| 摘 要： | 针对宽跨比较大的整体简支板桥,分析现今常用横向分布计算方法原理的近似与局限。选取3组不同宽跨比桥梁,依不同桥面布载分5种工况建立ANSYS有限元实体模型。分析模型数据与常用横向分布计算方法之间的结果差异,提出了一套适用于整体板桥的内力简化计算模式。

| Abstract: | Aiming at the integral simple supported slab bridge with large width-span ratio,the approximation and limitation of the calculation principle of transverse distribution commonly used nowadays are analyzed.Three bridges with different width-span ratio are selected,and five kinds of ANSYS finite element entity models are established according to different deck-load conditions.A reasonably simplified calculation model of internal force of integral simple supported slab is put forward by analyzing the difference between the results got by model and those got by transverse distribution calculation method. |
