| 摘 要： | 利用Ansys有限元软件建立了在单调荷载作用下钢筋混凝土梁的模型,在对未加固梁和碳纤维布加固梁的开裂荷载、极限荷载与相应实验结果对比的基础上,分析了加固梁在不同荷载下纤维布和混凝土的应力变化,模拟了两种梁的裂缝分布和开展规律。结果表明,Ansys模拟加固混凝土梁的开裂荷载和极限荷载与实验值的最大误差为10.2%,碳纤维布的工作过程与实际相吻合,裂缝的分布及开展也符合试验现象。

| Abstract: | With finite element model of Ansys software,the model of reinforced concrete beam is established under monotonous loads.At the basic of cracking and ultimate loads between Ansys calculate value and experimental ones,the stress changing of Carbon Fiber Reinforced Plastic(CFRP) and concrete are analyzed at different loads.The cracking and development rules are also simulated.The results show that the maximum error of Ansys calculate values and experimental ones is in 10.2%,function of the CFRP conform to experimental ones,the distribution and development of crack also accord with experimental ones. |
