| 摘 要： | 以常德达门船舶有限公司吊机码头工程为例，建立多个框架码头三维有限元模型，在分析研究变刚度多层框架码头承受不同位置船舶水平撞击力下的变形特性的基础上，通过对比有无竖向斜撑、水平斜撑等方案对码头整体变形的影响，提出增加竖向斜撑而不增加水平斜撑的优化方案。该优化减少了复杂荷载条件下框架码头结构的变形，在有限的工程投资下，增加了结构的整体性，提高了结构的可靠度。

| Abstract: | Taking Changde Damen crane wharf (a variable stiffness frame wharf) project for example,we establish several frame wharf three-dimensional finite element models.After analyzing and researching the deformation characteristics of variable stiffness frame wharves under different working conditions that ship percussive horizontal force is impacted at different water levels,we compare different overall deformations of frame wharves with or without vertical diagonal bracing and horizontal diagonal racing,and optimize the frame wharf structure by setting vertical diagonal bracings without setting horizontal diagonal racings.The optimized structure not only decrease the overall deformation of the frame wharf under the complex load condition,but also strengthen the frame wharf structural integrity and structural reliability with a reasonable cost. |
