To make sure that the structure bear, all types of loads affect the structure, such as the structure’s self weight, dead loads, live load and seismic loads and its crash action on the structure such as seismic and wind force. The Grade of concrete used in the structure is one of the major parameters to guarantee strength & stability of the structure.  The primary step in construction is the sub structure that rest on the subsoil beneath. The soil has diverse properties and phases in it. According to the Indian earthquake code, the soil can be soft, medium and hard soils. It can also be classified by zones. Therefore, structural requirement is  to analyze the structure of the four diverse soil types, as the geography and layers of the soil surface differ according to the site conditions.

In this research the impact of Grade of concrete can be advantage to guarantee 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 structure.  A concrete up gradation or concrete belt is used in the structure on the 6^th, 7^th ,8^th 9^th & 10^th  floor of the building. The collision of Concrete belt is analyzed in soft soil. The outcome are based on the maximum Displacement, base shear, bending moments, Torsional moments & Stresses. The project concluded that The Structure Models case PP2 (6^th floor beam M- 40 Grade of Beam) Show the most favorable Strucure with All 6^th floor beam M- 40 Grade of Beam. The importance of basis structure conctruction is used as M-40 grade concrete belt with 6 th floor, at plinth, all structre with M25 grade of concrete and then at the top floor(18 th floor) in decrement order.
