Design a welded compression member composed of double standard channels, placed face to face, using A36 steel. Length of the member is 7.5m and the maximum compressive factor force is 3R KN. Distance between centroid of the channels is to be 300mm. Design the section, end plates and the lacing system K=1.0

ANSWER:--
COMPRESSIVE FACTOR FORCE:-- The compressibility factor (Z), also known as the compression factor or the gas deviation factor, is a correction factor which describes the deviation of a real gas from ideal gas behaviour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.
CENTROID:-- the center of mass of a geometric object of uniform density
