横张预应力砼梁关键部位受力性能研究

Study on behavior of the concerning regions of the vertically tensioned prestressed concrete beam under load

横张法预应力混凝土属于后张有粘预应力混凝土结构,预应力钢筋张拉有别于常规后张法施工。本文利用ANSYS软件对横张预应力混凝土梁在张拉施工阶段的受力情况进行仿真模拟,研究粘结锚固区域和插销定位区域混凝土受力变形的规律,为横张预应力混凝土结构设计和施工提供参考。

The vertically tensioned prestressed concrete is a new construction technology.It is the stick post-tensioned prestressed concrete structures,but different from conventional post-tensioned prestressed in the construction details.The vertically tensioned prestressed concrete beams in the tension phase of the situation was simulated by software ANSYS.The laws of concrete regional deformation in both adhesive anchor position and bolt position were studied.The results can provide the reference for the design and construction of vertically tensioned prestressed concrete.
