| 摘 要： | 研究拉压预应力混凝土梁模型梁的试验结果,数值模拟对梁全过程的工作状态.研究结果表明：预压钢管能有效对混凝土施加预压应力;在一定范围内,高预应力度的拉-压预应力混凝土梁的弹性性能更优越,承载力发挥较好;预压钢管的作用可以代替部分预应力钢绞线的作用;钢管端部锚固区域的混凝土出现应力集中,设计、施工中加强此处的构造措施.

| Abstract: | A tensile-compression prestressed concrete model beam is presented with a numerical simulation of beam performance whole process analysis. Research results shows that the pre-compression steel pipe can offer concrete effective pre-tension stress; elastic properties and bearing capacity are more superior for high pre-stress degree this tensile-compression prestressed concrete beam within limits; the effect of pre- compression steel pipe can be used as partial prestressed steel strand; The end anchorage zone of this pipe meets the concrete stress concentration, which shall be strengthened in the Engineering design and construction. |
