Effect of Addition of Glass Fiber Reinforced Polymer Strengthening in Round Column

Introduction

Columns are a crucial structural element in building construction, providing support and stability to the entire structure. With the increasing use of concrete structures over steel structures, due to their higher efficiency and lower costs, the need for reinforcement in concrete columns has become a pressing issue. The failure of concrete columns is a common problem, and one of the popular methods to overcome this issue is by using Fiber Reinforced Polymer (FRP), specifically Glass Fiber Reinforced Polymer (GFRP). This study focuses on the comparison of the compressive strength of concrete without reinforcement with the addition of GFRP as an external reinforcement in a concrete column measuring 15 x 80 cm.

Theoretical Analysis and Experimental Results

The theoretical analysis results show that the strength of the column strengthened by GFRP increased by 42.035% compared to normal concrete compressive strength. Meanwhile, the experimental results also revealed that the strength of the column reinforced by the GFRP increased by 35.29% of the normal concrete compressive strength. These results indicate that the addition of reinforcement using GFRP can increase the ability of the column to withstand a larger axial compressive strength compared to columns that are not strengthened.

Benefits of Using GFRP in Column Strengthening

The addition of GFRP in column strengthening is not only beneficial in reducing the risk of structural failure but can also extend the service life of the building. GFRP has superior properties, such as mild, corrosion-resistant, and high flexibility, making it an ideal choice for column strengthening. The use of GFRP in construction is also in line with the development of composite material technology, which is increasingly applied in various fields of civil engineering. This advantage provides added value for the designer and contractor in designing buildings that are more durable and efficient.

Environmental and Sustainability Benefits

Taking into account environmental factors and sustainability, the use of materials such as GFRP also supports construction practices that are more environmentally friendly, as it can reduce the use of heavy materials such as steel. The use of GFRP in column strengthening is a step towards a more sustainable and environmentally friendly construction industry.

Conclusion and Future Research Directions

In conclusion, the use of Glass Fiber Reinforced Polymer as a reinforcement in a round column provides an efficient and effective solution to increase structural strength. Further research can also explore various other aspects of GFRP in its application in the field of civil engineering, including cost analysis and long-term impact on structure performance. This technical adoption is expected to help improve the safety and efficiency in future building construction.
