摘要
针对钢筋混凝土框架结构抗震加固问题的复杂性 ,本文深入分析了抗震加固结构的受力特征 ,探讨了卸荷对加固构件承载力的影响 ,并针对抗震加固后的“隐含危险转移”问题提出了相应的对策。最后 ,提出了抗震加固的基本原则 。
The problem of seismic strengthening of R.C.frame is very complex.In this paper, the author analyses mechanical characters of structure strengthened,discusses th e effect to load capacity of members strengthened when the loads applied on them are unloaded.According to the problem of “hidden danger shift” for the struct ure strengthened,corresponding countermeasure is given.Basic principles of seism ic strengthening for R.C.frame are given also;these are appreciated for referenc e in seismic strengthening of R.C.frame \
