| Summary: | Reinforced concrete structure is vital in construction industry and the demand from the users is strictly high and rises each day. Although the usage of concrete structures is being improved day to day, there is always a chance to improve the structure. The limitation of plastic knowledge on concrete beam behaviour has become the reason why there is still disaster that occurred everywhere. Moreover, with the existence of computing software that is capable to complete an analysis in a short time, the usage can be still questionable whether the product is reliable or not. LUSAS was chosen in this study to determine the plastic behaviour of concrete beam model and all the results were compared to experimental data for verification. The concrete beam materials is modelled by concrete (model 94) and reinforcement is modelled by Von Mises Yield Criterion. Based on the analysis, there is a slight difference between LUSAS and experimental data where at the first crack load of the sample, experimental data recorded a deflection of 2.96 mm while LUSAS stated 3.06 mm.The sample failed in flexural with concrete crushing and the results were verified using the stress contour |
