摘要
通过对ANSYS在体外预应力混凝土简支梁非线性分析中的应用进行介绍,并结合混凝土和钢筋的材料非线性以及结构几何非线性,建立两根体外预应力简支梁的三维分析模型,对三分点荷载作用下加载直至破坏的全过程进行分析、模拟,结果表明ANSYS能较好地模拟出受力全过程,可分析转向块对体外预应力混凝土简支梁受力性能的影响。
The method nonlinear analysis of externally prestressed reinforced concrete simple beam in ANSYS is introduced. Considering both material and geometrical nonlinearity, externally prestressed reinforced concrete simple beams are modeled and analyzed for the whole process of loading until failure at third-point loading, and compared with the experimental ones. The result shows that ANSYS can simulate the whole process of stress. The above modeling method is utilized to analyze the effect of deviator.
