Match Twin Screw Asymmetric Steel Reinforced Concrete Beam And Node Of The Nonlinear Finite Element Analysis

The beam-column node is the connection of the key parts of the beam and column in the transfer story structure. Since nowadays the demand of architectural function of the modern tall buildings to buildings, at the bottom of tall building needs to use the large span space structure. So the tall building with box transfer beam steel reinforced concrete pillar between nodes reliable connection is particularly important. There are a lot of researches for steel reinforced concrete beam research at home and abroad. However, the asymmetric steel reinforced concrete beam and reinforced concrete frame pillar connecting node of this structure form is seldom studied.This dissertation establishes the solid model for the beam-column node nonlinear simulation analysis through the large software ANSYS. First of all, designed three steel encased concrete transfer beam structure components, including:symmetric steel reinforced concrete beam, single shaft asymmetric steel encased concrete beams and partial in tension of biaxial asymmetric steel encased concrete beams; Through the three structures of ANSYS nonlinear calculation results, the thorough analysis of steel reinforced concrete beam internal steel bone stress distribution and stress mechanism of found that using partial in tension of biaxial asymmetric steel encased concrete beams in mechanical performance is superior to the steel encased concrete beams is symmetrical, but in the limit loads, the steel bone bottom flange suffers more stress. Besides, this dissertation puts forward for some feasible methods asymmetric steel encased concrete transfer beam using asymmetric structure form.On the basis of the mentioned above, this dissertation also deduces the standard theory formula and puts forward the suggestions of the calculation method of the asymmetric steel encased concrete transfer beam by ANSYS. Finally, using the finite element software ANSYS partial in tension of asymmetric steel encased concrete beams with reinforced concrete frame pillar for edge nodes cyclic load simulation, and examined the axial compressive ratio, concrete strength grade, etc factors on the edge nodes and the influence of the bearing capacity of the joints is calculated.
