Dynamic Behavior and Natural Frequency of a Geodesic Dome Comparison between Physical and Computational Models with Recycled Plastic

Abstract

This research analyzes the dynamic behavior of a geodesic dome constructed with recycled polypropylene type 5, focusing on determining its natural frequency. A combined approach of computational simulations and experimental testing was employed. A computational model was developed with specific mechanical properties of the material, serving as a basis for comparison with a physical prototype. The dome was subjected to vibration tests to measure its dynamic characteristics. The experimental results were compared with the simulations, revealing minimal discrepancies attributed to model idealizations and real construction conditions. This study validates the technical feasibility of using recycled plastic in geodesic structures, highlighting its potential to promote sustainable and innovative construction practices. Additionally, it emphasizes its alignment with the principles of the circular economy, fostering material reuse and reducing environmental impact, contributing to the development of conscious and efficient construction alternatives.
