Using Finite Element Analysis To Study Frame Beam Supported Both In Beam And Column

For the reinforced concrete frame structure, it is a normal method of structuraldesigners lacks a certain pillars in order to receive a larger architectural space. While theoriginal frame beams was two-side propped up on the pillar has turned out to be one sidesupport on the pillars but the other on the beams. As we know, not each people does allclear understand to this kind of ultra convention structural. In China, study on thisparticular beam theoretical and experimental is being inadequate, and so it is necessary toconduct an in-depth research.This definition: one end of the support on the other side of the beam support beam inthe column for the secondary beam, supporting the sub-beam beam beam beam bearingthe main beam. Using ANSYS finite element software to establish a layer of1×2framestructure that contains the other end of the beam supported at one end to support the beamline in the column. Finite element model used in Link8and SOLID65unit change in steelstress were simulated and the launching of concrete cracks, the use of quasi-staticdisplacement of the loading mode to simulate the seismic effect. Analysis of the beam inthe reinforced stress distribution, as well as connecting with the floor in the steel stressdistribution. The results show that: For the special primary and secondary beamcontaining the structural system in the quasi-static lateral effect, when the applied loadfor the displacement of40mm, the secondary girder support steel bar first occurs in theking post steel bar submits and this secondary girder is smaller than far in beam-beamrestraint the beam-column end.In addition, through the establishment of seven overall model, which includingdifferent floor thicknesses, different main beam and beam cross-section of different times.Analysis of the plate stiffness, the main beam stiffness and the stiffness of the beam sub-beam effects. Concludes: in the beam design should take full account of the relativestiffness of the floor and the factors that primary and secondary beam.
