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 -
