Bending and Experimental Analysis of Additional Concrete Quality in the Compressive Area of Reinforced Concrete Beams

Introduction

In the pursuit of creating strong, safe, and economical construction, it is essential to comprehend the mechanical characteristics of reinforced concrete beams. These beams experience pure bending when subjected to a load, reaching the collapse limit. In this condition, the compressive stress is distributed from a neutral line to the top fiber, while the tensile stress is held by steel reinforcement. In the structure of reinforced concrete beams, concrete functions to hold the voltage on the pressure, while the steel reinforcement plays a role in the tensile. Therefore, research on the addition of concrete quality in the reinforced concrete beam compressive area is highly necessary to increase the bending capacity.

Background

Reinforced concrete beams are widely used in construction due to their strength, durability, and cost-effectiveness. However, their performance can be affected by various factors, including the quality of concrete used. The compressive area of the beam is particularly crucial, as it bears the majority of the load. The use of high-quality concrete in this area can significantly impact the beam's bending capacity and overall performance.

Methodology

This study focuses on flexible testing conducted on two types of reinforced concrete blocks. The first is a normal reinforced concrete beam, where one concrete quality is used throughout the structure. The second is a layered reinforced concrete beam, which consists of two layers of concrete with different quality. In the first layer, the tensile section has the same concrete quality as a normal beam, whereas in the second layer, the pressure part uses higher concrete quality.

Experimental Setup

The experimental setup consisted of two types of reinforced concrete beams:

Normal Reinforced Concrete Beam: This beam was made with a single layer of concrete, with a uniform quality throughout the structure.
Layered Reinforced Concrete Beam: This beam consisted of two layers of concrete, with different quality. The first layer had the same concrete quality as the normal beam, while the second layer used higher concrete quality.

Results

The results of the test show that layered reinforced concrete beams have better performance compared to normal beams. The decline in deflection and strain in layered beams was recorded at 10.52% and 6.3%, respectively. In addition, an increase in bending capacity reached 6.25%. This finding indicates that the use of high-quality concrete in the reinforced concrete beam has had a significant effect in reducing deflection.

Discussion

The results of this study demonstrate the importance of using high-quality concrete in the compressive area of reinforced concrete beams. The layered reinforced concrete beam showed improved performance compared to the normal beam, with a significant reduction in deflection and strain. This finding suggests that the use of high-quality concrete in the pressure part of the beam can lead to increased bending capacity and improved overall performance.

Conclusion

This study contributes to the development of structural designs that are more efficient and reliable. The results of this study can be a reference for engineers in designing better reinforced concrete beams in the future. Further research is also recommended to explore the influence of other types of concrete mixtures and variations in structural design on the bending performance of reinforced concrete beams.
