摘　　要：碳/玻混杂纤维增强塑料(HFRP)筋具有弹性模量高、造价低的特点,受到工程界广泛关注。完全采用试验方法研究碳/玻混杂纤维筋混凝土梁的抗弯性能,往往成本较高。本文在试验研究的基础上,应用ANSYS软件对HFRP筋混凝土梁的抗弯性能进行有限元分析,计算结果与试验结果吻合较好,从而为HFRP筋混凝土的推广应用提供了一条便捷的研究方法。Carbon/glass HFRP bar attracts great attention in the civil engineering structures for its high elastic modulus and lower cost. It is expensive by experimental research on behaviors of HFRP bars reinforced concrete. Based on the test results, flexural behaviors of HFRP bars reinforced concrete beams are analyzed by ANSYS software. The results of FEM analysis and experiments are identical well. It provides useful method for researching the application of concrete beams reinforced with carbon/glass HFRP bars on civil engineering.
