Research On The Bearing Capacity Of Web Side Plate Frame Composite Beams

Web side plate frame beam, which is similiar to the traditional concrete-steel composite beam members.changing connection and shift down certain height into the concrete flange,received also by the level change non-flush, side girder that is down, steel beams with concrete flange and through overall shear connectors, the formation of new connections in composite beams. Web side plate beam, simplied as side plate composite beams. Though it is a new connection style, but it still possesses the advantages of traditional composite beam. This beam can be used for high-rise buildings, bridges structures, as well as industrial plant expansion reconstruction. While the greater advantage of web side plate composite beams is it can reduce the overall height of the composite beam cross-section effectively, with the application of this beam, the free height of each floor will increase a lot, and great economic benefits will surely obtain. The shifting of concrete flange portion of the height is equivalent to provide lateral support for main girder, increases the stability of the composite beam structure layout sides, and gets the flexural capacity improved.At present, there is few research on side layout composite beams, similar new connections are mainly certain steel beam flange connection design patents, the range of applications is limited, while composite beams side layout is popular with a wide application, and has good prospects for development. Meantime, this beam is a kind of inheritance and development for traditional concrete-steel composite beams. Therefore, in this paper, the study on web side layout frame composite beams has an important meaning.Based on the finite element software ABAQUS side plate composite beam bearing capacity, need to the composite beam test ABAQUS finite element analysis is accurate and effective, and using the finite element software modeling of side plate composite beam bearing capacity and its influencing factors. The research work of this paper is as follows:For full size finite element simulation of 3 composite beams on the existing test, the calculated results and experimental results verify that the main purpose is to verify the finite element software in the right combination beam analysis, provide the basis for the analysis of the next chapter shows the side plate bearing capacity of composite beams.In this paper, using nonlinear finite element method, analysis of the 14 web side plate of composite beams under monotonic loads performance. In the loading process, two groups of web side plate composite beam is caused by bending failure, by finite element analysis, bearing capacity, deformation, side plate composite beam by slip, concrete strength, thickness analysis. Effect of stud spacing.
