How to solve A G $+3$ RC building is made up of MRFs in both X and Y directions. There are three bays of $6$m each in the X$-$direction and two bays of $5$m each in the Ydirection. All columns are $600$mm $\backslash$times $230$mm$,$ with the depth of column along Ydirection. All beams are $530$mm $\backslash$times $230$mm$.$ A RC shear wall of $230$mm is provided in the middle bay along X$-$direction only in the peripheral frames. Ignore the stiffness of infill masonry walls in the frames. Loads: Imposed loads on floors $4$ kN$/$m$2$ on floors and $2$ kN$/$m$2$ on the roof; Dead loads: to be calculated. The grade of concrete used is M$25$ and grade of steel is Fe$500.$ i$)$ Estimate the earthquake loads as per IS $1893$: $2016$ if the building is located in zone IV and is founded on clayey soil of intermediate compressibility with SPT $=8$ ii$)$ Write the assumptions made in the analysis $.$

calculate mass and stiffness for the above
