Base Shear Reduction by Using Optimum Size of Beams in Top Floors with Different Grades in Multistoried Building at Different Levels

The recent development shows that expansion is the key to enlarge the infrastructure not only in horizontal direction but in vertical direction too. For this, tall constructions are favored due to less consumption of the land region for living purpose. With this, the seismic disaster activities in this approach made it more complicated. Indian Standard code of practice 1893:2016 shows the seismic prone zones where the shakes are witnessed. On decreasing the load of the structure decreases the Base Shear on the foundation base without compromising the stiffness of the tall structures. To demonstrate and prove this, six tall structures are prepared using software approach, lessening the beam sizes with grade change in top floors, analyzed it and compared among them. After deep comparative analysis, it has been found out that Building with Base Shear reduction case F1 emerges and hence proved to be the best Base Shear reduction case.
