基于有限单元法的T梁横隔板布置形式分析研究

Analysis and Research on the Arrangement of T-Beam Diaphragm Based on Finite Element Method

横隔板在装配式T形梁桥中起着保证各根主梁相互连接成整体的作用,它的刚度愈大,桥梁的整体性愈好,在荷载作用下各主梁就能更好地共同工作。以40 m跨预应力混凝土连续T梁为例,分别对其横隔板正交布置与斜交布置进行受力计算,通过差异分析研究其对T梁整体受力性能的影响,为桥梁设计提供一定的借鉴和参考意义。

The transverse diaphragm plays a role in ensuring that the main beams are connected to each other in the assembled T-beam bridge.The greater the rigidity,the better the integrity of the bridge.Under the load,the main beams can be better.work together.In this paper,a 40 m span prestressed concrete continuous T-beam is taken as an example,and the orthogonal arrangement and oblique arrangement of the transverse diaphragm are respectively calculated.The influence of the transverse force on the overall force performance of the T-beam is studied by differential analysis,which provides the bridge design.Certain reference and reference significance.
