DESIGN OF STEEL TRUSS PURLIN STRUCTURE

Structural steel is steel construction material, a profile, formed with a specificshape or cross section and certain standards of chemical composition and mechanical properties. Structural steel shape, size, composition, strength, storage, etc., is regulated in most industrialized countries.

Structural steel members, such as I-beams, have high second moments of area, which allow them to be very stiff in respect to their cross-sectional area.

If you have a steel structure book  then you can design any kind of steel structure.

below i describe some book.

also for you describe some image of steel structure details
