---------------------------------------------------------------------***--------------------------------------------------------------------requirements and cost implications under standard bridge Abstract - This study carefully compares Prestressed
loading conditions. The aim is to provide a valuable framework for engineers to make informed design decisions by aligning project-specific geometric and budgetary needs with detailed technical and economic insights.
Concrete (PSC) and Ultra-High-Performance Concrete (UHPC) girders for a 30-meter simply supported span. The main goal is to assess how each material affects the size requirements and the related costs under typical bridge loading conditions. This evaluation provides a solid base for engineering professionals, giving them useful data to guide important design choices. The research looks at the trade-offs of each material option, offering practical advice for choosing the best one. By matching a project's specific size and budget needs with the insights given, this study aims to help with making smart material choices for bridge superstructure design.
2. LITERATURE REVIEW 1.Syed Sofiya et al. (2023) This study uses STAAD.Pro to compare RCC and PSC T-beam girders for a 50m bridge. Results show the PSC girder is superior, with significant reductions in bending moment (32.91%), shear force (18.18%), and deflection (13.22%).
Key Words: Comparative Analysis, Economic Feasibility, Bridge Superstructure, Prestressed Concrete (PSC), UltraHigh-Performance Concrete (UHPC), Girder.
2.Yang Hang (2022) This review analyzes the interface between UHPC and normal concrete (NC). It finds the UHPCNC bond has excellent mechanical and durability properties, far exceeding NC-NC interfaces, due to UHPC's fibers and treatment.
1.INTRODUCTION Bridge infrastructure is fundamental to transportation networks, requiring designs that balance safety, economy, and durability. This study presents a comparative analysis between two distinct material technologies for a standard 30-meter simply supported I-girder: conventional Prestressed Concrete (PSC) and innovative Ultra-HighPerformance Concrete (UHPC). PSC is a proven workhorse, valued for its reliability and cost-effectiveness in achieving long spans through pre-compression. Conversely, UHPC offers exceptional strength and durability, enabling more slender, lightweight designs with potentially enhanced longevity. This research evaluates both systems under identical loading conditions, focusing on critical performance metrics including flexural and shear capacity, serviceability deflection, crack resistance, and material efficiency. The objective is to provide a clear, practical comparison of their structural behavior, moving beyond theoretical advantages to assess tangible trade-offs. Ultimately, this work aims to deliver actionable insights for engineers, supporting informed material selection in pursuit of more efficient and sustainable structural solutions.
3.Prashansha Sanjay Jaiswal et al. (2021) A manual design study for a 30m span shows PSC girders require drastically less material than RCC: 167.67% less steel and 46.52% less concrete, proving its economic and structural efficiency. 4.Govind H. Dake et al. (2021) This paper explores using granite dust to improve concrete properties. Adding granite dust increases strength, reduces porosity and water absorption, and enhances the overall density and durability of the concrete. 5.Sharma Debraj et al. (2021) This practical paper details the construction of precast PSC I-girders, covering mix design, cable profiling, and post-tensioning procedures as per Indian codes, providing valuable on-site implementation data. 6.Murugan M et al. (2020) This review highlights UHPC's exceptional strength (>150 MPa) and durability but notes its high cost in India. It concludes that despite the initial expense, UHPC offers long-term benefits from a longer lifespan and reduced maintenance.
1.1 Objectives
7.Rahul Gangwar et al. (2020) A STAAD.Pro analysis across spans (20m-30m) finds PSC girders are more economical for spans over 25m, offering a 17% cost saving at that length, while RCC is suitable for shorter spans.
The core objective of the research is to conduct a comparative structural assessment of Prestressed Concrete (PSC) and Ultra-High-Performance Concrete (UHPC) girders for a 30meter simply supported span. This analysis focuses on evaluating the influence of each material on dimensional
