STEEL AS A STRUCTURAL MATERIAL 1.1General Structural steel is a material used for steel construction, which is formed with a specific shape following certain standards of chemical composition and strength. They can also be defined as hot rolled products, with a cross section of special form like angles, channels and beams/joints.

characteristic behavior of the construction materials and the design details of the buildings. The very fact that the buildings survived the crash of the planes into the buildings s uggests that a time dependent behavior at the material level affected the structural stability of the structure to the point of failure.
