how the calculation is taken for shuttering in staircase?
1.(FLIGHT & LANDING) calculate each flight underside,landing underside area.landing underside area is normal L*B,but flight underside area calculate using formula (A*A + B*B=C*C)=length of flight then L*B=AREA .
2.(WASTE SLAB) calculate waste slab side ex.waste slab thickness0.150m flight length 3.8m=(both sides)2*3.8*.15=1.14sq.m.
3.landing sides=l*h(l=3sides)
4.(STEP) ex.width of staircase=1.25m,riser=.15m,threader.3m each flight13steps each flight calculation=width=1.25*13=16.25sq.m both sides =(0.15*.03*13)=0.585 sq.m because ((.15*.3)/2*2=0.15*.3)OK.
