摘要
文章以实际工程为研究背景,用MIDAS有限元软件对整体式斜交板进行建模分析,并依据计算分析结果,从斜交板的受力特征对支座布置的影响、加载不同的支座约束模拟边界条件对支反力计算结果产生的不同影响、斜交板的配筋注意事项和斜交板的受力特点对桥梁下部墩台结构布置产生的影响四个方面,提出了斜交板桥梁设计工作中应注意的相关事项。
With practical engineering as research background,this article used the MIDAS finite element software for the modeling analysis of integral inclined plate,and based on the results of calculation and analysis,it proposed the related precautions in the design work of inclined plate bridge from four aspects,i.e.the impact of force characteristics of inclined plates on the bearing arrangement.Different im-pact caused by loading the different bearing constraints simulation boundary conditions on the support reactions calculation results,bar-reinforcing precautions of inclined plates,and the impact generated by the mechanical characteristics of inclined plates on the pier structure arrangement at lower part of bridges.
