ANSYS对预应力混凝土纯扭梁的有限元分析

Finite element analysis of prestressed concrete beam in torsion with ANSYS

在对预应力混凝土受扭构件材料的本构关系和建模方法等有限元分析理论的研究基础上,利用ANSYS有限元程序对三根不同条件下的预应力混凝土纯扭梁进行了全过程非线性分析,有限元分析的结果表明,配置与纵轴有夹角的折线式螺旋形预应力钢筋可以在不增加预应力钢筋截面积的情况下,更加有效地提高预应力混凝土构件的抗扭强度。

On the basis of the research of finite element theory,including the method of building model and the stress-strain relations of materials of prestressed concrete in pure torsion.And analyze three prestressed concrete beams in pure torsion in different conditions with Finite Element Program Ansys,illuminate configuring prestressing tendons of spiral broken lines in concrete can effectively magnify the ultimate torsion strength without increasing the quantity of tendons.It is available for reference for the e...
