Structural drawing

STRUCTURE AND MATERIAL Structural drawing consists of the preparation of design and construction drawings for buildings, bridges, domes, tanks, towers, and other civil structures. Most of our structures also have many interconnecting parts such as beams, girders and columns, that forms a structure. The materials most commonly used in construction are wood, glass, structural steel, aluminum, concrete (plain, reinforced, and pre-stressed), structural clay products, and stone masonry (plain and reinforced).

Joints and Connectors Typical Bolted Joints Metal Connectors for Timber Structures

22.4 STRUCTURE STEEL DRAFTING Structure steel drawings are ordinarily of two types: Engineering design drawings made in the design engineer’s office. Manufacturing (shop) drawings usually made in the office of steel fabricator. ME 210, Chapter 22, Week#13

Design Drawings Design drawings are primarily shown Overall dimension. Location of columns, beams, angles and other shapes. Listing the sizes of these members. Information about the cross section and connectors. Various necessary notes. ME 210, Chapter 22, Week#13

Design drawings Design drawings show the overall dimensions of the structure, such as the location of columns, beams, angles, and other structural shapes, and list the sizes of these members. Detail in the form of typical cross sections, special connections required, and various notes are also included. Typical Steel Floor Design Plan

W12 x 27 means Weight 27 lb per foot and width of the member is 12 inch. ME 210, Chapter 22, Week#13

Shop Drawings Shop Drawings consist of detail drawings of all parts of the entire structure, showing exactly how the parts are to be made. ME 210, Chapter 22, Week#13

Shop Drawings Fabrication, shop methods, and field construction methods must be fully understood by the detailer. Floor Beam Shop Drawing

WELDING The fillet weld is most common in structural steel fabrication. Use standard weld symbols to simplify making the shop drawings. 1/4 A ¼ inch leg length fillet weld

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

Piece Marks

Structural Steel Shapes Aluminum and magnesium shapes are also available but here only steel shapes. Structural steel is available in many standard shapes Available shapes are (made by rolling mills) Square, Flat, Round, Plate Angle, Channel, I-section, T-section, Most CAD programs have structural shapes symbol libraries available
