Width of seat plate width of beam flange +2sw
1. thickness of seat plate flange thickness of beam bearing length of seat plate $\frac{R}{tw\times\frac{fy}{ymo}}$
2. Stiffner plate 1 thickness of stiffning plate $\lt$ tw(thickness of webb of beam) 2 . depth of stiffning plate d$\lt$18.9...IS pg 18 d$\lt$ 18.9t provide stiffning plate
3. size of weld resultant strength = strength of weld =Leff$\times E.T.T\times \frac{fu}{\sqrt{3}\times ymw}$ =Leff$\times(0.7\times sw)\times\frac{fu}{\sqrt{3}ymw}$ resultant strength =$\sqrt{q_{1}^{2}+q_{2}^{2}}$ $q_{1}$=verticle shear stress/mm=$\frac{R}{Lw\times sw}$ $q_{2}$ horizontal shear stress/mm=$\frac{m.y}{Ixx}$ m=p.e y=distance of Cg to extreme fiber to Ixx=MI
4. Provide cleat angle 100$\times$100$\times$8mm and connect using 4 mm fillet weld
