The Effect of the Use of Glass Fiber Reinforced Polymer in the Brick Column

Columns are a crucial structural element in buildings, responsible for supporting axial loads, bending moments, and shear forces. To enhance the strength and durability of columns, modern technology offers various reinforcement methods, including the use of Fiber Reinforced Polymer (FRP). Among the types of FRP, Glass Fiber Reinforced Polymer (GFRP) stands out due to its exceptional characteristics, such as high stiffness, optimal strength, and ease of installation. This study aims to investigate the effect of using GFRP in reinforcing brick columns, with a focus on analyzing the axial capacity building of the column.

Columns are a fundamental component of building structures, and their ability to withstand loads and pressures is critical to ensuring the safety and stability of the entire structure. The use of traditional materials, such as steel and concrete, has been the norm in column reinforcement. However, these materials have limitations, including high weight, corrosion susceptibility, and the need for complex installation processes. In contrast, GFRP offers a lightweight, corrosion-resistant, and efficient solution for column reinforcement.

In this study, brick columns measuring 22 x 22 cm and 100 cm high were constructed using a combination of bricks and mortar. The columns were then reinforced with GFRP, which was applied externally to provide additional support and stability. The study aimed to analyze the axial capacity building of the column, with a focus on determining the compressive strength of the reinforced column.

From theoretical analysis, it was found that the application of GFRP can increase the compressive strength of the brick column by up to 30.02% compared to the initial strength. This increase in compressive strength is attributed to the high stiffness and optimal strength of GFRP, which provides additional support and stability to the column.

The test results carried out on the reinforced columns showed an increase in real compressive strength of 29.41%. This result is consistent with the theoretical analysis, indicating that the application of GFRP can significantly enhance the compressive strength of the brick column.

The use of GFRP in reinforcing brick columns offers several advantages, including:

Increased capacity: GFRP provides additional support and stability to the column, enabling it to withstand greater loads and pressures.
Crack prevention: GFRP helps to prevent cracks that can occur due to loads and pressures, ensuring the column remains stable and secure.
Lightweight: GFRP is a lightweight material, making it easier to install and transport compared to traditional materials.
Corrosion-resistant: GFRP is resistant to corrosion, reducing the risk of damage and extending the lifespan of the column.
Cost-effective: GFRP is a cost-effective solution for column reinforcement, reducing the time and cost of construction.

In conclusion, the use of GFRP in reinforcing brick columns has a significant positive effect on the strength and stability of the structure. The application of GFRP can increase the compressive strength of the column by up to 30.02%, and the test results showed an increase in real compressive strength of 29.41%. The advantages of GFRP, including increased capacity, crack prevention, lightweight, corrosion-resistant, and cost-effective, make it an attractive solution for column reinforcement. This study highlights the potential of GFRP in enhancing the durability and stability of buildings, and its use is expected to become more widespread in the future.

Based on the findings of this study, the following recommendations are made:

Widespread adoption: GFRP should be widely adopted as a material for column reinforcement due to its exceptional characteristics and benefits.
Further research: Further research is needed to explore the potential of GFRP in other applications, such as beam and slab reinforcement.
Standardization: Standardization of GFRP production and installation processes is necessary to ensure consistency and quality in the use of this material.

This study has several limitations, including:

Small sample size: The study was conducted on a small sample size of brick columns, which may not be representative of larger-scale applications.
Limited scope: The study focused on the axial capacity building of the column, and further research is needed to explore other aspects of GFRP reinforcement.

The findings of this study highlight the potential of GFRP in enhancing the durability and stability of buildings. Future research should focus on exploring the potential of GFRP in other applications, such as beam and slab reinforcement, and developing standardized production and installation processes for this material.
