CFRP加固RC双向板四点加载下中心挠度分析

Analysis on center deflection of CFRP reinforced RC two-way slabs under four point loading

对配筋相同的10块RC板进行了挠曲试验研究,试验板采用四点加载、简支支承,试验过程中考虑了贴布量、贴布方式、贴布层数、有无锚固等变化因素,分析各种贴布方式下加固板的挠度变化情况,为设计、施工及工程应用提供了有价值的参考依据。

This paper made deflection test research on 10 pieces of RC plate with same reinforcement.Test board with four point loading,simply supported.Considered in patch quantity,patch way,patch number,whether anchoring and other change factors in test,analyzed the deflection change situation of reinforcement plates with various patch ways,provided valuable reference for design,construction and engineering application.
