To ensure that the building faces, all loads affect the building, such as the structure’s own weight, live loads, and lateral loads and its impact action on the structure such as earthquakes and wind force. In this project, the impact of Grade of concrete can be asset to ensure the stability of multi storey building. A G+16 Storey building having a plane area 576 m2. The two types of grade of concrete i.e. M25 & M40 is used in the building.  A concrete up gradation or concrete belt is used in the structure on the 8th & 16th floor of the building. The Impact of Concrete belt is analyzed in soft, Medium & Hard soil. The results are based on the max. Displacement, base shear, bending moments, Torsional moments & Stresses. The project concluded that The Structure Models ASI 3,6,9 (All 8th floor beam M- 40 Grade of Beam) Show the optimum Structure with All 8th floor beam M- 40 Grade of Beam. The priority basis structure construction is used as M-40 grade concrete belt with 8th floor, at plinth, all structure with M25 grade of concrete and then at the top floor(18th floor) in decrement order. If N no. of storey is there than the concrete belt with change in grade is best placed at the position of N/2 Storey. Soft Soil Exhibits less parametric magnitude value and it goes in increment mode in the medium and hard soil.
