| 摘 要： | 通过建立钢筋钢纤维混凝土既有裂缝梁和钢筋混凝土既有裂缝梁的有限元分析模型,借助ANSYS分析了两种梁在荷载作用下的裂缝尖端处应力、裂缝宽度增幅和挠度并作出对比。分析结果表明钢纤维对裂缝开展有很好的阻止作用,而且能明显缓和裂缝尖端处应力,减小梁的挠度。

| Abstract: | The finite element analysis models are built to analyze the steel fiber reinforced concrete beam with crack and reinforced concrete beam with crack. Using ANSYS,this paper analyzed the stress at the tip of cracks, the increment of crack width, and the flexibility of two kinds of beams under load. The stress at the tip of cracks, the increment of crack width and the flexibility of beams are also compared. The results show that the steel fiber can not only effectively prevent the crack expanding, but evidently alleviate the stress at the tip of cracks and diminish the flexibility of beams. |
