Under the guiding principle to be innovative and practical at the same time, hhd ' s approach seeks to provide proper design response in relation to time and place, with emphasis on respect for the urban context, the natural environment, and the market and economic forces
遵循創新和務實的原則，充分尊重城市文脈、地理環境和經濟技術條件，保持平實的創作心態，做因時、因地、得體的設計。 -
3. according to the principle of the finite element method, the research establishes finite element models of the vibration transportation mechanisms, some model parameters such as the frequency and vibration type are confirmed and validated by the modal analysis, then which analyzes dynamic - state response of the model and confirms the swing distributing of the models, thereby make the design of models precise. 4
根據有限元法的理論，建立振動機構的有限元力學模型，對該力學模型進行模態分析，通過模態分析確定拋秧機振動形態和所需的頻率等參數；然後此基礎上再進行力學模型的穩態響應分析，研究該模態下機構的振幅分佈，以確定模型設計的準確性。 -
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。 -
In this paper, the three level fortification criterion, two stage design method and the elastic response spectrum theory are adopted, and the program of nba ( the program of nonlinear - aseismic analysis for beam bridge ) is used to calculate. through gathering, analyzing and calculating a lot of bridge design materials, this paper induces a simple way to calculate the relative displacement of the beam and the pier, and then according to the current design method, it concludes a better design principle of the supporting length of the beams. at the same time the dynamics is adopted to put forward the design method of the carrying capacity and the lengthen of prestress wire ( steel bar ) falling - off prevention structures of highway bridges
