短期荷载作用下的破坏形态进行观察和分析；结合钢筋混凝土梁的相关理论，提出粘钢加固构件在短期荷载作用下的刚度和挠度计算公式。计算结果表明理论计算值与试验值吻合较好，可供粘钢加固设计参考。

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
