Numerical Simulation Analysis Of The Typical Reinforced-Concrete Joint Of Dispersive Tube Structure

Dispersive Tube Structure is a new type of structural system applying to high-risebuildings with excellent performance in structure and economic according topreliminary research. Based on the existing research results, the paper has primarilyresearched on numerical simulation analysis of wall-beam joints in complex stresssituation in dispersive tube structure.Firstly, using ANSYS as a platform and APDL as the foundation, the paper discussednumerical simulation analysis methods of reinforced concrete wall-beam joints indispersive tube structure, and expounded the numerical simulation and the numericalmodel construction and points for attention in numerical analysis in reinforcedconcrete structures, and analysed numerical simulation results.On this basis, taking practical engineering projects as background, employingstructure design software SATWE which is widely used in the industry to calculatethe structure, analyzing overall wall-beam-full board joints bearing complicatedforces in dispersive tube structure, in terms of structural deformation, crack ofconcrete, stress-strain condition of reinforced concrete, bond-slip state of concrete andfailure pattern of joints, the paper came to the following conclusions:(1) Dispersive tube structure is an excellent structure system applying to high-risebuilding, which has been preliminarily researched. Although it has broadapplication prospects, there are still many problems needing further study;(2) Numerical simulation analysis of local wall-beam joints bearing complex load indispersive tube structure could employ ANSYS to carry on the analysis. Fromestablishment of numerical model, simulation of steel and concrete, simulation of thebond-slip phenomenon to the nonlinear analysis, parameter selection, matters needingattention in calculation, etc, all these issues can be applied with methods of thispaper for further research, and cooperating with APDL to write finite elementanalysis program and enhancing analysis efficiency provide foundations for thesubsequent research;(3) The paper conducted a thorough finite element analysis on some commonwall-beam-full board joints bearing more complex loads with aforementionedmethods. It was found that some problems existing in the results at such jointscalculated by commonly-used structure design software need extra attention, thereforethe paper put forward some feasible solutions.
