TAPER COLUMN

 

 TAPER COLUMN

 

TO BE SLOPED FROM 450MM TO 200MM OR 250MM

 

THE COLUMN SHALL BE TAPERED FROM 450mm AT BASE TO 200mm AT TOP.

PIPE 450x6 and MAX H=13m.

Circum1 =   2×3.14×22.5 =  141.3  cm

Circum2 = 2×3.14×10 = 62.8 cm

Area 1= 3.14×22.5×22.5=1590cm2

Area 2= 3.14×100 = 314cm2

Slant Height (L) =\ /h2+ (R1-r2)2

=1300×1300+ (22.5 – 10 )2=1690000+156.25=1690156.25 cm2

=1300.06 cm

Slant area=3.14 L (R1+r2)

= 3.14×1300.06 (22.5+10 ) = 132671.123

Area Tapered = 3.14L(R2×R2+r1×r1 +R2+r1)

=3.14× 1300.06 ×( 22.5×22.5 +100+22.5+10 ) = 3.14× 1300.06  )×638.75) = 2607497.84cm2

Weight= 125kgm

Sheet =( 150cm×1350cm×6mm)× 8kg/m3 = 972kg.

Total weight = 1000kg.+100kg = 1100kg.

Base plate COLUMN (600X800) thik. 20mm = 80kg.

STIFFENER 8mm = 20kg.
