预应力混凝土梁挠度计算研究

Study on deflection calculation of prestressed reinforced concrete beam

预应力混凝土构件受力是钢筋与混凝土相互作用的结果。为得到准确的构件挠度计算公式,文章建立了物理模型和基于ANSYS有限元软件的数学模型,并进行了仿真分析。结果表明,ANSYS有限元模型和物理模型的数据与改进的挠度公式吻合较好。

The force of prestressed concrete member is the result of interaction between reinforcement and concrete.In order to get an accurate deflection formula of the components,physical model and mathematic model using ANSYS program were established in this paper.Then the simulation analysis was carried out.It shows that the result obtained by the improved deflection formula is in good agreement with those obtained by the physical model and the mathematic model.
