The research object in this text is the actual project - - the mansion of yatingyuan ( 40 layers above the ground, 125. 4 meter high ). the structure - design is by satwe and the analysis of the structure dynamic characteristic and earthquake response by sap2000, whose calculation models are set up according to the actual size of the structure. in satwe, the analysis model of beam and column is simulated by frame - element, slab is plane - element, shear - wall is wall - element and slab is infinitely rigid in the internal and zero in the external ; in sap2000, beam and column is frame - element, slab and shear - wall is shell - element and slab is elastic floor
本文以實際工程項目? ?雅庭園商業中心大廈（地面以上40層，建築總高度為125 . 4米）為研究對象，結構設計採用satwe ，結構的動力特性和地震反應分析採用sap2000 。結構satwe和sap2000分析的計算模型均按結構的實際尺寸建立， satwe分析模型的樑柱採用桿元模擬，樓板用薄壁殼元模擬和剪力墻用墻元模擬，樓板平面內無限剛、平面外剛度為零； sap2000分析模型的樑柱採用桿元模擬，樓板和剪力墻用殼元模擬，樓板為彈性板。Specifically, according to the w - w five parameters failure theory, the fracture criterion of crack is established, and the state of crack ( open or close ) is judged by the values of the crack strain. combining the two points, the predict - model about the failure of concrete material is established. this predict - model can predict 16 failure forms, and basing the different failure form predicted after crack, the stress - strain relationship matrix of concrete material is adjusted
具體來講，根據w - w的五參數混凝土破壞理論，建立混凝土的開裂準則，根據開裂應變值來判斷裂縫是張開還是閉合，從而在兩者基礎上建立了裂縫的開裂預測模式，總共有16種開裂模式；裂后根據具體的開裂模式及殘余抗剪能力來調整混凝土的本構關系矩陣，即用等效剛度代替原有剛度，考慮到垂直於裂縫方向的剛度為零，這樣會使裂后的總剛出現病態，為此文中通過引用鬆弛系數來對出現裂縫的單元進行預處理，一方面可解決因過大的舍入誤差導致計算結果的不可信問題，另一方面就是可加速收斂。If the inputted accelerations are velocity - zeroized and the damage value is calculated according to shear stress " extrema, as to 100 - meter - high earth dam, multi - point effect is not distinct ; but as to 240 - meter - high earth dam, in the part where permanent displacement and damage value is originally bigger the response is less tenser than that by one - point input, and in the part near basement the maximal shear stress and damage value is bigger, that is the multi - point effect in time domain
若同時進行了多點地震動速度歸零化和採用基於極值的損傷值計算方法，對於100米高的土石壩，多點輸入與單點輸入反應十分接近。對於240米高的超大型土石壩，壩體內永久位移和損傷值較大的部位多點輸入的反應量較小，這是多點輸入反應的特點或說多點效應。另外，多點效應也包括壩基部位的最大動剪應力和損傷值偏大這一效應。A more reasonable method to calculate soil ' s damage value is advanced, which bases on extrema of irregular dynamic shear stress. previously it bases on peaks of shear stress to calculate damage value, but by this method the destructive action of multi - point inputted earthquake is overestimated, especially in the second half section of responding shear stress " time history the shear stress caused mainly by differential force undulate slightly on one side of its zero line
以往計算土體在不規則的動剪應力作用下的損傷值根據的是動剪應力的峰值，在時域內多點輸入分析中，由於差動力的的存在，使得時程後段動剪應力不穿零而在一側做幅度不大的波動，基於峰值的損傷值計算特別過高地估計了這段剪應力的破壞作用，過高的程度還隨延時增加而增加。The demarcation point of, which is the parameter in erf ' s yield stress equation, is 2. 0. for, the dynamic characteristics of the clutch are remarkably different from those for. thirdly, the linear stability of plane shearing flow with non zero pressure gradient is studied
論文第三部分對電流變液非零壓力梯度平板剪切流動的穩定性進行了分析，提出流場對屈服應力達到飽和的概念；並得出平板壁面剪切運動以及電流變液屈服應力的提高，都將使流動穩定性增強的結論。When the substrate is alios ceramic substrate, the shear stress hovers over a relatively high negative level during curing process and steps to a relatively low level during cooling down
對于陶瓷基板，在固化過程中，剪切應力並不象fr4基板上所表現的那樣，在零點上下波動，而是處於一個絕對值較大的負值。3. based on the assumption of general slip surface, a general formula of safety factor of slope is presented in which the forces exerted on the slices exactly satisfy the equilibrium condition. using the method the chapters introduced to search critical slip surface, and proved by examples, this method is more reliable, and can search, simulate the critical slip curve
推導出了滑動面為任意現狀，邊坡體內作用有各種荷載且滿足力平衡條件下的邊坡穩定系數計算公式（在進行條分計算時，假定條間僅有水平方向作用力，豎向條間剪力為零） ，利用本文提出的遺傳進化搜索方法搜索邊坡最危險滑動面。The rapid and reversible change between fluid and solid enables erf potential applications in mechatronic devices, cars and general machines. the transmission ability of a self - made cylinder coupling with zeolite - based erf was investigated, the torque transmission of the coupling in wide ranges of driving speed and electric field was measured. the relationship between the transmission torque, the zero field viscosity of erf and shear yield stress of erf under different electric fields was obtained and compared with theoretical prediction
本文用沸石和硅油配製的電流變液，在自製圓筒式聯軸器上研究了在一定的速度范圍和有無電場作用條件下測量了其扭矩傳遞能力，獲得了傳遞扭矩與零電場電流變液粘度以及電場中電流變液的剪切屈服應力之間的關系，並與理論值進行了比較。Moreover, experimental results have proved that the method is robust enough to some image degradation process such as cropping, jpeg compression and sharpening etc. embedded zerotree wavelet coding ( ezw ) algorithm, it is found that this algorithm does not make full use of the properties of human visual system ( hvs ) to eliminate visual redundancy
實驗證明，該方法對剪裁、 jpeg壓縮和銳化等圖象退化處理均具有一定的抵抗力，是一種行之有效的水印嵌入方法。本文在對零樹編碼方法研究的基礎上，針對零樹編碼方法沒有充分利用hvs特性來有效消除視覺冗餘的缺點，提出了一種基於小波系數的零樹編碼方案。分享友人
