两跨连续预应力矮肋T梁抗弯承载力分析

Analysis on anti-blending bearing capacity of two-span continuous prestressed short-lib T-beam

建立两跨连续预应力混凝土矮肋T梁模型,对模型梁进行加载试验,通过分析试验数据,得到不同荷载等级下沿梁长的挠度曲线,并取跨中截面分析跨中弯矩和挠度的关系,建立Midas有限元计算模型,发现有限元计算模型与试验结果吻合较好。

We established a two-span continuous prestressed concrete short rib T-beam model and tested it for loading. By analyzing the phenomena and data therein,the relationship between load and deflection along the beam is obtained. The results showed that the experimental results agrees well with Midas finite element calculation model we made.
