The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly, the research creates and solves the ship large amplitude motion equations. on the one hand, the actual calculation takes into account the coupling between the different motion modes, on the other hand, in the process of calculation of the ship hydrodynamic coefficient, it considers the influence of the nonlinear factor. the hydrodynamic coefficient used in the calculation of froude - krylov force, diffraction force and radiation force changes instantaneously following the draft, and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull
本文的研究分為二個部分:首先利用frank源匯法計算水動力系數,計算包括不同吃水時的附加質量和阻尼系數,吃水范圍涵蓋了船舶大幅度運動時所有可能的吃水;然後建立和求解船舶大幅度運動方程,在實際計算時一方面考慮了運動模態之間的耦合,另一方面在計算水動力時,考慮了非線性因素的影響。 froude - krylov力、輻射力、繞射力中的水動力系數隨吃水瞬時變化,靜浮力的計算精確到船體瞬時濕表面積,最後用四階龍格?庫塔方法在時域內求解船舶運動方程,並進行了載荷計算。Then figure out the wind load in term of the load criterion and the wind tunnel test results separately. by comparing with the two results, we can draw a conclusion that the values which generated by the load criterion are bigger than these ones generated by the other. in order to calculate and design in the worst situation, the paper select the bigger basic wind stress and then turn the area - load into liner - load to receive the displacement of the nodes and the internal force of the cells generated by the static wind load
由此,得出用於作業棚結構設計的數據,進而按建築荷載規范和風洞試驗數據分別計算出風荷載標準值以及基本風壓,通過對兩種靜力風荷載計算的結果進行比較,可以看出,按規范計算風荷載的結果在結構的整體計算中偏於保守。按照最不利情況計算的設計準則,本論文選用較大的基本風壓值按受力面積分配的方法把面荷載轉化為線荷載代入midas運算程序中,求得該結構在該靜力風荷載作用下的節點最值位移。Under the horizontal earthquake action and wind force, aim at " the pure frame structure with rectangle columns ", " the pure frame structure with special - shaped columns ", " the frame - truss structure with special - shaped columns " and " frame - shear wall structure with special - shaped columns ", earthquake action analysis was done by the spacial finite element method through the changes structural parameter. analyzing systematically " structure vibration mode ", " vibration period ", " structure lateral rigidity ", " seismic action force ", " seismic response force ", " floor seismic shear force ", " lateral horizontal displacement of structure " and " members internal force ". results indicate : ( 1 ) based on equal area, the special - shaped columns replaced the rectangle columns, the structural lateral rigidity enlarges, the lateral displacement minishes obviously, the earthquake response increase slightly, the biggest increasing amount of frame columns axis - compress ratio is smaller than 0. 08. the whole aseismic performance of structure has improved ; ( 2 ) when the section ' s length and section ' s thickness ratio of special - shaped columns is smaller than 3. 6, the structure benefits to resist seismic action ; ( 3 ) the angle of horizontal seismic action with the whole coordinate is 0 degree, structure earthquake response is bigger, belonging to a control factor of structure aseismic design ; ( 4 ) the frame - truss structure with special - shaped columns and the " a " - brace has the biggest lateral rigidity ; ( 5 ) the frame - shear wall structure with special - shaped columns have bigger lateral rigidity and smaller displacement, members internal force enlarged just rightly, have much superiority of resisting seismic action ; ( 6 ) in the higher seismic fortification criterion region ( 8 degree of seismic fortification intensity ), aseismic disadvantageous building site ( iii type site ), adopting special - shaped columns structure system, should reduce possibly the building ' s self - weight in order to reduce the earthquake response ; ( 7 ) the response spectrum method of computing seismic response and the time - history analysis method have similar analysis result
西安理工大學碩士學位論文在水平地震作用下,並考慮風荷載組合,分別對「矩形柱純框架結構」 、 「異型柱純框架結構」 、 「異型柱框一析架結構」及「異型柱框-剪結構」等四種結構體系,通過改變結構參數,運用空間有限元方法,進行地震作用計算。系統地分析研究「結構振型」 、 「振動周期」 、 「結構側向剛度」 、 「結構地震反應力」 、 「樓層地震剪力」 、 「結構側向位移」 、 「層間位移角」 ,以及「構件內力」 。結果表明:在等面積原則下,異型柱代換矩形柱后,結構剛度增大,側向位移明顯減小,地震反應力略有增加,框架柱軸壓比最大增幅小於8 % ,結構整體抗震性能有所提高;當異型柱肢長肢厚比小於等於3 . 6時,結構有利於抗震;水平地震作用力與整體坐標夾角為0度時,結構地震作用效應較大,屬結構設計的控制因素之一;異型柱框一析架結構採用「人」字斜撐,側向剛度大於「八」字斜撐和「人一八」字混合斜撐;異型柱框一剪結構側向剛度大、位移小,構件內力增大適中,是一種抗震性能優越的結構體系:在抗震設防烈度較高地區( 8度)和抗震不利的建築場地( m類場地) ,採用異型柱結構體系時,應盡可能減輕結構自重,降低地震作用力;分別採用「振型分解反應譜」法和「時程分析」法進行地震作用計算,兩種方法所得結果基本一致。The bearing capacity of a soil means the maximum load per unit area ( usually in terms of kn / m2 ) which the ground will safely support
