| 摘 要： | 对于城市高架桥常用的双柱花瓶式桥墩,其平面杆系模型难以准确计算系梁横向受力,结果往往偏于不安全。采用ANSYS实体有限元模型进行计算,并根据应力迹线绘制"撑杆-系杆体系"简化模型,分析各参数对横向系杆力的影响,并给出一种简便的计算方法。

| Abstract: | For the double-column vase-shaped pier commonly used in the urban elevated bridge,its 2-D member system model is hard to correctly compute the transverse stress of bowstring beam.The result is often insecurity.The article uses ANSYS solid finite element model to compute it,and draws the simplified model of "brace strut-bowstring system" based on the stress trace so as to analyze the influence of various parameters on the transverse bowstring force and to give an easy computation method. |
