Many factors are considered in the study of the nonlinear buckling bearing capacities of the representative concrete filled circular and square steel tube columns, these factors include the sectional form, the slenderness ratio, the steel ratio, and the eccentricity ratio. the comparison between the test and calculating results shows that they have a good agreement. in theoretical investigation of the time - dependent behaviour of cft specimens, based on the three - dimensional viscoelastic theory, this paper proposed the three - dimensional finite element model of creep of core concrete, in which a linear three parameters visoelastic model was adopted
在對鋼管混凝土構件極限承載力的分析計算中，本文提出了核心混凝土的三維非線性應力?應變全量和增量本構關系模型，採用完全的拉格朗日表述來考慮與變形歷史有關的大變形問題，並對長細比、含鋼率和偏心率在較大范圍內變化的方、圓鋼管混凝土構件的非線性屈曲承載力分別進行了試驗和理論對比分析研究，結果表明二者符合較好。 -
With prestressed rolling mill of the middle steelworks of taiyuan iron and steel limited group company as the researched object, this article analyze the existent questions and research the initial stress of prestressed rolling mill and computer control system, analyze the design thought of prestressed rolling mill and clarify the relationship between the dimensional precision of rolled material and the rigidity of base of rolling mill and the main method to increase the rigidity of base of rolling mill, analyze how to confirm the rigidity, sectional area of handle and post, and pretightening force, put forward the viewpoint that the key to assure great rigidity is to assure that the remnant initial stress is always positive during rolling, and develop intelligent control system with plc as the core on the basis of the former research to assure that the remnant initial stress is always positive during rolling
本文以太鋼集團公司中型型鋼廠預應力軋機為對象，分析了該廠預應力軋機所存在的問題，對預應力軋機的預應力以及微機控制進行了系統研究；分析了預應力軋機的設計思路，闡明了軋材尺寸精度與軋機機座剛度的關系及提高軋機機座剛度的主要途徑；分析了預應力軋機設計過程中預應力軋機的剛度、預緊拉桿和機架立柱斷面積及預緊力的確定；提出了預應力軋機保證高剛度的關鍵就是「確保軋制過程中，殘余預應力始終大於零」的觀點；在前述研究的基礎上開發了以可編程邏輯控制器為核心的智能監控系統，以確保「軋制過程中，殘余預應力始終大於零」這個要求。
