    摘 要:為研究聚丙烯纖維混凝土結構的受力性能,對6根不同摻入量的聚丙烯纖維混凝土梁進行了試驗研究,并利用ANSYS有限元分析軟件對其受力過程進行了非線性數值仿真模擬。研究結果表明:摻入聚丙烯纖維的混凝土梁裂縫寬度較相同條件下未摻入聚丙烯纖維的混凝土梁小,聚丙烯纖維能夠提高混凝土梁的抗裂性能;配置HRB500級鋼筋的聚丙烯纖維混凝土梁在使用階段能夠滿足《混凝土結構設計規范》(GB 50010-2010)裂縫寬度限值的要求;非線性有限元數值模擬結果與試驗結果吻合較好,該方法能夠有效地模擬聚丙烯纖維混凝土梁的受力過程。 Abstract: In order to investigate the mechanical properties of polypropylene fiber reinforced concrete structure, 6 polypropylene fiber reinforced concrete beams which have different dosages of polypropylene fiber are analyzed, and using the finite element analysis software ANSYS, nonlinear numerical simulation for the process of experiment is carried out. The results show that the crack widths of polypropylene fiber concrete beam are smaller than the unincorporated ones, the polypropylene fiber can improve the crack resistance of concrete beams. The polypropylene fiber concrete beams reinforced with HRB500 can meet to the requirements of the crack width limits of "Design Specification of Concrete Structures" (GB 50010-2010) during the using phase. And the nonlinear finite element numerical simulation agrees well with the experimental results, which indicates that this method can effectively simulate the force process of polypropylene fiber reinforced concrete beams.
