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Based on the method of limitation analysis of soil plasticity, researching from the soil arching mechanism of soil - nailing retaining, the upper limit of the critical height of soil - nailing slopes and the minimum horizontal length from coping of the potential slide surface to the edge of deep excavation are obtained through the analysis to weight of soil and vertical loading and the mechanism of soil and soli - nailing acting reciprocally
摘要基於土的塑性極限分析方法，以均質土坡為例，從土釘支護結構的準粘聚力理論出發，綜合考慮土體自重、坡頂的條形荷載，以及土釘與土體的相互作用的機理，推導出了土釘支護的臨界高度的上限值和潛在螺旋曲線滑動面在坡頂方向距基坑邊沿的最小水平距離解析表達式，可供基抗支護設計參考。In this article, idealized elastic plastic model and three - dimension finite elements programs have applied to analyzing and researching the stress and displacement distribution of 4 high - steep slopes excavated on the wan - liang expressway, and the relationship has been gained between the stress existing in excavated rock slopes and stability coefficient with depth change through the self - made fortrain program ' s application to the computation of slopes " stability coefficient ; at the same time, through the analysis of the slopes " stability coefficient, such conclusion has been gotten that cohesion in the slipping zone has important effect on slopes " stability and some proposals have been presented to improve the anti - shearing ability of the slipping body through enhancement of the cohesion in the slipping body
本文採用概化均質的理想彈塑性模型，利用三維有限元程序分析了萬梁高速公路4個高陡邊坡開挖各階段的應力及應變分佈，並且編寫了fortran程序用於邊坡穩定系數的計算，得出邊坡巖體應力及穩定系數隨著開挖深度的變化關系。並對邊坡穩定系數的敏感性進行了分析，得出滑帶內聚力的變化對邊坡穩定性至關重要，提出了改善滑帶巖土粘結狀態提高抗剪能力的工程措施。
