| 摘 要： | 对实际工程中的预应力混凝土T梁进行了试验研究,从试验梁在张拉过程中的应变和挠曲变形两个方面进行了讨论和分析,建立了ABAQUS有限元分析模型并与实测值进行了对比,分析结果表明:预加力较小时试验梁的反向挠度的线形呈波浪状,预应力较大时试验梁的反向挠度的线形基本呈抛物线状。

| Abstract: | This paper made test research on pre-stressed concrete T beam in practical engineering, made discussion and analysis from the strain and deflection deformation two aspects of test beam in tensioning process, established the ABAQUS finite element analysis model and compared with the measured values, the analysis results showed ： the inverse deflection of test beam with small pre-stressed showed linear wavy shape, in- verse deflection of test beam with large pre-stressed showed linear basic parabola shape. |
