5 5 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Wood Construction Many different types of wood are used as structural timber The surface of a wood product is finished by milling or planing Due to wood loss in surfacing, nominal size is larger than dressed thickness Symbols are used to indicate requirements for finished surfaces on wood

6 6 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Wood Joints

8 8 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Structural Steel Structural steel drawings are ordinarily one of two types: Engineering design drawings Manufacturing (shop) drawings

9 9 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Structural Steel Engineering design drawings show the overall dimensions of the structure including: Locations of columns, beams, angles and other shapes Sizes of structural members Detail in the form of cross sections, special connections required, and notes

11 11 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Structural Steel Shop drawings consist of detail drawings of all parts of the entire structure showing exactly how the parts are to be made These drawings show all dimensions necessary for fabrication, usually calculated to the nearest 1/16”

12 12 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Piece Marks A system is used to mark each piece that is separately handled This mark is called a piece mark and should be shown wherever the member appears on the drawings

18 18 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Connections Main members are joined together in the field to build a structure and most joints are welded connections to the main members Riveting is seldom used as a connection but you may find reference to riveted joints in original plans

19 19 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Connections AISC recommends certain standard connections for attaching beams You should know the strength of the various connections and use them only when they are sufficient

20 20 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Welding Welding is a common method for connecting steel members of buildings and bridges The fillet weld is the most common in structural steel fabrication

22 22 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. High-Strength Bolting for Structural Joints Two common types of high-strength steel bolts are ASTM A325 and A490

23 23 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Accuracy in Dimensions Incorrect dimensions on drawings will result in serious errors and misfits when members are assembled in the field Consider the effect of tolerance stacking on the fit of steel members

24 24 Technical Drawing 13 th Edition Giesecke, Mitchell, Spencer, Hill Dygdon, Novak, Lockhart © 2009 Pearson Education, Upper Saddle River, NJ 07458. All Rights Reserved. Concrete Construction Concrete is made by mixing sand, gravel, or other aggregates with Portland cement and water Reinforced concrete has embedded steel reinforcing bars In prestressed concrete, the steel is pretensioned before the superimposed load is applied
