Failure Behaviour

Software simulation enables design engineers to have a better picture of possible structural failure behaviour and determine the accuracy of a design before the actual structural component is fabricated. Finite element analysis is used to simulate the behaviour of the reinforced concrete beam under the flexural test. During the flexural test, results are recorded for both simulation and experimental tests. By comparing the results, beam displacement, crack patterns, and failure modes can be studied with better accuracy. The accuracy percentage for yield load and ultimate load between the two tests results were 94.12 % and 95.79 %, respectively, whereas the accuracy percentage for elastic gradient before the yielding stage was 81.08 %. The behaviour between simulation and laboratory models described is based on crack pattern and failure mode. The progression of von Mises (VM) stresses highlighted the critical areas of the reinforced concrete beam and correlation between the experimental specimen, in terms of flexural cracks, shear cracks, yielding of tension reinforcement, and the crushing of concrete due to compressive stress. This paper concludes that simulation can achieve a significant accuracy in terms of loads and failure behaviour compared to the experimental model.

Material Response

Glass fibre composite reinforcement bars have been used in the reinforced concrete structures as a powerful solution of the steel corrosion problem. This research work aims to use a 3D finite element method and EURO – code models to simulate a concrete beam reinforced with fibre composite bars under the effects of high temperature. The behaviour of the structure is very complex due to load combination and different material response. The applied load was an external mechanical load and a thermal load. The material response was considered as thermal expansion, cracking, crushing, yielding and changing of material properties with the temperature increase. The FE element was modified to allow temperature distribution and material properties changing to throw thickness of the concrete beam. In addition, the geometrical non – linearity is considered in the analysis due to the large deflection of the structure. The prediction results were compared with the available experimental results, and it gives a well correspond.

Reinforced concrete is one of the most widely used building materials in Indonesia due to its workability, easiness, and reasonable price. Meanwhile, it is very important to understand the response of these elements during the loading process to ensure the development of an effective structure and one of the most effective numerical methods for reinforced concrete elements is the Finite Element Analysis (FEA). This study was, therefore, conducted to investigate the flexural behavior of reinforced concrete beam using a nonlinear finite element analysis through the application of the MSC MARC/MENTAT software program. This involved the use of a solid element to represent concrete while the truss bar was applied for reinforcing steel after which multi-linear and bilinear models were considered for the two elements respectively while embedded reinforcement model was applied to model the rebar. Moreover, the beam model was also studied and compared with experimental data from previous literature. The result showed the load-deflection to have significantly increased due to an increment in the steel reinforcement yield strength. The same was also observed for the concrete compressive strength while a decrease was recorded in deflection due to the reduction in the compressive strength because the strain was reaching the crushing value. Furthermore, the concrete tension model was found to be the same with the experimental results with the tensile strength observed to have lost its strength after reaching the tensile stress while the contact behavior of the modeled reinforced concrete beam showed the existence of a slip at the support and loading points.
