横隔板参数对装配式箱梁宽桥受力的影响
|
摘要
为了研究横隔板对装配式箱梁宽桥受力的影响以及横隔板布置参数的优化问题,建立了不同跨径、不同宽跨比的连续宽箱梁桥有限元模型,通过改变横隔板的位置、数量与厚度,考察其对中梁跨中挠度的影响,得到装配式箱梁宽桥横隔板的最优参数设置.
In order to study the influence of diaphragm on the force of assembled box girder wide bridge and the optimization of diaphragm layout parameters,the finite element model of continuous wide box girder bridge with different span and width-span ratio was established.By changing the position,number and thickness of diaphragm,the influence of diaphragm on the midspan flexure was investigated,and the optimum parameter settings of diaphragm wall of fabricated box girder wide bridge were obtained.
