为了更好的使GFRP筋替代传统钢筋作为受力筋放在混凝土梁结构中,必须对其受力性能进行全面的研究探讨,文中借用大型有限元软件ANSYS对四根不同工况的混凝土梁进行了模拟分析,其中包括三根GFRP筋混凝土梁以及一根传统的钢筋混凝土梁。详细讲解了利用ANSYS建模过程中的重点与难点,最后也应用该软件得出了不同工况下GFRP筋混凝土梁配筋率对梁裂缝分布的影响,以及极限荷载作用下GFRP筋的所承受的极限应力和梁跨中挠度。
In order to make the GFRP tendons replace the traditional tendons as the tendons placed in the concrete beam structure, we must conduct a comprehensive study of the mechanical properties of the GFRP tendons. In this paper, we use the finite element software ANSYS to carry out four concrete beams with different working conditions The simulation analysis, including three GFRP tendons and a traditional reinforced concrete beam. The key points and difficulties in the modeling process of ANSYS are explained in detail. Finally, the software is used to get the influence of the reinforcement ratio of GFRP tendons under different working conditions on the distribution of beam cracks and the bearing of GFRP tendons under the ultimate load The ultimate stress and mid-span deflection.
