Analysis of the Use of Secant Pile with the Element Method to the Sapadia Medan Hotel Project

Introduction

The construction of the Sapadia Hotel project in Medan, Indonesia, has utilized a 60 cm diameter secant pile as a basement wall. To ensure the stability of the construction, it is crucial that the secant pile can withstand deformation during the basement construction process. This study aims to compare the results of the analysis using the element method (FEM) with direct observation in the field of lateral and vertical deformations that occur. Additionally, this research discusses the comparison between the results of analytical calculations with the element method to the maximum moment that occurs, as well as analysis of changes in soil character due to basement excavation activities.

Research Methodology

The analysis process begins with modeling the secant pile and basement excavation. The initial steps include processing soil data, identifying correlation, and determining relevant parameters. After that, the analysis was carried out with the help of FEM software. The analysis of this study shows that analytical calculations using empirical formulas produce a bending moment of 148.32 kN/m/m at a depth of 6.7 m. Meanwhile, the results of the analysis using FEM showed a bending moment of 143.95 kN/m/m at the same distance from the ground surface.

Understanding the Element Method

The element method, also known as the finite element method (FEM), is a numerical technique used to solve partial differential equations. In the context of civil engineering, FEM is used to analyze the behavior of structures under various loads. The method involves dividing the structure into smaller elements, each with its own set of nodes and degrees of freedom. The behavior of each element is then analyzed, and the results are combined to obtain the overall behavior of the structure.

Measurement and Analysis Results

Measurement in the field records a lateral deformation of 0.51 cm and a vertical deformation of 0.00 cm. Conversely, the analysis by the FEM method shows a lateral deformation of 0.18 cm and vertical deformation -0.12 cm. From these results, it appears that the maximum moment that occurs between analytical calculations and modeling with the element method to have insignificant differences. The same thing can be seen in the ratio of horizontal and vertical deformation between the measurement results in the field and modeling with the element method up.

The Importance of Soil Character Analysis

Through analysis using the element method to, it is found that basement excavation activities can cause changes in soil characteristics, which include horizontal and vertical deformation, as well as changes in stress, strain, and water pressure. A better understanding of this change is important, because it can affect the stability and safety of the building structure that is being developed. The analysis of soil character changes can provide valuable insights for engineers to design a safer and more efficient solution in infrastructure development.

Comparison of Analytical Calculations and FEM Results

The results of this study show that the element method is an effective tool in predicting the bending moment and deformation that occurs in the structure of the secant pile. The analysis using FEM software provides a clear picture of changes in the character of the soil due to the excavation of the basement. The results of this study function as a useful reference for planning and implementing similar construction projects in the future.

Conclusion

In conclusion, this study has demonstrated the effectiveness of the element method in predicting the behavior of secant piles under various loads. The analysis using FEM software provides a clear picture of changes in the character of the soil due to the excavation of the basement.
