短跨梁
英文
short beam-
For reinforcement concrete corbel with the shear span to depth ratio ( a / ho ) less than 1, has its performance of mechanics that is close to cantilever deep beams, it is an important kind of components in architectural structure which sustains roof trusses, brackets, tray " beams, frame " beams, wall " beams and crane " beams
剪跨比a h _ 0 1的短鋼筋混凝土牛腿，其受力性能接近於懸臂深梁，在建築結構中是支承屋架、屋面梁、托架、托架梁、框架梁、墻梁和吊車梁等的重要構件。Stumps were inserted and welded between the two straddles so that the girders become an integrated arched girder
變異拱高低跨連接處採用短柱焊接，形成一個完整的鋼拱梁。Abstract : based on the systematic analysis of the shear behavior for r. c. beams, the tests of 11 simple supported beams under the top concentrated loads and the uniform loads are supplemented. the prime variable is shear span ratio, span depth ratio, horizontal web reinforcement ratio and vertical web reinforcement ratio. according to the test results, the working behavior, the prime shear failure modes, the effect of concrete and web reinforcement ( horizontal web reinforcement and vertical web reinforcement ) and other aspects of r. c. beams are analysed. the uniform calculation method for shear capacity of deep beams, short beams and shallow beams for practical is presented
文摘:在對國內外鋼筋混凝土梁的受剪性能進行較系統分析的基礎上，補充了11根鋼筋混凝土簡支短梁在頂部集中荷載和均布荷載作用下的試驗，試驗梁的主要變化參數為剪跨比、跨高比、水平腹筋率和垂直腹筋率.根據試驗結果，對試驗梁的工作性能、主要的剪切破壞形態、混凝土項的抗剪作用、抗剪腹筋（包括水平腹筋、垂直腹筋）的作用等進行了較為深入的分析，提出了可適用鋼筋混凝土深梁、短梁和淺梁相互協調的受剪承載力的統一計算方法For example, the large friction loss of prestressed tendons, complex anchorage bearing joint, the problem of cracks in large area structure, axial compress of long span continuous beam under prestress. all those hinder its use in long span structure. until now days, the cognition about the behavior of such structure under loads is not enough for the realm of prestressed concrete of all the world
但是，預應力技術應用於大跨連續框架結構，在設計和施工中還存在一些缺點和不足，例如預應力筋的摩擦損失過大，節點錨固區設計和構造復雜、大面積結構的裂縫控制問題、大跨框架梁在預應力作用下的軸向縮短等，這些都是困擾大跨預應力混凝土框架結構應用的突出問題，特別是目前對于預應力混凝土超靜定結構的受力性能，國內外預應力界的認識尚不夠全面。Bridge with high pier and long span uses high - strength materials and thin - wall structure and often adopts segmental construction method, the effect of concrete elastic modulus and creep and shrinkage are significant, so aging stability analysis research has important significance
又由於此類橋梁大都採用節段施工方法，施工周期短，混凝土的彈性模量變化、徐變收縮等時效因素的影響顯著，開展大跨徑混凝土橋梁施工全過程穩定性研究具有重要意義。The techniques of cast - in - situ concrete box girder by movable formwork bridging machine, which is a railway erection crane for bridge made up by universal rods, are effective, reliable and can use the exiting road for opporation
摘要採用萬能桿件等常規材料拼裝的軌道走行式移動模架造橋機，能利用既有道路進行高架橋現澆箱梁施工，且工期短、效率高、安全可靠，適宜於城市輕軌交通中等跨度雙線預應力混凝土筒支箱梁的現澆施工。In ordinary circumstances, the height of the grid - beam is about the 1 / 16 of the short span
一般情況下，井字梁的高度約為短向計算跨度的1 16左右。分享友人
