Slab I.D. 2S-1
LENGTH: 3500 mm Main barØ: 12 mm
Fc': 21 Mpa temp. barØ: 10 mm
Fy: 275 Mpa
min. "t" req'd = 138.75 mm
use slab thickness = 140.00 mm
INPUT DATA:
Super Imposed Dead Load (SDL) = 1.8 kPa
Live Load (LL) = 2.4 kPa
OUTPUT DATA:
Slab Selfweight = 3.36 kN/m
therefore, factored load on 1 meter strip,
W = 1.2*Self weight + 1.2*SDL + 1.6*LL 10.03 kN/m
Mmax. = 15.36 kN-m ρ min. =0.00509
Vmax. =17.56 kN ρ max =0.02837
ρ bal. =0.04 ρ reqd. =0.00497 use ρ = 0.00509
DESIGN:
ρ reqd. < ρ max therefore,
Check for Shear, Vu is critical at "d" distance from the support
Vu = 16.41 kN
actual V = 0.17 Mpa
allow. V = 0.78 Mpa
actual V < allow. V therefore,
DESIGN OF REINFORCEMENT:
As min. = 0.0020bt 280
mm2
As req'd. = ρbd 580.36
mm2NOTE:
For Main reinforcement, "s" should not be
greater than 3*t
use 12 mm dia. use 10 mm dia. ForTemp. reinforcement, "s" should not be
@190 @280 greater than 5*t nor
greater than 450 mm
