Introduction

The suspension bridge of Pisang Binaya Village is a vital structure that connects the community to the rest of the region. The angkur block, a crucial component of the bridge, plays a significant role in supporting the backstay tensile loads. However, the concrete used in the angkur block has a lower tensile strength compared to its compressive strength, making it prone to failure under tensile loads. To overcome this weakness, steel reinforcement is necessary to provide high tensile strength to the concrete blocks. This study aims to analyze the voltage that occurs in the angkur block using the Ansys program, determine the optimal distance of reinforcement in the area with the maximum tensile stress (critical area), and evaluate the voltage distribution in the structure of the angkur block visually.

Background

The angkur block is a critical component of the suspension bridge of Pisang Binaya Village, and its adequate dimensions are essential to ensure that its strength exceeds the pulling cable pulling force. The structure of the angkur blocks in the village of Pisang Binaya already has a large dimension, but the concrete used has good compressive strength, with a tensile strength that is only about 10% of the compressive strength. This makes the concrete vulnerable to failure under tensile loads. To address this issue, steel reinforcement is necessary to provide high tensile strength to the concrete blocks.

Methodology

This research was conducted using a numerical approach, with the SAP 2000 program used to calculate the internal force in the entire suspension bridge structure. The ANSYS analysis program was then used to obtain tensile stresses that occur in the Angkur Block. The angkur block model in Ansys was created by paying attention to the field conditions as close as possible. The results of the Ansys analysis were then compared with the empirical analysis to determine the optimal distance of reinforcement in the critical area.

Results of Ansys Analysis

The results of the Ansys analysis showed that the maximum tensile stress occurs on the steel profile H 300,300.10.15 with a value of 80.582 MPa. Meanwhile, the maximum tensile voltage in the concrete is 0.41 MPa, which is still within a safe limit because it is lower than the permitted concrete tensile tension of 2.23 MPa. These results indicate that the steel reinforcement is effective in providing high tensile strength to the concrete blocks.

Results of Empirical Analysis

From the results of the empirical analysis, a maximum distance of reinforcement in the critical area is 300 mm, while in the non-critical area is 350 mm. This information can be used as a guide in the planning and construction of a stronger and more durable angkur block structure.

Discussion

The results of this study provide a more detailed picture of the behavior of the structure of the suspension of the suspension bridge of the Pisang Binaya Village. The analysis of Ansys and Empirical Methods used provides valuable information about the distribution of voltage and determining optimal reinforcement distance. The results of this study can be useful for engineers and practitioners in designing and building a safe, efficient, and durable angkur block structure.

Conclusion

By understanding the voltage that occurs and determining the proper reinforcement distance, we can ensure that the structure of the Suspension Bridge of Pisang Binaya Village can withstand the load safely and function well for a long time. The results of this study can be used as a guide in the planning and construction of a stronger and more durable angkur block structure.
