解釋
雙向梁-
Fabrication of the box beam is divided into such parts as reinforcement, formwork, concreting, prestressing, moving and storing of beam, pipe grouting under pressure, end sealing of the beam, water - proof layer on the bridge surface system, protective coating etc. the paper makes description of effective box beam construction technology and workmanship which can be adopted in other projects, such technologies as : manufacturing and fixing of reinforcement, steel reinforcement fixing baseplate, web plate and top plate respectively and lifting the steel skeleton into form, requirements of design and manufacturing and way of utilization for dismantling - erection type formwork and hydraulic formwork, optimization of concrete ratio, concrete pouring process of two ends of beam in priority over the middle, in sequence of first baseplate followed by web plate and top plate at last, concrete pouring in inclined section and in horizontal layer, concrete vibration mainly by external vibrator in assistance with internal vibrator, methods and regulation for steam curing of concrete, dual controls over stress and strain to ensure quality of prestressing workmanship, construction method of effective beam moving by heavy - weight special moving facility, some regulations and key notes about construction of grouting under pressure, beam ends sealing, water - proof layer on the bridge surface system, protective coating
箱梁製造由鋼筋工程、模板工程、混凝土工程、預應力工程、移存梁工程、孔道壓漿工程、梁體封端工程、橋面防水層和保護層工程等施工環節組成。文中介紹的採用胎具製作和綁扎鋼筋，分底腹板和頂板分別綁扎並吊裝鋼筋骨架入模；拆裝式和液壓式兩種模板的設計、製作要求和使用方法；綜合考慮、優化混凝土配合比，混凝土灌注從兩端至中間、先底板、后腹板、再頂板的施工順序和斜向分段、腹板水平分層、附著式振搗為主、插入式搗固為輔的施工工藝，蒸汽養護的方法和規定；應力應變雙控制確保預應力施工質量的施工技術；採用重物移運器有效移梁的施工方法；壓漿、封端、橋面防水層和保護層施工的一些規定和注意事項等都是對箱梁製造行之有效的施工技術和施工方法，並可為以後類似施工作借鑒。 -
In this paper, the three level fortification criterion, two stage design method and the elastic response spectrum theory are adopted, and the program of nba ( the program of nonlinear - aseismic analysis for beam bridge ) is used to calculate. through gathering, analyzing and calculating a lot of bridge design materials, this paper induces a simple way to calculate the relative displacement of the beam and the pier, and then according to the current design method, it concludes a better design principle of the supporting length of the beams. at the same time the dynamics is adopted to put forward the design method of the carrying capacity and the lengthen of prestress wire ( steel bar ) falling - off prevention structures of highway bridges
本論文採用三水準設防、兩階段設計方法、彈性反應譜計算理論，運用橋梁結構非線性地震響應分析程序nba （ theprogramofnonlinear ? aseismicanalysisforbeambridge ）進行計算；通過收集大量的實橋設計資料，經分析計算，歸納總結出計算上下部結構相對位移的簡便計算方法；並綜合國內外的經驗值，提出梁的支承長度se的設計原則；同時運用動力學突加荷載的原理，推導分析了預應力鋼絞線式（鋼棒連接式）落梁防止裝置設計承載力的計算方法和設計伸長量s _ f的取值；最後本文通過實橋計算，說明了落梁防止系統設計的方法。 -
The one - way slab, two - way slabs, principal and subordinate - beam structure, non - beam structure and the grid - beam structure are putting into use in the reinforced concrete slab
鋼筋混凝土樓（屋）蓋結構大都採用單向板、雙向板、主次梁結構、無梁樓板以及井字梁結構等。 -
Based onthe analysis of the behavior of joints, further analysis about the composite steel frame isproceeded. in this way, the stiffness matrix of the frames is inferred, and the formula of thefixed moment calculation about beam element with semi - rigid connections is presented. at theend of this paper, a two - span and five - story composite steel frame is analyzed using finiteelement software ansys8. 0. the analysis indicates that the semi - rigid behaviour of joints havesome influence on the mechanical behavior of frame, but the main factor of influence is the
最後採用ansys對一雙跨五層組合鋼框架進行了結構分析，分析表明，連接節點的半剛性性能對組合鋼框架的受力性能有影響，但半剛性組合鋼框架的受力性能的主要影響因素是節點約束系數，本文詳細分析了約束系數對框架受力性能的影響，指出在組合鋼框架設計當中，考慮連接的半剛性性能能使框架內力分配更為合理。
