Reinforced concrete column based on composite reinforcing layer and construction method thereof
The invention discloses a reinforced concrete column based on a composite reinforcing layer and a construction method of the reinforced concrete column. The reinforced concrete column comprises a core concrete column and the composite reinforcing layer. The composite reinforcing layer wraps the outer side of the core concrete column, and the composite reinforcing layer comprises a first restraint layer, a second restraint layer and a woven mesh reinforcing layer; the first restraint layer and the second restraint layer sequentially wrap the outer side of the core concrete column from inside to outside, and the woven mesh reinforcing layer is arranged between the first restraint layer and the second restraint layer; wherein the first restraint layer and the second restraint layer are both ECC layers doped with surface modified fibers; the woven mesh reinforcing layer is a CFRP woven mesh wrapping the outer side of the second restraint layer; the first restraint layer, the woven mesh reinforcing layer and the second restraint layer are sequentially arranged from inside to outside to serve as the composite reinforcing layer to reinforce the core concrete column, the brittleness of the core concrete column is remarkably improved, and the bearing capacity, ductility and damage resistance of the component are improved.
本发明公开了一种基于复合加固层的钢筋混凝土柱及其施工方法，包括核心混凝土柱及复合加固层；复合加固层包裹在所述核心混凝土柱的外侧，复合加固层包括第一约束层、第二约束层及编织网加固层；第一约束层和第二约束层由内而外依次包裹在所述核心混凝土柱的外侧，所述编织网加固层设置在所述第一约束层和所述第二约束层之间；其中，所述第一约束层和所述第二约束层均采用内掺有表面改性纤维的ECC层；所述编织网加固层为包裹在所述第二约束层外侧的CFRP编织网；本发明利用由内而外依次设置第一约束层、编织网加固层及第二约束层作为复合加固层对核心混凝土柱进行加固，实现显著改善其脆性，提高构件的承载力、延性和耐损伤能力的效果。
