端部大樑
英文
end girder-
The conclusion of reappearing analysis is that crane bridge be used as usual because main weld maximum stress of upper cover plate of main beam lower than yield limit though it higher than permissible stress. inner stress of secondary beam was over ultimate strength, and deforming is ultra big. so it was unfit for produce and secondary beam must be changed
再現分析得出的主要結論為：橋架的主樑上蓋板主焊縫的最大應力超過了許用應力，但小於屈服極限，可以繼續投入使用；副梁內部的應力遠遠超過了強度極限，變形特別嚴重，不能滿足生產要求，因此更換新的副梁；端梁內部的應力超過了屈服極限，小於強度極限，在應力較大的位置焊接補強板；投入使用后，要對整個橋架進行定期檢查。This device takes rubber ( plastic cement ) as substitute for metal bumper, inside it an inflated tyre is set, ineffective part joining front of supporting frame and bumper is removed, and replaced by metal connecting bar, bar front is fixed unto bumper, and bar ' s rear connected with spring, spring ' s rear is fixed to a steel bowl firmly hugging closely an inflated rubber ball ( two ), rear ball is closely hugged by another steel bowl at front of another spring, and another rubber ball placed at spring ' s rear
該裝置由橡膠（塑膠）代替金屬保險杠，內置充氣胎，去掉前端大樑與保險杠連接的無效部分，以金屬連杠代替，連杠前端固定於保險杠上，後端連接彈簧，彈簧的後端固定一鋼碗緊貼充氣皮球（兩個） ，后皮球與另一彈簧的前端鋼碗緊貼，另一彈簧的後端再放置一充氣皮球。The top beam can reform the force - bearing mechanism of the retaining piles because the cantilever piles can be fixed by adding a restriction on the top of the piles and the displacement of the piles can be reduced too. as the same time, top beam can harmonize the displacement and force of the piles and avoid the phenomenon of chain failure as one of the piles is destroyed. if the top beam are closed it can work well because the support on the two ends
樁頂圈樑對支護樁的作用主要體現在：改善支護樁的力學性狀，變懸臂樁為頂端約束的超靜定狀態；對樁頂位移起限製作用，減小基坑工程對周邊環境的不良影響；協調各樁之間的受力和位移，避免局部受力過大引起各樁之間的連鎖破壞現象。The following principles are proved : increasing cfp adhesive length will release the concentrating of shear stress near the cutoff point, this will lead to the increment of loading - bear capacity of concrete beams ; increasing the thickness of cfp will improve the transition of load from concrete beam to cfp, this is useful to exert the potential of cfp ; in creasing the anti - shear modulus of adhesive will result enhance the concentrating of shear stress, this is harmful to the effect of cfp reinforced concrete beams
本文的理論分析結果可以表明：增加碳纖維板的粘結長度可以緩解碳纖維板端部界面上的剪應力集中，改善混凝土梁結構的加固效果；增大碳纖維板的粘結厚度可以增大界面上的剪應力，改善混凝土樑上載荷向碳纖維板的傳遞效果，有利於充分發揮碳纖維布的潛能；如果粘結膠層的抗剪模量過大會加劇剪應力的集中，從而對碳纖維加固的效果不利。分享友人
