DESIGN OF RC CANTILEVER RETAINING WALL UNDER EARTHQUAKE CONDITIONS

Abstract

This investigation here gives us the analysis about the Retaining wall which is presents a comprehensive analysis and design methodology for reinforced concrete (RC) cantilever retaining walls subjected to earthquake conditions. Retaining walls are essential for slope stability and earth retention, especially in hilly or seismically active regions. The study integrates both manual and software-based approaches for analyzing wall stability under combined static and seismic loads. A Review of Research paper related to the design of RC Cantilever Retaining walls have been have also studied to get a deep insight analysis of the behavior of walls and also how to identify their interaction during the earthquake conditions. The methodology includes use of Excel for design calculations and STAAD Pro for finite element modeling. The wall design accounts for various load combinations including self-weight, backfill pressure, surcharge, and seismic forces as per IS 1893:2016. Earthquake effects are considered using Mononobe-Okabe theory for lateral earth pressures. There is also proper explanation of the staad file explaining the detailed material properties and load combinations acting on the structure and the result thereof. Results indicate that appropriate detailing and design consideration for seismic loads significantly improves performance. Every check has been performed for the structure stability and the design is than performed. The report concludes with recommendations for practical implementation and highlights the potential for future research in soil-structure interaction and time-history dynamic analysis and tells about the future scope which can be taken into account for making retaining walls more secure and safe. The references have also been attached for future references and studies to be performed.
