  1. In the second place, based on the asu of buggenum igcc plant in netherlands, both static and dynamical model for distillation tower of the asu are created and some valuable conclusions are gained as well. finally, a compartmental simplified model is created for distillation tower of the asu, in order to reduce the simulation time and increase the simulation efficiency. the new model will be helpful to the further simulation and on - line optimal control for the asu of the igcc plant

    其次，本文以荷蘭buggenum電站的空分系統為原型，基於matlab建立了空分系統精餾塔的半圖形化動、靜態數學模型，並通過模擬，得出了一些有價值的結論：當空分系統的壓力變化時，氧氣產品濃度的響應時間常數為兩小時左右，說明空分系統是igcc電站最大延遲環節；而且雖然氧氣濃度最後會穩定在igcc電站所要求的范圍之內，但在過渡過程中會超出限制，這些都為igcc電站的安全運行及控制系統設計提供了有價值的信息。
  2. The truss arch structure is a three - dimensional higher statically indeterminate structure, and no definite expression of the performance function can be given for its unbelievable complexity

    桁架拱結構是一個高次超靜定的復雜三維結構，構件的功能函數沒有明確表達式。
  3. 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。
  4. It ' s the first time clearly and systematically to present the concepts of restraint influence coefficient of steel to strain increment, to curvature increment and to deflection increment due to creep which are different each other. theoretical formulae are established, and approximate formulae are also obtained while considering the characteristics of common - used concrete and ambient condition of real bridges in china. so, an approximate restraint influence coefficient method to analyze the effect due to creep and shrinkage in pc bridges is put forward, and the equations to estimate second - force due to creep considering influence of steel in system - transferred continuous pc bridges is also established

    本文首次清晰而系統地提出了鋼筋對徐變的不同效應（徐變應變、徐變曲率、徐變上拱）約束影響系數的概念，建立了相應的計算式；結合我國普遍採用的混凝土的徐變特性和橋梁的構造特點及工作中南大學博士學位論文摘要環境特徵，給出了具有較高計算精度的實用計算式;在此基礎上，建立了橋梁徐變效應近似分析的鋼筋約束影響系數法，並推導出了考慮鋼筋影響的超靜定梁徐變次內力的近似計算式，可方便地應用於橋梁研究和設計中。
