| 摘 要： | 玄武岩纤维筋（BFRP筋）是一种性能优良的新型复合材料。为研究玄武岩纤维筋在预应力结构中的应用，运用混凝土结构非线性有限元的基本理论，利用ANSYS对预应力、非预应力玄武岩纤维筋混凝土梁进行非线性全过程计算。根据荷载挠度曲线、特征荷载值、裂缝情况等结果进行对比分析，结果表明预应力玄武岩纤维筋混凝土梁具有较高的抗裂度和刚度，而变形能力却较差；在等配筋率的情况下，极限承载力与非预应力梁相当。

| Abstract: | Basalt fiber reinforced plastics(BFRP) is a kind of new compound material with high performance.In order to study the application of BFRP tendons on prestressed force structure,first of all,the fundamental theory of nonlinear finite element method used in concrete structure is discussed in this paper.Then ANSYS is used to analyze both the prestressed and non-prestressed concrete beam with BFRP tendons.According to the results such as deflection-load curve,characteristic load value and crack condition,the pr... |
