Rahul S V –  Dual Degree in CE

Rahul Suresh Vishwakarma received his MS-Dual Degree in Civil Engineering. His  research work was supervised by Prof. Pradeep Kumar R.

Here’s a summary of  Rahul’s M.S thesis, Torsional behaviour of buildings on slopes due to lateral load as explained by him: 

Buildings on Hilly area mainly differ by building on flat ground only by its torsional Behavior if the Building  is symmetrical, regular and similar above the road level. The parameter which comes in the picture are-

  • Axial Force on the ground floor beams due to generation of base reaction resisting torsional moment.
  • Load Distribution among frames in terms of percentage or ratio.
  •  Rotation of the floors due to the loading and eccentricity of the structure very small rotation cannot be seen by eyes.

Risks obtained because of these parameters can be reduced with the use of bracings and walls, which helps in the enhancing the stiffness of the frame which leads to decrease the movement of the frame which further leads to decrease in  the twist value of the floor, then to made uniform load distribution and reduction in Base reaction caused due to torsional movement. Walls and Bracings must be carefully provided so the parameter values can be reduced.

The study is  extended by increasing the number of bays in ridge direction and studying both cases with bracings and without bracings and saw that with bracing buildings are behaving quite well with decreased twist value and proper load distribution. This parameters like Twist and axial force on the ground floor beams are seen to be decreasing with increasing number of bays and it is found that the load distribution is almost same and their isn’t much difference with increasing number of bays so load distribution can only effected by using bracings and walls. All non -braced building have almost same load distribution and all braced buildings have almost same load distribution but better than non-braced buildings. When the slope is increased even in braced case building, loads taken by the shorter frame increases.
