According to BNBC 2006, page 10631,
T=Cn(hn)^(3/4)
=0.083*5.32^3/4
=0.083*5.32^3/4
=0.29 sec
C=(1.25*S)/(T^(2/3))
=(1.25*1.5)/(0.29^2/3)
=(1.25*1.5)/(0.29^2/3)
=4.28
V=(ZICW)/R
Dhaka is in zone 2, so, zone coefficient is 0.15
=0.15*1*4.28*W/6
=0.107W
W=Total seismic dead load
Dhaka is in zone 2, so, zone coefficient is 0.15
=0.15*1*4.28*W/6
=0.107W
W=Total seismic dead load
=Rafter weight (assume=0.5KN/m)*frame length+Column weight (assume=0.5KN/m)*nos of column*length of column+(purlin weight+sheet weight)*frame length
=0.5*11.66+0.5*2*5.32+0.66*11.66
=18.90 KN
So, V=0.107*18.90
=2.02 KN
According to BNBC 2006, page 10634
V-Ft=2.02 KN
So, Seismic load, F=2.02 KN
