interaction between tall buildings and wind on flat and sloping ground, specifically focusing on the northern part of India with high wind flow. Reinforced concrete structures of different heights (G+5, G+10, and G+15) are analysed on both flat terrain and slopes (0°,10°,20°, and 30°) for various wind zones. Wind load analyses using the e-tabs software are performed in this paper there are 3 types of models has been done for the different zones. The story displacement, story drift, mode period has been also checked and result is satisfactory. Results from software and manual calculations are compared, and design considerations are based on maximum obtained values.
1.1 A Building Resting on A Flat Surface . In today's world, the expansion of cities and human colonies is causing our agricultural fields and villages to vanish. High-rise buildings play an important role in minimizing wasteful land use. A tall building or structure built for residential or commercial purposes is referred to as a high-rise building, apartment tower, office tower, apartment block, or block of flats.
Key Words: Wind analysis, building tower, Sloping Ground, wind load, wind analysis, high-rise structure, deflections, wind pressure.
1. INTRODUCTION Wind load is a critical factor in the design of structures and requires thorough investigation to understand its effects on buildings. Particularly, buildings constructed on hill slopes often possess unsymmetrical characteristics. This project focuses on conducting a comprehensive study of wind load behavior on building frames, analysing the structural response to wind, and assessing the impact of slope on the structures. Structural designs aim to withstand earthquakes, and wind loads, maintain stability, and prevent damage. Wind load acts as a lateral force on buildings, exerting pressure along and across the wind direction. In [IS 875 – (Part 3) – 2015], the basic wind speeds are specified and categorized by zones on a map. The shape and size of a building play a crucial role in wind analysis since wind pressure depends primarily on the exposed area of the building facing the wind speed.
Fig -1 Resting on A Flat Ground 1.2 An indicative R.C. Structure Resting on Inclined Ground Buildings resting on sloping ground present a unique set of challenges for structural engineers. The slope of the ground can cause uneven column heights, different soil conditions, and increased seismic risk. These challenges must be carefully considered in the design and construction of the building to ensure its safety and stability.
The analysis of structures becomes particularly critical when located on steep or sloping ground, especially in areas with higher wind flow intensity and hilly regions. Buildings constructed on hills using masonry with mud mortar or cement mortar, without conforming to seismic codal
