Performance Evaluation of G 12 RC Structures under Seismic and Wind Loading A Dynamic Analysis Approach

This study presents a comprehensive evaluation of the dynamic performance of a G 12 reinforced concrete RC structure subjected to seismic and wind loading conditions, focusing on a seismic Zone IV region with challenging aerodynamic effects. The investigation employs high fidelity finite element modeling FEM techniques to analyze critical structural parameters, including base shear, story displacement, inter story drift ratios, and modal frequencies. Seismic loading is assessed using the response spectrum method, while wind forces are evaluated via the static equivalent approach, in strict adherence to national design standards such as IS 456 2000, IS 1893 2016, and IS 875 2015. Key findings indicate that the structure demonstrates high resilience and compliance with safety and serviceability criteria, as maximum story displacement and drift ratios remain well within permissible limits. Modal analysis identifies a fundamental frequency of 1.5 Hz, with higher order modes exhibiting significant translational and torsional coupling, underscoring the necessity of torsional stability considerations in high rise design. Time history analysis further corroborates the seismic response, revealing peak top story accelerations of 0.35 g, aligned with the design input ground motion. Comparative wind load analysis confirms the aerodynamic stability of the structure, with minimal resonance effects. Additionally, non destructive testing NDT techniques, including rebound hammer and ultrasonic pulse velocity tests, validate concrete compressive strength and material integrity, ensuring structural robustness. The study underscores the indispensable role of advanced computational modeling, performance based design strategies, and empirical validation techniques in optimizing seismic and wind resistant high rise structures. The findings contribute significantly to the evolving paradigm of structural engineering, offering strategic recommendations for enhancing urban infrastructure resilience. Future research should explore the integration of high performance materials, energy dissipation mechanisms, and adaptive damping systems to further fortify multistory buildings against extreme dynamic forces.
