中文拼音 [xièzǎigǎn]
卸載桿
英文
discharge arm-
In this test, a special bolt - jack is used to exent of prestressing force to brace angles as the whole structure is under dead - load. in this state brace angles withstand partly load before twice - load and the stress and strain of concrete are decreased. in this way the aim of removal of load and strengthening can be reached
本試驗中採用專用螺栓千斤頂在恆定荷載水平下對混凝土柱角鋼撐桿施加預壓應力，使外包角鋼在二次受力前即分擔部分荷載，使混凝土應力水平和應變水平降低，達到卸載與加固同步進行的目的。Brief introduction the model kx920 wheel is one of the series leading products made in our works that is well received both at home and abroad for its reaso - nable design, beautiful contour, and advanced norms. by adopting of three - ele ment torque converter, fixed - axle type pcwer shifing transimission box, in = bub reduction, double - axle drive, hinged frame, all hydraulic steering, and clamping brade. the loader has such features as : large power reseve, fi - neaccelerating performace, comfortable operation, wide field of vision, it " s muti = function, high - effic ient and flexible engineering machinery. mor - eover, it can be equipped with many kinds of working attachments such as flat fort, muti - fnction bucket, and snow plow, so it may be used for loading and unloading, transporting, piling and leveling materials in various kinds of projects. mines, enterprises and city. welcome friends both at ho - me and abroad to visit our factory and to order our products

物流臺車又稱載物臺車；表面採用電氣鍍鋅、外形美觀、使用壽命長；附安全皮帶、固定桿裝卸速度快，既便於機械化搬運，又宜於短距離的人力移動，可實現規劃生產，節省人力，降低成本；與周轉箱等物流容器配合使用，可實現單元化管理，置物空間大，折疊收藏不佔空間；適用於企業工序間的物流搬運；也可在工廠或配送中心裝上貨物運到商店，直接作為商品貨架的一部分。The main work of this paper was as fellows : ( 1 ) generalized the development of pre - stressed steel structure in our nation and abroad, and pointed out the main problem in practice ; ( 2 ) presented the mechanism of pre - stressed steel structure and revealed its applicable range ; ( 3 ) established the optimization design model for pre - stressed steel structure, which accounts for constraints on stresses and displacements of structure ; ( 4 ) brought forward the optimization design method, which combined linear programming and the principle of full restriction, through which we can obtain the magnitude of each time pre - stress and the optimized sections of each members of structure ; ( 5 ) analyzed the best times of pre - stress and pointed out that 2 ~ 3 times is preferable ; ( 6 ) conducted optimization design on large - space steel roof, horizontal parallel steel truss with local cables, horizontal parallel steel truss with global cable, and ultra - static steel truss, the result of which indicated that the multiple pre - stress structure is very economic ; ( 7 ) compared different schemes of cable placement for horizontal parallel steel truss, and the results showed that the local cable only unloaded the second girders, but had no response on the first girders and stomach poles, while global cable could unload the second girders and the stomach poles outside of turning point of cable, thus proving that global cable is more economic than local - cable
本文的主要工作是：對國內外預應力鋼結構的發展歷史及現狀作了綜述和總結，指出當前預應力鋼結構工程實踐中存在的主要問題；闡述了預應力鋼結構的受力機理，並指出預應力鋼結構的適用范圍和特點；在考慮結構應力和變位約束的條件下，建立預應力鋼結構優化設計模型；提出多次預應力鋼結構優化設計方法和步驟，採用線性規劃和滿約束準則相結合的優化方法，可優化設計出施加的每一級預應力的大小，並得到結構各部分的優化截面；對多次預應力最佳的施加次數作了分析，並建議以2 3次為宜；為驗證文中理論和方法，分別對大跨多次預應力鋼屋架、局部布索的水平平行弦鋼桁架、整體布索的水平平行弦鋼桁架和局部布索的超靜定鋼桁架等算例進行了優化設計，經濟效益明顯；對水平平行弦鋼桁架的幾種施加預應力的方案進行比較，對于局部布索，預應力只對下弦起到卸載作用，對上弦和腹桿基本不起作用；而整體布索預應力除對下弦卸載外，對索折點以外部分腹桿也起到卸載作用，經濟效益好於局部布索。分享友人
