1)  space truss element
空间杆元
1.
In this paper, with the application of the catenary cable element and space truss element and nonlinear FEM method, the problem can be effectively solved by controlling the variation original length of cables instead of the design tension.
本文采用悬链线索元、空间杆元模型和几何非线性有限元理论 ,利用索原长变化量和索张力一一对应的关系 ,进行了分批张拉预应力的分析。
2)  space bar element
空间杆单元
1.
By the method of transforming the node DOF of the space bar element to the node DOF of the space virtual laminated element,that is,the node of bar element need not fixed on the node of space solid element,the prestressed concrete structure were simulated together.
通过自由度变换,把空间杆单元的节点自由度用空间虚拟层合单元的节点自由度来表示,即杆单元的节点无需固定在体单元节点上,共同模拟了预应力混凝土结构。
2.
By the method of transforming the node DOF of the space bar element to the node DOF of the space solid element,the position and direction of prestressed reinforced needn\'t be taken into account,that is,the node of bar element needn\'t be fixed on the node of space solid element.
通过自由度变换,把空间杆单元的节点自由度用实体单元的节点自由度来表示,使得单元网格划分不必考虑预应力钢筋的方位,即杆单元的节点无须固定在实体单元节点上,共同模拟了预应力混凝土结构。
3)  spatial curved lever unit
空间曲杆单元
4)  finite element of spatial frame structure
空间杆系有限元
5)  space member system element finite model
空间杆系有限元模型
1.
The paper introduces the characteristics of the second storey rigid bridge of Quzhuang Interchange in Guangzhou City and establishes space member system element finite model for making the static and dynamic analysis to provide the theory basis for design.
简单介绍了广州市区庄立交第二层刚架桥的特点,并建立了空间杆系有限元模型,对其静力、动力进行详细分析,为设计提供理论依据。
6)  Spatial Finite Element Method of Bar System
空间杆系有限元法

【诗文】:
数岁平津邸,诸生出门时。羁孤力行早,疏贱托身迟。
芳草看无厌,青山到未期。贫居悲老大,春日上茅茨。
卫玠琼瑶色,玄成鼎鼐姿。友朋汉相府,兄弟谢家诗。
律合声虽应,劳歌调自悲。流年不可住,惆怅镜中丝。
