【摘要】 为了研究纤维增强复合材料(FRP)约束混凝土棱柱体的轴压性能,采用碳纤维布(CFRP)和玻璃纤维布(GFRP)对其进行包裹,研究纤维布约束混凝土棱柱体的力学性能,分析其承载力的变化以及应力—应变的关系。试验研究表明:FRP对混凝土棱柱体具有良好的约束性能,经约束后的混凝土棱柱体的承载能力大幅提高且变形性能得到改善。更多还原

【Abstract】 In order to do a study on the axial compression behavior of confined concrete prisms that have been strengthened with FRP sheets, the carbon fiber reinforced composites and glass fiber reinforced composites were used. And the mechanical properties of concrete prisms were studied. The results show that fiber reinforced composites can constrain the effective of concrete prisms, the load carrying capacity of the concrete prisms repaired and strengthened would increase largely.更多还原
