We invite you to participate in an exciting simulation challenge focused on modeling a complex structure composed of two differently sized octagons connected by trusses.
Objective: Model and analyze a structure consisting of two octagonal frames (one larger and one smaller) connected by vertical trusses. The goal is to explore how the geometry, material properties, and loading conditions affect the structural performance.
- Structure Design: Two Octagons:
- Top Octagon: Size: Larger octagon with a side length of 2 m. Height: Positioned 5 m above the ground.
- Bottom Octagon: Size: Smaller octagon with a side length of 1 m. Height: Positioned at ground level (0 m)
- Trusses: Connect each vertex of the top octagon to the corresponding vertex of the bottom octagon using trusses.
- Truss Design: Define the cross-section for the vertical trusses (e.g., circular or rectangular).Ensure that the trusses are evenly spaced along the edges of both octagons.
- Material Properties: Select an appropriate material for the structure Define material properties such as Young's modulus, Poisson's ratio, and yield strength.
- Model Setup: Create the geometry using appropriate modeling techniques (e.g., sketching for octagons and extruding for trusses).Ensure that all connections between the octagons and trusses are properly defined to simulate a continuous structure.
- Beam Orientation: Define the local coordinate system for each vertical truss element carefully. Assign beam section orientations based on their respective local axes.
- Applying Loads and Boundary Conditions: Apply realistic loads to your structure, such as: Uniformly distributed loads on the top octagon to simulate weight. Lateral loads representing wind or seismic forces. Set boundary conditions that reflect realistic constraints (e.g., fixed supports at the base of the bottom octagon).
- Running the Analysis: Execute the analysis in Abaqus, Ansys or Any software of your choice.
- Post-Processing: Analyze results by examining displacement contours, stress distribution, and reaction forces at supports. Investigate how different loading scenarios affect structural performance.
- Documentation Submission: Prepare a comprehensive report summarizing your modeling process, findings, and reflections on the challenge. Include screenshots of your model setup, results (e.g., stress plots, displacement contours), and any relevant calculations.
- Eligibility: Open to anyone interested in finite element analysis.
- Submission Deadline: All submissions must be received by 5th November
- Judging Criteria: Submissions will be evaluated based on accuracy, clarity of documentation, depth of analysis, and creativity in approach.
