合格梁-
Then an thorough computer modeling using finite element program with material, geometry and state triple - nonlinear taken into account is carried out on a series of influencing factors, such as comparison with npn - beam splice connection, comparison of varies designed theories, and the varying of fraction coefficient, diameter, grade, pretension and arrangement of bolts, thickness of web and flanges of beam and column, splicing location, axial loading on column, etc. lots of useful conclusions are drawn form computer modelling. finally, design and construction suggestions are given out. this study fills the black in the field of steel beam - to - column connection with cantilever beam high - strength bolted - splicing at both home and abroad
然後，本文在考慮材料、幾何和狀態三重非線性的基礎上，對該連接形式進行了全面的計算機模擬，主要考慮了帶懸臂梁段全螺栓拼接的樑柱連接節點與無拼接的樑柱連接及翼緣對接焊接腹板拼接的連接節點的對比，各種設計方法之間的對比，以及翼緣拼接和腹板拼接的螺栓間距、直徑和數量，拼接點與梁端之間的距離，梁和柱的翼緣、腹板厚度，柱的軸力，接觸面的摩擦系數，翼緣和腹板拼接板的厚度等因素的影響。 -
Based on the previous research results, the test study on quasi - static seismic resistance behavior of the monolayer and single - stride prestressed concrete flat - beam frame structures are mostly carried through. the low - cyclic reversed loading test of two frames with the same size and the same intension grade are conducted. one frame is made of ordinary concrete, the other is made of steel - fiber concrete
研究結果表明：將鋼纖維摻入混凝土中用於框架結構，能使預應力扁梁框架具有足夠好的抗震性能，只要設計得當，可以形成梁鉸耗能機構及整體破壞機制，且具有較好的耗能及抵抗強震的能力。 -
In recent years, developing completely along with high grade highway and stereoscopic transportation in cities, bridge development has entered the unprecedented high tide period. among them the box girder occupies important position in developments of the long - span pc beam bridge with its good section - form
公路及城市立體交通的全面發展，橋梁建設進入了前所未有的高潮時期，其中箱型梁以其優良的截面形式在大跨度pc梁橋建設中佔有極重要的地位。 -
So, the method, that is, determining adjusting coefficient of moment capacity of column - to - beam according to actual reinforcement of beam, which have been adopted by framework of gradel intensity - category 8 and of grade 1 intensity - category 9 can effectively form advantageous energy - dissipation mechanism under intermediate earthquake and rare earthquake
因此， 9度一級和8度一級框架按梁端實配鋼筋確定樑柱抗彎承載力級差系數的方法能較為有效的引導框架在中震及大震下形成有利的耗能機構。 -
The main task of the thesis is to judge availability of corresponding seismic measures after code revise through processing inelastic dynamic analysis with the method of multi - waves import for these framework of grade 1 and 2 intensity - category 8 and of grade 1 intensity - category 9 designed in terms of the revised criterions of gb 50011 - 2001 and gb 50010 - 2002. the results show that over - reinforcement of beam because of detailing is the most important reason disturbing framework from forming effective energy - dissipation mechanism
本文的主要任務是嚴格按修訂后的規范gb50011 - 2001和gb50010 - 2002設計8度一級、二級框架和9度一級框架，通過多波輸入（每個結構輸入5條天然波和一條人工波）對所設計框架做非線性動力反應分析，然後按結構的反應結果檢驗抗震設計措施加強后的結構抗震性能，由此對修訂后規范相應措施的有效性做出一定的評判。 -
It is sand blown by the wind excessive district, roof beam hills area, low mountain incomplete district, etc. forefathers study on loess plateau concentrate on land type divides, the land resource is classified and grade mainly, small basin manage, soil corrode, land person who suitable for appraisal, land utilize the respects, such as assigning area, etc. but static, analysis and research that determine the nature mostly, utilize dynamic change course research and corresponding driving force system study to land very few
但多是靜態的、定性的分析研究，而對土地利用動態變化過程研究以及相應驅動力系統研究甚少；對區內不同地貌、行政單元區域的土地利用動態變化的區域差異研究較少，而且區內差異研究較粗略，多依自然因素劃分單元、進行定性的闡述，不能客觀而定量的反映驅動因素中各因子的作用力大小。
