Steel frame with welding joint easily occur brittle collapse because of having a low ductility at joints then , a semi - rigid connected steel frame has large the energy absorption capacity which can resist dynamic loads and the using steel qualities of bracing system and joints are small so adopting a semi - rigid jointed steel frame is economical and stable but for semi - rigid connections are complex and variable , in conventional analysis and design of steel structures , it is usually assumed that the connections between columns and beams are either rigid or pinned the analysis of steel frames adopting the assumption can simplify the procedure of analysis and design , but cannot precisely reflect structural practical circumstance and the errors of calculating results are large , even , get incorrect conclusions semi - rigid connection was referred to in chinese code for design of steel structures ( 2001 , 10 ) , however , it isn ’ t specified how to apply semi - rigid joints in design in fact it cannot be carry out the purpose of the paper give a calculating method that accords practical engineering and easily put into effect worthwhile it is going to promote the development of semi - rigid jointed steel frame in design and heighten structural stability in the paper , at first some commonly employed methods for the modeling of connection behavior are introduced richard abbott function modeling of connection is adopted for extended end plate bolted connection by the 34 test data comparing to regression analysis indicate richard - abbott function modeling of connection represents an excellent fit to test data then after a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring , base on rotation and displacement equation derive the element stiffness matrixes with semi - rigid connections where the effects ofj ointed flexibility geometric non - linearity and shear forces in the connection deformations have been considered in and fixed - end forces are modified finally, a program for calculating semi - rigid with incremental - iterative method has been

    本文的目的就是為半剛性連接鋼框架的設計提供一種既符合工程實際又簡便易行的計算方法,供規范使用過程的補充、延伸或參考;同時,也將促進半剛性連接鋼框架設計技術的發展,為提高結構安全性能、節省工程成本發揮應有的作用。本文首先介紹了常見的幾種應用較為廣泛的樑柱連接彎矩轉角關系模型,在分析比較的基礎上,選用richard ? abbott函數模型作為外伸端板連接彎矩轉角關系模型,通過對34個外伸端板連接的實驗數據與回歸分析得到的參數比較可知,經回歸分析得到的此模型參數與實驗數據符合較好。然後用彈簧表徵連接點的轉動剛度,根據梁的轉角位移方程推導出半剛性連接的剛度矩陣,在單元剛度矩陣中考慮了節點柔性、幾何非線性和剪切變形的影響,並對固端力進行了修正,最後用增量迭代法編制有限元程序進行計算和分析。
  6. C ompared the results of structural period, displacement and internal forces of mode 1 with mode 3, we can know that the hypo - frame can increase the lateral stiffness of the mega steel - frame structures, decrease lateral - deformation of the structures, especially decrease the maximum inter - storey displacement obviously, and get the internal forces and deformation of the whole structure more uniform. from the analysis results, it can be found that the maximum axial force gets less with hypo - frame than without it, and the maximum shear force and bending moment get more with hypo - frame than without it. thus it can be seen that the mainframe can be an independent structure system by itself, but the cooperation of main and hypo frame should be considered for conducting the entire analysis and design, otherwise the mega structure can be unsafe, in addition, from the comparing analysis, it can be found that the shear force and bending moment of inside - row columns are increased much more than those of outside - row ones in a mega column

    通過3個算例方案1和方案3結構周期、位移和內力反應的比較分析可知,次框架可以進一步增加巨型鋼框架結構的抗側剛度,減少結構側向變形,特別是明顯減少了結構最大層間位移,使整個結構的內力與變形分佈更為均勻;次框架的加入使主框架柱最大軸力較無次框架情況減少,而主框架柱的最大剪力和彎矩較無次框架情況都有所增加,由此可知,雖然主框架本身可以成為獨立的結構體系,但在分析設計時,還應該考慮主、次框架協同工作,進行整體分析、整體設計,否則結構會偏於不安全。
