| 本文提出分析斜拉桥的索膜单元理论,建立起索膜单元概念与计算模型,推导出索膜单元刚度矩阵,说明了用索膜单元分析斜拉桥的方法细节,应用索膜单元对144+360+144米公路钢斜拉桥方案进行了分析计算,得出了主梁弯矩影响面与扭矩图,讨论了索梁锚固点与截面水平主惯性轴偏心对主梁弯矩的影响。 |
| 英文摘要: |
| The cable-membrane element theory used to analyse the cable-stayed bridge is proposed in this paper. The concept of the cable-membrane element and its computing model is constructed, and the stiffness matrix of the cable-membrane element is derived. As an example, a steel cable-stayed bridge(144+360 + 144m) is computed using the method proposed. The bending moment influence surface and torque graph of the main beam is obtained, and the influence of the eccentricity of the anchored-joint of cable-beam to the main horizontal inertia axis of the cross section on the bending momentof main beam is also discussed. |
