Answer / sujit

calculating load factor
incase of astructure some live load and dead load is
calculating
As per IS code - take live load-4.0 kn/Sqm
terrace finish- 1.5 kn/sqm
floor finish - 1.0kn/sqm
water proofing- 2.0 kn/sqm
----------------------------
total load-8.5 kn/sqm
i conver all ft ad inch to mt and mm
dead load of column or its own weight-
.38x.228x25x12=25.992kn/m 25kn/m recc wight
beam weight- .304x.304x25x15.732x3=109.041
- .304x.304x25x29.5x4=272.62
slab weght- 222.22x.100x25= 555
------------------------------------------------------
total weight= 962.653kn/sqm

total dead load+ live load=962.653+8.5 = 971.153kn/sqm
so per sqm load factor = 971.153 kn /sqm
you can easily convert it per sqft
