解釋
桁架節點-
Space truss has developed rapidly in china and designer for its advantage has accepted the sphere soace grid. joints have play very important role in structure. generally, the weided hollow ball joints are adopted. but sometime they can not satisfy the requisition of structure. so a lot of people are busy searching for joints and fouding out all kinds of joints. a new joint - welded hollow truncated joint will be now in this paper
在我國大空間、大跨度的結構越來越多，節點在空間結構中起著重要的作用，焊接空心節點在網架、網殼等空間結構中被大量應用。本文研究的是一種新型的節點? ?焊接空心鼓形節點。 《網架結構設計與施工規程》 jgj7 - 91和《網殼結構技術規程》 jgj61 - 2003隻對空心球節點提出了承載力的計算公式，而沒有引入鼓節點。 -

The findings above confirm that there exsists three transfer mecha - nisms in the joint, that is, the truss mechanism, the diagonal strut mechanism, and the confinement mechanism
以上結果確認了節點中存在三種傳力機構，即桁架機構、斜壓桿機構和約束機構。 -
As far as the hollow inclined column - wall transfer r. c joint is concerned, the paper introduced the truss model to calculate the internal forces of transfer beam, inclined column and square column
在有孔斜柱轉換節點中引入了桁架模型以確定轉換梁、斜柱及方柱的內力。 -
On the base of the link ways of each member joint, the dissertation also puts forth a method to simplify the crossbeam bracing structure into spatial truss ， spatial stiff frame and spatial combined structure
橫梁支撐體系根據各桿件結點的連接方式，多簡化為空間桁架、空間剛架或空間組合結構。 -
The creative results are as follows : ( 1 ) behavior of the stirrup legs in the loading direction in the joint core ( along the loading direction for circular stirrups ) is different from that perpendicular to the loading direction. the stirrup legs in the loading direction acts as the tension chords in the truss model to resist shear, in the meantime, they confine the compressed diagonal strut from lateral expam - sion
沿受力方向箍肢（或部位）既作為桁架機構的拉桿參與抗剪又對斜壓桿受壓后沿受力平面側向膨脹的水平分量起約束作用；垂直受力方向箍肢（或部位）原則上僅對斜壓桿沿垂直受力方向側向膨脹起約束作用。 -
The equilibrium path is traced using the arc - length scheme with the rigid - pin - joint model in which the spatial beam elements are used in single - layer parts and spatial truss elements are used in the double - layer parts. thus the stability behavior is summarized and the critical load is obtained. 2
本文採用鋼、鉸接模型，即單層部分採用空間梁單元，雙層部分採用空間桿單元，應用弧長法跟蹤了網殼結構的平衡路徑，總結了此類網殼結構的失穩規律，並且得出了結構由單層過渡到雙層時臨界荷載的變化規律。 -
Firstly, a rigid spatial deployable truss system with joint clearance was simulated with adams
首先，對一帶有鉸接間隙的空間展開桁架利用adams進行建模模擬。 -
By comparing the ideal joint and clearance joint for the deployment process of a spatial deployable truss structure in multibody dynamics, it is found that the existence of the joint clearance makes the movement discontinuous, and also found the attitude angle degree and angle velocity of the spacecraft are affected in the deployment for the joint clearance
通過對有無鉸接間隙的剛性空間展開桁架模型的計算結果比較，說明鉸接間隙的存在對于桁架展開過程的影響及這一過程對衛星的姿態角速度的影響，同時比較了有無鉸接間隙時鉸接處在展開過程中接觸力的變化。 -
Behavior of the confinement mechamsm is also different. before obvious bond deterioration of the beam rebars passing through the joint core occurs, the shear is mainly transfered by the truss mechansim. when the bond deterioration occurs comprehensively, the shear transfered by the truss mechamism is reduced significantly, the majority of the shear is transfered by the diagonal strut
當貫穿節點的梁筋未出現明顯的粘結退化之前，節點作用剪力主要通過街架機構傳遞，斜壓桿機構傳遞的剪力和約束機構發揮的作用較小；當梁筋全面出現粘結退化以後，行架機構傳遞的剪力明顯降低，作用剪力主要由斜壓桿機構傳遞。
