Study On Analysis Method Of The Cellular Steel Framework Structure

Cellular steel frame structure is a new steel frame structure which makes the cellular beam and solid web or cell column connected by welding or bolting. It not only has the technical advantages of the traditional steel frame structure and the lower structure weight due to the member web consecutive openings, Province, steel and other advantages. Pipeline going through the cellular holes, can reduce the building storey. Visible, applied it in high-rise buildings, can obtain better economic and social benefits.View of the above-mentioned advantages of the cellular component, The cellular steel frame structure is bound to be widely used with the continuous development of the urban construction. Currently maturing at home and abroad for ordinary steel frame,but cellular steel frame system is still blank, especially cellular steel frame structure analysis method, home and abroad has not been reported, more specific research. Therefore, the depth theoretical analysis and finite element simulation of cellular steel frame system, it is particularly necessaryIn this paper, on the basis of steel frame structure in the cellular quasi-static test, the finite element analysis was used to do simulation analysis. Study cellular beams, columns, under the influence of the holes (cutout shape, size and position), find out the stiffness in the elastic stage, compare the stiffness of the same cross-section corresponding with the cellular structure of a solid web structure, fitting the stiffness reduction factor in the elastic phase cellular. Making the analysis of cellular framework through reduction factor to simplify the analysis of the the ordinary solid web framework, research has tended to for castellated beams perfect, this paper studies the cellular column flexural stiffness reduction factor. On this basis, using refined plastic hinge method of ordinary framework through the reduction factor, achieve its application in a cellular framework, elastic-plastic analysis of the cellular structure of the overall, designers further the design of the structure to be more concise.In this paper, established cellular space framework model to study the elastic-plastic analysis of seismic waves, and the main cellular column shear performance, because the maximum stress at from the column foot holes, thereby establishing a single the Pin3c2k cellularframework model, in expanding high ratio and Pitch constant, longitudinal research hexagonal holes and round holes the honeycomb framework for cellular column the total number of openings, which provide for the the cellular framework seismic performance design.Finally, this paper summarizes the results of research, derived the elastic phase hexagonal holes and round holes cellular column equivalent stiffness reduction factor, and to study the cellular framework of elastoplastic stage, to identify the expanding high specific Pitch certain circumstances, hexagonal holes and roundthe shaped holes cellular column longitudinal the opening total number of suitable and proposes the main content of further study which cellular steel frame structure requires.
