摘要
利用有限元数值分析方法,对静载作用下的碳纤维钢筋混凝土梁开裂性能进行分析。通过有限元数值模拟方式,利用逐渐增大荷载的方法,分析碳纤维含量对梁体开裂性能的影响。通过与普通钢筋混凝土试件模拟结果相比表明,碳纤维钢筋混凝土梁具备更好的开裂性能。其裂缝宽度可通过普通钢筋混凝土梁的规范公式进行修正。
This paper analyzed the cracking behavior of carbon fiber reinforced concrete beam under static load using the finite element numerical analysis. By the way of finite element numerical simulation and the method of increasing the load gradually to analyze the carbon fiber content influence on the beam cracking. By comparing with the simulation result of common reinforced concrete beam test piece, it turned out that the carbon fiber reinforced concrete beam has a good cracking and deformation behavior. Its crack width can be revised by the common reinforced concrete beam rules.
