BFRP约束几何相似钢筋混凝土圆柱的性能研究
Research on the performance of geometrically similar reinforced concrete column restricted by BFRP
摘要
Abstract
The static compressive experiments of φ150 mm ×450 mm、φ200 mm ×600 mm,φ250 mm ×750 mm reinforced concrete columns reinforced by basalt fiber reinforce plastic (BFRP) sheet were conducted by 5 000 kN hydraulic testing machine. The results showed that restriction using BFRP sheets could increase the bearing and deformation ability of the reinforced concrete column and the limited stress increased of 84. 7 %, 85.9 % and 88. 28 % respectively. The size-effect of bearing exists for different dimension specimens. Based on the FRP strength model, the strength model of reinforced concrete column restricted by BFRP was established by modifying the parameter.关键词
