S S imulation and Imitation on the Damage of RC Bending Members Cross—section Abstract：People had 10ng designed and analyzed the RC structures by the empirical f．onnula． In the past 40 years，晰m the rapid deVelopment and extensive use of the computers，many calculations that are foHnerly dimcult to work out may be s01ved by computers．With the growing perfection of me computer graphics techniques，People not only can get the expected computations， but alsO can simulate a11d imitate the whole process of structure stress． Furthermore，me simulation results are basically in line with the exDerimental results．In contrast：(1)Simulation aIld imitation，just 1ike me way of experimem by the computer，are convenient as weU as quick．In addition，simulation and imitation do not depend on lots of raw materials to make models or la唱e numbers of experimental instmments and apparatus．(2) Because of the difference between the experimental model a11d real stmcture，sometimes，the experimental result can’t be used directly to guide the real proi ect．But simulation and imitation only need to be imputed a variety of parameters in order to do experimem in 1ine with the real structure size．(3)Sometimes people only obtain seVeral discrete data with limited quantity 矗om experimems．On contraSt，simulation a11d imitation can help people get many kinds of data which can directly show the ea’ect of the whole structure under the stress．f4)The above characteristics can also giVe如U play to good economic and social benefits in the process of teaching．The research contents of the p印er are as folIow：‘ 1．Analyses t11e d锄age condition of RC simple beam cross．section as wen as the features of dia’erent stress phaLses．The p印er mainly studies the cross section d锄age of the appropriate reinforcement be锄in RC simple be锄． 2．Studies the constitutive relations that RC simple beam cross—section abides bV under difrerent stress phases。This paper concludes and analyses the constitutive relations that the RC si
