Nonlinear finite element analysis of abnormal exterior joints consist of Steel Reinforced Concrete column and Reinforced Concrete beam was performed using ABAQUS computation program, the joints failure mode and the skeleton curve were calculated. Comparison with experimental results to prove the reliability of finite element analysis. Then, the paper analyzed different parameters which affect the joints loading capacity, the results indicate that to a certain extent, the eccentricity of the upper and lower column sections and steel ratio both have important effects on the stiffness and ultimate loading capacity of the joints; with the increment of the ratio of axial compression, the joints ductility will be reduced.

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.
