某预应力混凝土简支梁降温法的有限元分析

Finite element analysis on the prestressed concrete simple beam with the cooling method

利用大型有限元分析软件ANSYS10.0,建立了一个工字型预应力混凝土简支梁模型,采用整体式降温法对此模型力筋进行预应力模拟,求出在徐变作用下梁体的应力和变形,从而促进预应力混凝土简支梁降温法的研究。

By using the FE software ANSYSIO. O, the text creats a I -shaped prestressed concrete simple beam modal. With the smeared cooling method, the reinforcing steel model can be given a prestressed tendons simulation, obtained the strexs and deformation under the creep of the beem, and accelerate the research of the cooling methods of pre-stress concrete simple supporting beam.
