Effect of wind on RC structure resting on sloping ground and analysis done using ETABS software

Wind load is one of the common loads for civil engineering structures viz. for long span bridges, tall buildings, towers and mast structures also. Wind load is acting on such structure throughout its life span. Therefore it is most important phenomenon to be taken into consideration for a structural engineer. Due to scarcity of land or due to mountainous terrains in North and North-East part of India most of the time structures are constructed on sloping grounds which is a challenge for structural engineer for analysis and design. These structures are also directly subjected to wind loads. India is also having large records of earthquake which left behind loss of many lives and heavy destruction to property and economy. Analysis of buildings in hilly regions with sloping grounds is somewhat different than the building located over a levelled ground. In present study 3D building frames of 25 storied building resting on flat terrain and sloping ground are taken into consideration. For sloping ground slopes of 20⁰,30⁰, and 40⁰ are considered. They are to be analyzed for wind speeds 39 m/s, 47 m/s and 55 m/s respectively. The modelling and analysis can be done using ETABS software which stands for extended three dimensional analysis of building system.
