研究BFRP约束钢筋混凝土方柱强度及其应力-应变关系

The Study on BFRP confined Concrete Square Column Strength and Stress-Strain Relation

分析BFRP约束混凝土方柱的受力情况,在试验的基础上,进行数据分析,阐述了影响BFRP约束混凝土力学性能的参数,分析BFRP约束钢筋混凝土方柱的强度比和含纤特征值关系,含纤特征值和峰值应变的关系,含纤特征值和极限应变的关系,得出fλ对于应力和应变都有极大的影响。

Stress analysis of BFRP confined concrete square columns,on the basis of the experiment,data analysis,elaborated the influence parameters of concrete mechanical properties of BFRP constraints,analysis of BFRP confined reinforced concrete columns with fiber strength and characteristic values,with the relationship between the fiber characteristic value and peak strain,with the relationship between the fiber characteristics value and the ultimate strain,it has great influence on the stress and strain.
