Outrigger - braced structures as a modification of framed - tube structures is widely used in high - rise buildings , for it has a outstanding merit to improve the lateral stiffness , reduce the floor displacement and lessen the moment of the tube . many theories on this aspect have been put forward 在高層、超高層框架?筒體結構中設置水平加強層,是提高結構的抗側剛度,減小結構在水平荷載作用下的樓層位移,降低筒體彎矩的有效手段,在實際工程實踐中得到了廣泛應用。

Based on this theory , the thesis conducts a space dynamic analysis on a framed - tube structure that has different belted outrigger plans . the main contents of the analysis are listed out as below : ( 1 ) on the basis of the fea theory , uses the general fea software ansys to set up a structure model 本文依據此理論,對一框架?筒體結構,按不同的加強層設置方案,進行了空間有限元動力分析,做了以下幾方面的研究: ( 1 )采用大型通用有限元分析軟件ansys ,依據有限元理論,選取合適的單元模擬結構各構件,建立起結構有限元分析模型。

Through the powerful stuucture anslysis ability of ansys , the thesis creats the fea models of carrier frame , outriggers and pins seperately and has them combined . the carrier frame structure “ s intensity is analyzed . nonliner contact analysis is applied to the contact position of carrier frame , outriggers and pins 論文對ansys軟件進行了簡要的介紹,然后充分利用ansys強大的結構分析和接觸分析功能,采用把車架、支腿和銷軸分別建模,再把它們組合在一起的方法,對底架結構進行強度分析,對車架、支腿和銷軸接觸處進行非線性接觸分析。

The computing results of the thesis shows that qtjs 160t railway crane ' s carrier frame has met the intensity requirements . the local stress of the contact position of carrier frame , outriggers and pins is presented . the dangerous positions of the carrier frame are pointed out 論文分析、計算結果表明, qtjs160t鐵路起重機底架結構滿足強度要求,論文給出了車架、支腿和銷軸聯接處的局部應力情況,指出車架在回轉支承圈處存在應力集中部位。

Then , gives suggestions on seismic design of the outrigger - braced structures . ( 4 ) from the results of the seismic analysis , try to probe the rule that how the belted outrigger works to reduce the displacement and improve the lateral stiffness ( 4 )在對結構進行抗震動力分析的基礎上,通過具體詳細的定量分析研究,總結設置加強層對結構內力分配的影響規律,探討水平加強層減小結構側移、提高抗側剛度的機理。

He would be away , in the south seas , building his grass house , trading for pearls and copra , jumping reefs in frail outriggers , catching sharks and bonitas , hunting wild goats among the cliffs of the valley that lay next to the valley of taiohae 他要到南海去,去修建他的草墻房屋,去做珍珠和椰子干生意,會駕駛帶平衡翼的獨木船在礁石間出沒,捕捉鯊魚和鯉魚到泰歐黑山谷附近的峭壁上去打野蘋。

The pacific archipelagos of fiji and tonga have for centuries been connected by trade and kinship : tongan princes sailed westwards in outrigger canoes to seek fortune in fiji , while fijians provided spouses for the tongan nobility 數百年來,太平洋島國斐濟和湯加貿易往來密切,而且血脈相連? ?當年湯加的王子們乘坐小木船一路向西,前往斐濟淘金,而斐濟女人也嫁給了這些湯加貴族。

If the superstructure is crossways , make sure that the foot section is not lying on the track groups or the outrigger struts of the auxilliary support ( if required , props up the boom to a higher level ) 如果上車為十字交叉型的,則務必確保臂桿根部沒有接觸到履帶組或輔助支承上的支腿壓桿(如夠必要,可把臂桿墊得更高些) 。

It is pointed out that wind vibration comfort control on tall steel structure by using modem control technique and the lateral deflection control on the frame - core wall structure by using outriggers can be realized 指出了現代控制技術對高層鋼結構風振舒適度控制及外伸臂對框架核心筒結構體系水平位移指標控制的實現。
