The moment - curvature relationship chosen is assumed to have a horizontal branch beyond yield, with the moment remaining constant at the ultimate value
所選用的彎矩曲率關系是假定超過屈服後有一個水平段，即彎矩保持在極限值不變。In the formula, our experience in structural strength design and the experimental results are considered. and such factors are also considered as differences in materials of the skin and the reinforcer, effects of bending, torsion, stretching and offcenter of the reinforcer. furthermore, through post - buckling stress analysis of the skin, it is shown that even low stress level will result in buckling of the skin, but the skin still has loading capacity
在總結過去結構強度設計和試驗分析的基礎上，應用扁殼理論，在廣義力與廣義應變關系中考慮了蒙皮與加筋不同材料以及加筋的彎曲、扭轉、伸縮和偏心等的影響，推導出適合於工程應用的加筋殼結構軸壓屈曲臨界載荷的計算方法;並通過對薄壁結構蒙皮后屈曲應力分析，說明蒙皮在很低的應力水平時就出現失穩現象，但失穩后的蒙皮仍具有一定的承載能力。As for the face, it was a speaking likeness in expression but it did not do justice to her figure, which came in for a lot of notice usually and which did not come out to the best advantage in that getup she could without difficulty, he said, have posed for the ensemble, not to dwell on certain opulent curves of the.
至於容貌，照片上倒是把表情照得栩栩如生，只是身姿方面卻委屈了她。平素她是極為引人注目的，但是這樣一裝扮，她的身段就沒有充分顯示出來。他說，那一次她要是拍幅全身照，就更上相了，豐滿的曲線230自不在話下。The research indicate that the structured soft clay has below several characteristic, the viscous strain is produced during the stage of primary consolidation and of second consolidation, and in the prophase, the relation of stress - strain - strain rate is unique, so the form of constitutive model, such as, f ( v ', e ) = 0, f ( ' v, e, t ) = 0, ca n ' t describe strain behavior of soil skeleton rationally ; the time - dependent properties involve three aspects, in addition the time - dependent strain, apparent preconsolidation pressures that depend on strain rate, and the effect of creep compression on apparent preconsolidation pressures ; because of holding structural strength, the mechanics characteristic is determined by the magnitude of stress, and the compression curve is composed of several sections. by combining structural yield stress and it ' s characteristics with the improved time line model, a new one - dimensional elastic visco - plastic consolidation model is established
研究結果表明，結構性土的固結過程具有以下特性：主固結和次固結階段都包含有因土骨架的粘滯性移動而產生的變形，而且在正常固結階段，存在應力?應變?應變速率的唯一性， f （ _ v ， e ） = 0 、 f （ _ v ， e ， t ） = 0形式的本構關系不足以描述土骨架的變形行為；固結壓縮過程中的時間效應包括三個方面的內容，除了應力應變關系與時間相關外，還包括粘滯性變形引起表觀前期固結壓力增加和屈服應力的應變速率效應；軟土的結構性使其力學特性與應力水平相關，壓縮曲線具有分段性。It is pointed that the thick unconsolidated layers above roof have effect on post - buckling behaviors of key stratum, the equilibrium path of roof is unstable from breaking to final subsidence
研究發現，頂板上覆厚鬆散沙層對關鍵層的后屈曲性態有影響；頂板從破斷至極限下沉其平衡路徑不穩定。This paper introduced the composition and classification of suspendome, generalized the nonlinear finite element computing methods. analysis to suspend - dome and single layer reticulate is conducted separately to the five type suspendomes which have same span but different rise - span, including force, displacement, eigenvalue buckling, nonlinear buckling, load - displacemnt tracking and nonlinear ultimate carrying capacity, every performance of suspendome was expatiated in the paper
通過對同一跨度、不同矢跨比的5種弦支穹頂結構和單層網殼進行的靜內力、節點位移、結構體系應變能、特徵值屈曲、非線性屈曲、非線性極限承載力、荷載-位移平衡路徑跟蹤分析和比較，闡述了弦支穹頂結構的各項性能，通過與單層網殼的比較，闡明了弦支穹頂結構的優越性。( 3 ) using yielding line theory, we educed ultimate capacity of slab - column connection which was bend destroy under vertical load, vertical load and unbalanced bend in the text
（ 3 ）利用屈服線理論，推導出豎向荷載作用下、豎向荷載和不平衡彎矩共同作用下板柱節點發生彎曲破壞時的極限承載力。Hold the load close to your body. keep your back straight and tighten your abdominal muscle to support the spine. stand with feet apart at shoulders width and avoid excessive knee bending so as to keep your balance
當提取地上的重物時，要屈膝蹲低及收起腹部，保持腰背挺直，好讓脊柱得到足夠承托，同時雙膝要微微分開如肩膊寬闊，亦不要過份屈曲，以保持平衡避免跌倒。分享友人
