Enhancing Dam Resilience : Addressing Both Seismic and Non-Seismic Influences

This study explores the application of SAP2000 software in the analysis of hydraulic structures, specifically dams, a field where its use has been limited until now. By evaluating a hypothetical concrete gravity dam section under various loading conditions, including seismic forces, the research compares SAP2000 with traditional numerical evaluation methods. The study involved detailed stress distribution and deformation analysis using SAP2000 and intricate structural behaviour calculations through numerical assessment. Results showed that discrepancies between the two methodologies ranged from 0 to 5%, demonstrating SAP2000's reliability. Comprehensive assessments included dam stability, stress distribution, and seismic response, revealing a maximum moment of 21493.02 kN.m at the base under typical operating conditions and a total pressure of 745.53 kN under seismic conditions. Stress and strain contour plots from SAP2000 visualized complex interactions, enhancing understanding of structural responses and identifying compromised safety factors due to tensile stress under seismic conditions. The findings emphasize the importance of using advanced software tools for accurate and efficient dam analysis. The study concludes that integrating SAP2000 provides a robust tool for engineers, complementing traditional numerical methods and advancing the state of practice in dam engineering. This research significantly contributes to the design of resilient concrete gravity dams capable of withstanding both standard and seismic forces, ensuring their safety and stability.
