摘要
在墩顶点铰支撑的曲线连续梁桥设计中,选择合理的支座预偏心距来改善结构的受力性能至关重要。该文以边跨梁正负扭矩绝对值相等且扭矩最小为目标函数,采用ANSYS通用软件提供的优化设计模块和参数化设计语言(ADPL),对曲线梁桥支座预偏心的布置进行了优化设计计算。
In the design of the curve continuous-beam bridge point-hinged braced on the top of piers,it is very important to select the reasonable pre-eccentricity to improve the bearing behaviors of the structure.Taking the identically absolute value of the positive and negative torque of the side-span beam and the minimum torque as the objective function,the article uses the optimum design module and the automatic data processing language(ADPL)provided by ANSYS working software to carry out the optimum design calculation of the layout of the support pre-eccentricity of the curve continuous-beam bridge.
