摘要:
对粘钢补强钢筋混凝土(RC)梁在荷载作用下的变形过程和破坏形式,进行了理论和试验研究,讨论粘钢位置和粘钢量对RC梁的短期刚度、挠度、开裂荷载、极限荷载和破坏形式等承载性能的影响.通过理论计算结果与试验结果的比较分析,得出粘钢板与RC梁协调工作系数主要随相对高度变化的结论.提出计算协调工作系数、抗弯承载能力和挠度的计算公式,给出工程设计建议和确定合适钢板宽厚比、粘钢位置和粘钢量的技术措施.
Abstract:
The deformation and failure modes of reinforced concrete(RC) beams strengthened with bonded steel plates are investigated theoretically and experimentally.It’s discussed the influence of bonded steel position,area and quantity on short-tern stiffness,deflection,cracking load,ultimate load and failure modes of RC beam.Comparing the theoretical results with the experimental ones,it’s concluded that the co-worked coefficient of bonded steel plate and RC beam varies mainly with the relative depth of compression zone.The formulas to calculate co-worked coefficients,flexural bearing capacity and deflections are put forward.The design suggestions and technical measures to determine the suitable width-to-thickness ratios,positions and areas of bonded steel plate are also presented.
