摘要
预应力钢—混凝土组合结构作为一种组合横向构件 ,能充分发挥钢材的抗拉强度和混凝土的抗压强度 ,具有承载力高、刚度大、延性好、节省材料等优点。设计了两根两等跨的连续预应力钢—混凝土组合梁 ,通过对它的实验研究 ,取得预应力对裂缝宽度、挠度的影响 ,并通过有限元软件分析 ,得到预应力钢—混凝土组合连续梁具有更好的弹性 。
As a kind of transversal composite element,the advantages of prestressing steel-concrete composite beam result from full utilization of two materials.Therefore,Two beams that are two spans continuing beam are designed and tested.The effect on deflection and fracture according to prestressing is considered.By the finite element analysis,the research shows that prestressing can reduce fracture and deflection and get better elastic behavior.
