Simulation And Imitation On The Damage Of RC Bending Members Cross-section

People had long designed and analyzed the RC structures by the empirical formula. In the past 40 years, with the rapid development and extensive use of the computers, many calculations that are formerly difficult to work out may be solved by computers. With the growing perfection of the computer graphics techniques, People not only can get the expected computations, but also can simulate and imitate the whole process of structure stress. Furthermore, the simulation results are basically in line with the experimental results. In contrast: (1) Simulation and imitation, just like the way of experiment by the computer, are convenient as well as quick. In addition, simulation and imitation do not depend on lots of raw materials to make models or large numbers of experimental instruments and apparatus. (2) Because of the difference between the experimental model and real structure, sometimes, the experimental result can't be used directly to guide the real project. But simulation and imitation only need to be imputed a variety of parameters in order to do experiment in line with the real structure size. (3) Sometimes people only obtain several discrete data with limited quantity from experiments. On contrast, simulation and imitation can help people get many kinds of data which can directly show the effect of the whole structure under the stress. (4)The above characteristics can also give full play to good economic and social benefits in the process of teaching. The research contents of the paper are as follow:1 .Analyses the damage condition of RC simple beam cross-section as well as the features of different stress phases. The paper mainly studies the cross section damage of the appropriate reinforcement beam in RC simple beam.2.Studies the constitutive relations that RC simple beam cross-section abides by under different stress phases. This paper concludes and analyses the constitutive relations that the RC simple beam is involved in elasticity phase, plasticity phase and the damage phase.3.Utilizes the ANSYS software as the platform and uses its powerful functions to set up the real model of RC simple beam stress. Then divides it into nets in order to automate the calculation analysis process and make the analysis results visible as well as make the dynamic imitation.4.Contrasts and analyses the experimental results and the simulation results in order to further improve the simulation analysis process and provide beneficial suggestions for future teaching, research and production practice.
