vierendeel truss 中文意思是什麼
-
To meet the demands for large space and flexible compartmentation of buildings, laminated vierendeel trusses are adopted in high - position transfer story structures. first the bearing characteristics are analyzed, in which reasonable stiffness ratio of the upper chord, middle chord, and lower chord is derived. then combined with an actual engineering model ( 1 8 similar ratio ), the static loading and pseudo - dynamic tests of two models for laminated vierendeel truss used in transfer story structures are conducted, in which one model adopts reinforced concrete, and the other adopts prestressed concrete and shape steel concrete. seismic behaviors are analyzed, including inter - story displacement, base shear - displacement skeleton curves, and equivalent viscosity - damping curves. a program is programmed to carry out the elasto - plastic dynamic analysis, and displacement time - history curves of the two models are derived. the test and analysis results show that the laminated vierendeel truss with prestressed concrete and shape steel concrete has excellent seismic behaviors. it can solve the disadvantages of laminated vierendeel trusses used in transfer story structures. finally, some design suggestions are put forward, which can be referenced by similar engineering
為滿足建築物大空間和靈活隔斷要求，在高位轉換層結構中採用迭層空腹桁架結構.首先分析了其受力性能，得出了空腹桁架各構件合理的截面剛度以及布局形式.然後結合一實際工程，進行了兩榀迭層空腹桁架轉換結構模型（ 1 : 8相似比）的豎向荷載下靜力試驗以及擬動力試驗.其中一榀為普通混凝土迭層空腹桁架，另一榀配置了預應力和鋼骨混凝土，對比分析了兩模型的層間位移比、骨架曲線以及等效粘質阻力系數等抗震性能的比較，並進行了彈塑性動力分析.試驗和分析結果表明，配置預應力和型鋼混凝土的迭層空腹桁架轉換結構具有良好的抗震性能，可以成功地解決迭層空腹桁架作為轉換層結構所產生的弊端問題，最後對這類轉換層結構提出了相應的設計建議 -

通過對交錯桁架結構體系受力特點的分析，確定了在豎向荷載和水平荷載作用下交錯桁架結構體系的簡化計算模型；然後，根據計算模型，提出了豎向荷載作用下空腹交錯桁架結構的內力迭代計算方法以及水平荷載作用下交錯桁架結構的內力和側移計算方法；最後，通過分析柱端約束、同一樓層其它柱子以及相鄰樓層柱子的影響，給出了柱子計算長度系數的計算方法。 -
The paper also carried out elastic and plastic analysis on 8 - storeyed truss and 8 - storeyed vierendeel truss. based on the results, the two structures can both be applied to strong earthquake zone. however, the weak layer of the former structure is the first storey, while the weak layer of the latter is the 3rd storey
本文還對8層的混合式鋼結構交錯桁架體系、 8層的空腹式交錯桁架體系的進行了彈性和彈塑性分析，從分析結果中可以看出， 8層的兩種形式的結構都適合用於8度強震區的三類場地土區，但混合式的薄弱層是在結構底層，而空腹式的薄弱層是在結構的第3層，而且兩者的破壞模式也有所不同。 -
Failure modes of two staggered truss steel framing buildings, the results indicate the plastic hinges mainly formed in truss members, especially concentrated to the vierendeel panel. it means the vierendeel panel in the center of the truss can provide significant ductility in the structural response and the failure mode is suitable for our performance services
指出分析所得的塑性鉸分布圖中，塑性鉸大量分佈在桁架腹桿和中間空腹節間弦桿處，而柱中塑性鉸發展則很少，這樣的破壞模式符合次要構件破壞，而主要受力構件基本不破壞的抗震設計思想。
