Abstract

The anchorage system is one of the techniques used to connect a new structure to the existing structure. The purpose of this study was to determine the behavior between the anchorage connection model in the existing column structure and the new beam using an adhesive anchoring system, and the monolithic column-beam structure model using a program based on the finite element method, Abaqus CAE. The analysis was executed on two models, the monolithic construction model and the anchor joint connection structure model. The same load was applied for both models at the ends of the beams. In the monolithic construction model, the interaction relationship between the column and beam is using a tie constraint, while the structure of the anchor joint connection was using surface-to-surface contact. The epoxy model in anchor joint structure were using a cohesive behavior-contact relationship. As the results of the analysis, it can be concluded that the monolithic construction has stiffer joints compared to the structures with anchor joint connections, it can be seen from the displacement value of monolithic construction is 4.263 mm meanwhile structure with anchor connection is 5.38 mm. The crack pattern in the monolithic construction is in the column face on the area around the beam connection, while in the anchor connection, the crack pattern forms a cone in the area around the column anchor.

Abstract

Development in Indonesia continues to increase in line with growing community needs. In South Sumatra Province, one of the projects currently underway is the Kayu Agung – Palembang – Betung Toll Road. This study is expected to contribute to the development of Lean Construction methodology in Indonesia and provide practical recommendations for other infrastructure projects. The application of Lean principles in this project has significant potential to reduce waste and improve efficiency. The results of the study show that out of eight categories of waste, seven types of waste were identified. The two most dominant were Defects (24.14%) and Waiting (20.69%). The dominance of Defects indicates weaknesses in quality control, which leads to rework, cost overruns, and reduced resource efficiency. Meanwhile, the high level of Waiting illustrates a lack of synchronization in the workflow due to delays in material supply, ineffective coordination, and slow decision-making. The combination of these two factors has a direct impact on decreased productivity, schedule delays, and increased budgets. Therefore, this study emphasizes the need for stricter quality control and time management strategies through the application of Lean Construction principles.
