Abstract

The compressive behavior of self-consolidating concrete columns strengthened by hybrid confinement of polypropylene fiber rope and glass fiber-reinforced polymer sheet was investigated experimentally. We cast and tested eight column specimens under axial compression load. (Six confined SCC columns and two conventional SCC columns.) The concrete grade utilized is SCC M40. For reinforcement, the SCC columns are enclosed with GFRP wrap and polypropylene fiber rope in various volumetric ratios. The compressive resistance of a confined SCC column, strength enhancement, stress-strain relationship, ductility ratio, and load deflection relationship are the parameters studied. The results are compared to establish the adequacy of the confinement. The wrapping of GFRP increases the load-carrying capacity and modulus of elasticity.

用纤维增强聚合物片材和纤维绳混合约束加固的自密实混凝土柱的抗压性能

我们通过实验研究了采用聚丙烯纤维绳和玻璃纤维增强聚合物片材混合约束加固的自密实混凝土柱的抗压行为。我们浇注并测试了八个承受轴向压缩荷载的柱试件。(使用的混凝土标号为 SCC M40。在加固方面，SCC 柱采用了不同体积比的 GFRP 包层和聚丙烯纤维绳。研究的参数包括受限 SCC 柱的抗压性、强度增强、应力应变关系、延性比和荷载挠度关系。通过比较研究结果，可以确定约束是否充分。包裹 GFRP 增加了承载能力和弹性模量。
