Introduction:

It may be observed that for steel having fy = 250 MPa, the value of allowable σac becomes 33 MPa only, for the maximum permissible slenderness ratio of 180, being thus reduced by 87%

 

Description:

 

The direct stress in compression on the gross-sectional area of axially loaded compression members shall not exceed 0.6 fy nor the permissible stress σac, calculated using the following formula :
