针对混凝土收缩徐变对预应力混凝土梁长期服役性能的影响,本文利用《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004)给出的徐变公式与ANSYS显式徐变相结合,利用温度变化模拟混凝土的收缩作用,计算得到考虑徐变与不考虑徐变效应的预应力梁长期挠度值,建立预应力梁收缩徐变效应分析方法。 In view of the influence of concrete shrinkage and creep on the long-term serviceability of prestressed concrete beams, this paper uses the creep formula given by the Code for Design of Bridges and Culverts of Highway Reinforced Concrete and Prestressed Concrete (JTG D62-2004) to combine with the explicit creep of ANSYS, Using the temperature variation to simulate the shrinkage of concrete, the long-term deflection of prestressed beams considering creep and without considering creep effect are calculated to establish the analysis method of shrinkage and creep of prestressed beams.
