determine the fixed-end column made of circular bar of aisi 1020 hot-rolled steel. the diameter of the bar is 20 mm and length is 800 mm. sy= 331 mm4 E=207N/mm2

Solution

for 1020 hot-rolled steel,   E=207*1000 N/mm2

Pc=(pi^2*EI)/L^2

=((pi^2)*(207000)*(pi *d^4/64)) /800^2

=((pi^2)*207000*(pi *20^4/64)) /800^2

=25.0714 kN
