Answer / mustafa mohammed layeak

Partial safety factor for concrete is 1.5 and for steel is
1.15 in limit state design. Minimun reinforcement for
column = 0.87% of the cross sectional column area.
Mininimum reinforcement in slab = 0.12% of c/s area (when
deformed bars are used) and if mild steel (Plain rounded
bars)is used then = 0.15% of c/s area of slab.

Answer / javed ather

F.O.S= 1.7 For concrete, 3 for steel.(working stress method)
partial f.o.s = 1.5 for concrete and 1.15 for steel.(limit state method)
min reinforcement = 0.8 % for column and 0.15% for slab.
min size of reinf = 12mm for column and 8mm for slab.

The building has 12 columns of 12x9 in 3 rows of 4 each in a plot of 50'x30', The central row is strengthened with 16mm twisted rods. The roof area is 1500 sft including balconies. calculate the load factor per sft. Also indicate the number of roofs the building can withstand.
