Abstract


The composite frame is made ??of steel - concrete composite beams and steel columns , is a new structural system . With the continuous development and improvement of the structure design theory and material properties , high-rise buildings to a higher , span greater direction of development , stability issues will become more prominent . Composite beam steel frame is the overall stability of better than pure steel beam steel frame , but very few experimental and theoretical research at home and abroad on the combination of frame stability , a stable framework design theory used in the design of the composite frame , does not considering slip effect of the concrete floor with steel beams , resulting in uneconomical . This paper studies the steel - concrete composite beam steel frame stability . Consider a role in the performance of the slabs and steel beams slip elastic element stiffness matrix of the composite beam is derived . And on this basis to establish the format of the composite beam steel frame stability analysis calculations -QR method . Finally the C language to the preparation of the corresponding calculation program , using ANSYS finite element software to analyze the nonlinear stability of the composite beam steel frame in the fifth chapter . Draw some valuable conclusions by a numerical example , provides a new calculation method for similar studies and design optimization framework system , as well as the perfect combination of structure related specifications and procedures provide a useful reference .
