Evaluating the impact of V-shaped columns on the dynamic behavior of RC buildings on sloped ground

Abstract

This study investigates the structural performance of multi-story reinforced concrete buildings on sloped terrains, with a focus on comparing standard normal column, normal columns with shear wall and V-shaped column configurations. The various parameters analysed include story shear, maximum displacement, story drift, stiffness variation, and time period, all of which are crucial for understanding the dynamic behaviour of structures under various conditions. The results indicate that V-shaped columns significantly enhance structural stability, particularly in reducing maximum displacement and story drift, and in improving load distribution, as compared to standard columns. In a 10-story building with a 10-degree incline, V-shaped columns exhibited a maximum displacement of 13.582 mm, lower than the 22.697 mm observed in standard columns. The analysis also reveals that V-shaped columns maintain consistent performance across different incline angles and story heights, demonstrating their efficiency in controlling lateral movement and managing shear forces, especially in taller structures. The study also shows that time periods are generally shorter for models with V-shaped columns, indicating better dynamic performance. The findings suggest that V-shaped columns are preferable for the design of multi-story buildings on sloped terrains, offering superior stability, load management, and overall structural efficiency.
