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But at present, the static performances of the double reticulated domes applied on the different load combination of wind load, snow load, live load, seismic load and dead load are not adequately studied. also the study on the dynamical response under seismic action is not sufficient
但目前對于這類空間結構在雪載荷、風載荷、恆載荷、活載荷、地震載荷等各種載荷共同作用和各種載荷分佈方式下的靜力性能研究還不充分，特別是對其在地震作用下的動態響應的研究還不足。According to construction features of three - span prestressed concrete and continuous rigid frame box with v pier bridge, the paper demonstrates the shell finite element theories, c onstruct the spatial model, and researches its spatial stress and variable regularity under different loads including uniform load, concentrated load and prestressing force wire. morever, the paper studies vibratory modal of three - span prestressed concrete and continuous rigid frame box with v pier bridge, and sets about experimental investigation of the corresponding practical bridge
本文根據典型的三跨預應力混凝土墩連續剛構橋的特點，提出採用板殼有限元法計算理論，建立其空間分析模型，研究該橋在不同荷載（均布恆載、集中活載、預應力束）支承條件下的空間受力特性和變化規律：探討了典型三跨預應力混凝土墩連續剛構橋的空間靜動力特性及相應的振動模態；探索一般的平面理論預測值與實際空間效應的差異，並進行相應的試驗研究。The initial strain must be the optimum value obtained by multiple - trial method. 5. in the static analysis of the bridge model under live load, assuming a shifting concentrated load on the girder, analyzing the relation map of each section deflection and the location of the concentrated load, finishing the load - on of the worst - case live load, then the moment and deflection envelope diagrams of the girder were obtained
成橋模型建立后，在後續活載作用下的靜力分析必須首先在主樑上作用移動集中荷載，分析主梁各斷面的活載撓度與集中荷載作用位置關系曲線圖，完成最不利活載的加載，從而最後得到懸索橋主梁的彎矩包絡圖及撓度包絡圖。In formerly static strength tests, no attention was paid to the process of test load. according to their experiences, experimenters adjusted pressure in actuator only by hand to control the test load value and the load value was read from instruments
早期的靜力試驗對加載過程沒有嚴格的要求，所以當時的液壓加載方式由試驗人員直接調整供油壓力，改變液壓缸內的油壓，控制活塞桿輸出的集中力載荷。分享友人
