Structural Steel System Isometric View

SAMPLE STRUCTURAL STEEL SYSTEM

The structural steel system uses panels, columns, beams, trusses and decking to enclose a building.
Trusses are usually placed to span the shortest measurement of a building and are classified as either end - ET (one at each end of the building) or interior - IT (all within the exterior walls of the building. End trusses usually hold up less weight.
Beams are usually placed along the longest measurement of a building and classified as exterior - XB (sit on exterior walls of building) or interior - IB (set in the middle of building). Interior beams are usually used when interior columns do not interfer use of the building.
Columns are placed at the corners (corner columns - CC) of a building and at the points where the modular grid intersects the long outer walls (exterior wall columns - XC). Additional columns may be placed in the center of the end walls (end wall columns - EC) and along a central modular grid line for the length of the building (interior columns - IC).
