Introduction

In the world of bridge construction, the use of prestressed concrete has experienced significant progress. One of the latest innovations in this category is the use of Precast Double Tee Beam (PDT), which is designed as the main girder for the bridge. Although this technology is still rarely applied in Indonesia, in-depth study of its potential use can open up new opportunities in the construction of a medium span bridge. This article will explore the analysis of the prestress style in the Precast Double Tee and compare it with the Precast I Girder, which is a girder choice that is commonly used.

The Importance of Precast Double Tee Beam in Bridge Construction

Precast Double Tee Beam is one form of a cross-sectional concrete that has high strength and stability. The design allows the bridge to bear a large burden with minimal deflection, making it the ideal choice for the medium span bridge project. The pretension method (pretension method) in the analysis of the prestress force will be used to determine the amount of the required prestressing cable, as well as to analyze the deflection and loss of the prestressing force. The use of Precast Double Tee Beam can provide several benefits, including reduced construction time, improved durability, and increased safety.

Study Methodology

In this study, the author uses an analytical approach that refers to the standards that apply in Indonesia, such as planning concrete structures for bridges (RSNI-T-12-2004) and bridge loading standards (RSNI-T-02-2005). Data obtained from this analysis will not only provide an overview of the technical feasibility of using precast double tee but also evaluates the economy of its structure compared to precasts I girder. The study will also consider the environmental impact of using precast double tee, including the reduction of waste and the use of sustainable materials.

Analysis of Prestress Style

One of the main focus of this study is in the analysis of prestressing forces. In practical applications, the selection of size and number of prestressed cables greatly affects the performance of the bridge. With the Pratarik method, the author will calculate the required prestressable force and evaluate the maximum deflection generated by the load applied. The results of this analysis are expected to show that the Precast Double Tee Beam offers performance that is not inferior to I Girder, as well as indicating the potential to reduce construction costs.

Comparison with Precast I Girder

As a comparison step, Precast I Girder, which has been widely used in Indonesia, will also be analyzed with the same scope. This evaluation aims to provide insight into differences in terms of strength, deflection, and costs that may occur between these two types of girder. The results of this analysis will provide added value for engineers and decision makers in choosing the most efficient type of girder for bridge projects in the future.

The Benefits of Using Precast Double Tee Beam

The use of Double Tee Beam precast in bridge construction shows great potential as an appropriate alternative for bridge girder in Indonesia. Through this study, the author seeks to judge not only the technical aspects, but also the economic aspect of the use of this girder. With the expected results of the analysis, it is hoped that precast double tee can be widely accepted, providing innovative solutions to the development of bridge infrastructure that is more efficient and economical in Indonesia.

Conclusion

The use of Precast Double Tee Beam in bridge construction is a promising innovation that can provide several benefits, including reduced construction time, improved durability, and increased safety. This study aims to provide a comprehensive analysis of the prestress style in the Precast Double Tee and compare it with the Precast I Girder, providing valuable insights for engineers and decision makers in choosing the most efficient type of girder for bridge projects in the future.
