Architectural/Structural Steel Drawings, ContinuedShapesBEARING PILES: Bearing piles are the same as wide-flange H-beams, but(Continued)are much heavier per linear foot.ZEE: These shapes are noted by depth, flange width, and weight per linearfoot.PLATES: Plates are noted by width, thickness, and length.FLATBAR: Flat bars are similar to plates with edges rolled square. Thedimensions are given for width and thickness.TIE ROD AND PIPE COLUMN: Tie rods and pipe columns are designatedby their outside diameters.MembersThe main parts of a structure are the load-bearing structural members thatsupport and transfer loads on the structure while remaining in equilibriumwith each other. The places where members connect are called joints. Thetotal load supported by the structural members at a particular instant is equalto the total dead load plus the total live load. The ability of the earth tosupport a load is called the soil-bearing capacity.TOTAL DEAD LOAD: The total dead load is the total weight of thestructure, which gradually increases as the structure rises and remainsconstant after the construction is completed.TOTAL LIVE LOAD: The total live load is the total weight of moveableobjects, such as people, furniture, and traffic that the structure supports atany particular time.Continued on next page4-13
