Numerical Validation of Floor Plates Due to Concentric Axial Loads Using the Steel Stress-Strain Model Approach in Abaqus Software

Abstract

This study aims to validate the numerical model of plates without openings (S1) and plates with central openings (S2) due to concentric axial loads using the ABAQUS-based Element Up Method. The model is developed with a nonlinear approach, then calibrated and verified against the results of previous research. The results of the load deflection curve calibration showed a percentage difference of 9.1% for S1 and 3.1% for S2, which is still within the tolerance limit. Comparison of the deformation distribution shows a maximum value difference of 3.2% (S1) and 1.2% (S2). There are differences in the visualization of the contour deformation that occur due to the difference in the condition of the elements and the modeling approach. The damage pattern in the S2 model shows similarities to the experimental results carried out. Overall, the numerical model developed has a good level of accuracy and validity and is suitable for advanced analysis of open plates.
