Structural Drawings

•Assembly Drawing Skeleton assembly drawing showing the relationship of variousparts to be fitted together in the finished structure

• Engineering Design Drawing

Plan view (top view), Elevation view (front view), Bottom section (bottom view) shows overall dimensions, location and size of columns, beams, angles, ….. , Detail of connections, typical cross sections, various notes.

• Manufacturing (shop or working) Drawing

Detail drawing of all parts of the structure, all dimensions to the nearest 1/16 “, location of all holes for connections, detail of the connection parts, required sizes of all materials

Dimensioning and scale

Dimensioning examples: ¼, 10, 1’- 0, 2’- 3¼ , 4’- 0¾,

Incorrect dimensioning: 0¼, 2’-03¼

Scale: ¾” = 1’- 0 or 1” = 1’- 0

Trusses – A truss is a configuration of structural elements (triangle) that adds strength to a support, bridges and roofs.

Truss members carry tension or compression loads, no bending.
