| 摘 要： | 在对纤维增强材料(FRP)布约束混凝土柱破坏过程简化假设的基础上,根据弹性体体积应变理论推导出FRP布约束圆形轴压混凝土柱的强度模型,并与已公开发表的实验数据进行比较。分析结果表明,本文推荐的强度模型理论分析过程简单,其结果可以较好地适用于圆形混凝土轴压(桥)柱的加固设计,也为进一步研究FRP约束圆形混凝土(桥)柱的力学性能和承载力提供了条件。

| Abstract: | With a simplied assumption of the process of the concrete fracture,a new compressive strength model of reinforced contrete column confined by composite matetial has been deduced referring to the the theory of the unit volume change of elastic material when the RC column takes a uniaxial load.The model is also compared to published experimental datas.The results indicates that the theoretical process of model recommended here is easy to be understood and the result can be applied to the design of an FRP-wrapped RC column.The work presented here also provides a method for analyzing the mechanical performance and extreme compressive strength of the FRP-wrapped RC column. |
