| 1. | The truss comprises four plane trusses each two panels and each panel has one diagonal brace . 桁架由四个平面桁架组成,每两个节间及每个节间均有对角撑。 |
| 2. | Plane trussed lattice grids 平面桁架系网架5 |
| 3. | The actual analysis method under vertical earthquake affects about the large - span cantilever plant - truss structure 大跨度悬臂平面桁架结构在竖向地震作用下的实用分析方法 |
| 4. | The corresponding program is applied in several plane truss structures and developed to analyze space truss structures 编制了相应的程序,分析了几个平面桁架结构,并将这种方法拓展运用于空间桁架结构。 |
| 5. | Therefore , the multiport - butt of 3 - d truss , as well as the stability of turning over 2 - d truss were the difficulties of the lifting project 空间立体桁架的多对口对接、平面桁架的翻身过程稳定性是该分项工程的重点和难点。 |
| 6. | Results of illustrative examples of a six - bay plane truss bridge model are given in order to demonstrate the effectiveness of the proposed procedure 最后,用一六跨平面桁架桥模型进行数值模拟,验证文中所提方法的有效性。 |
| 7. | Yesanhe bridge is a half - through cfst arch bridges , the design of yesanhe bridge can be used for reference of adopting cfst x - type arches in the design of arch bridges with small ratio of the width to the span 野三河大桥是一座非对称中承式钢管混凝土无铰拱桥,拱肋为平面桁架形式,所以采用了x型拱肋以提高其横向稳定性。 |
| 8. | A numerical example of a ten - bar truss was given to demonstrate the validity and feasibility of cga in its application , and it is found that the optimized results of cga are superior to sga and iga 通过十杆平面桁架的数值算例来验证组合遗传算法应用的可行性和有效性,组合遗传算法的优化结果也远好于标准遗传算法和改进遗传算法。 |
| 9. | Through the analysis of receiving force performance of staggered truss frame , this paper clearly proposed the principle that nodes construction scheme should be defined according to the plane truss form for the first time 本文通过对错列桁架体系受力性能的分析,第一次明确地提出了体系节点构造应该根据平面桁架形式来确定的原则。 |
| 10. | The cfst x - type arches improve the lateral stability by sloping the arc ribs , so it is ofen used in the designs of cfst arch bridge with small ratio of the width to the span . tongwamen bridge is a half - through cfst arch bridge , its span is 238m , and the width of its roadway is 10m , so the truss ribs in - plane is sloped into x - shapc to improve its lateral stability . as the cfst x - type arches with longest span all over the country presently , the design of tongwamen bridge can be used for reference of adopting cfst x - type arches in the design of arch bridges with small ratio of the width to the span 钢管混凝土x型肋拱桥是一种利用拱肋侧倾来提高其横向整体稳定性的桥型,在宽跨比较小的钢管混凝土拱桥设计中应用较多。浙江铜瓦门大桥是一座中承式钢管混凝土无铰拱桥,跨径238m ,桥宽10m ,拱肋为平面桁架形式,所以采用了x型拱肋以提高其横向稳定性。作为国内目前跨径最大的钢管混凝土提篮拱桥,该桥的建成对我国今后长大跨径小宽跨比钢管混凝土拱桥采用提篮拱具有借鉴意义。 |
