Abstract

This dissertation investigates the enhancement of cracked column resistance against buckling through the application of carbon fibre. Columns, crucial for structural stability, are vulnerable to buckling due to cracks induced by various factors. Carbon fibre reinforcement presents a promising solution, offering high strength-to-weight ratios and compatibility with structural materials.
The study's aim is to assess carbon fibre's effectiveness in increasing cracked column resistance against buckling using LUSAS software for structural analysis. Objectives include understanding cracked column behaviour under buckling loads and evaluating carbon fibre's impact on buckling resistance.
Utilising modelling cracked columns and applying carbon fibre reinforcement using different layers and lengths. Results show significant improvements in buckling resistance with increasing layers of carbon fibre. Additionally, the relationship between carbon fibre length and buckling resistance is examined, with optimal results achieved with one layer at a length of 250mm.
The analysis underscores the effectiveness of carbon fibre in enhancing cracked column resistance against buckling, with implications for safer and more resilient structures. The study advocates for strategic carbon fibre application to minimize material usage while maximizing structural benefits, promoting sustainability in engineering practices.
