Research On Numerical Simulation Analysis Of The Whole Process Of Steel Reinforced Concrete Torsion Members

Steel Reinforced Concrete structure has a good seismic performance andreasonable mechanical properties. Compared with reinforced concrete,Its bearingcapacity is greatly improved. So in the recent years, Steel Reinforced Concrete structurehas been used more and more widely.The paper uses ABAQUS software for numerical simulation of the component.The paper first simulates a specimen component of literatures. Comparing these resultswith the experimental data, It was found that the simulation value and the actual value isidentical. And the results can more accurately reflect the mechanical properties of themembers subjected to torsion. So It identifys the finite element model is effective. Theresult also determines the unit type selection, the method of element meshing principleas well as finite element simulation of the constitutive relation of concrete and steel.But the interaction between steel and concrete is very complex, so the currentcalculation method of ultimate torque of Steel Reinforced Concrete is superpositionmethod. Based on the studying of stress mechanism of pure torsion members, the paperproposes another superposition method, namely the Combination, and proves itsaccuracy by means of the finite element results.Through the finite element analysis not only obtains stress relationship curve butalso gets the concrete, reinforced, steel stress nephogram and cracking torque andultimate torque. Through these data, verifying the combination method.The resultsshows that this method is more suitable for steel which located the effective thickness ofprotection layer. According to the finite element values, analyzing the influence factorsof the cracking torque and ultimate torque of each component and studying themechanism of influence of these factors.
