【摘要】 高桩码头纵横梁正负弯矩的最大值是工程设计中的控制因素,本文在分布弹性支承连续梁模型的基础上,提出宽支座连续梁跨中和支座的正负弯矩最大值的简化计算公式。对于不同悬跨比的连续梁,通过ANSYS对不同的支座相对宽度和相对刚性系数进行有限元模拟,根据数值分析结果确定公式中的系数。对某一高桩码头工程纵梁,将简化公式和有限元的计算结果进行对比,两者误差小于5%,说明简化公式具有一定参考意义。更多还原

【Abstract】 For design of high-piled wharfs,maximum value of bending moment of beams is the controlling factor.Based on the model of continuous beam with uniformly distribution elastic bearings,this paper puts forward a simplified formula for the calculation of maximum value of positive and negative moment respectively.For continuous Beam with different cantilever-span-ratio,simulations of them under different relative bearing width and relative rigidity coefficient are carried out with the Ansys finite element software.Therefore,the coefficient in the simplified formula can be determined by the simulation results.For a longitudinal beam of some high-piled wharf engineering,comparison between the maximum value of bending moments respectively calculated by the simplified formula and the Ansys shows that the relative error between them is less than 5%,which means the simplified formula is of a certain significance.更多还原
