Structural Analysis Work Instruction:

Key:

V=Vertical D=Diagonal P=Pipe/Tube OD=Outside Diameter #=Number of pieces H=Horizontal L=Angle S=Solid

• Guy System Configuration Bottom:

o Distance(s) from center of tower to top of anchor (fan plate, or eyelet).

o Turnbuckle size, bolt or fattener size connecting the turnbuckle to the anchor plate, saddle clamp size and number, guy anchor size and type.

• Guy System Configuration Top:

o Guy pull-off elevation(s).

o Turnbuckle size (if applicable), bolt or fattener size connecting the turnbuckle or guy wire to the tower, saddle clamp size and number, mounting bracket size and hardware size/configuration.

Guy System Data Collection Example:

USFS TOWER STRUCTURAL ANALYSIS FORM 7

• Structural analysis data collection:

o Face width is to be collected at the bottom of each section and at the top of the overall structure (not to include mast sections).

o If the top section of the tower converges to a single point extending above the tower it should be identified as a “mast” with dimensions provide in the face width row.

o Leg thickness should be collected on each leg of the tower at each section and entered as an average for each section.

o Towers with members designed to be climbed like a ladder should not be considered a mounted ladder.

o Tower panels are to be identified by each diagonal or set of diagonals. Example in a Z brace configuration presenting 7 diagonals in a section the tower has 7 panels in that section.

o (#xbolt) is asking the number of bolts and bolt size at a single connection point. Example a tower flange has 4 bolts, and each bolt is

5/8” in size (4x5/8”).

o If a tower horizontal is between gusset plates the length measurement is required.

o Tower section greater than 50ft shall be divided in 2 sections with the sections being separated at the top of the most centrally located horizontal brace.

Partial braces are to be regarded as a “Step”. Measure top off brace to top of brace.

Structural Analysis Data Collection Example:

USFS TOWER STRUCTURAL ANALYSIS FORM 8

• Equipment Inventory and Data Collection:

o Measure the elevation mounted to the first mounting point on the tower.

o Offset from the tower structure should be measured from outside of member attachment point to outside of equipment mount.

o Transmission line size, number, and spacing between lines (if applicable) should be identified separate from a mounted feed line ladder.

o Dimensional data for equipment should be entered (length x width x depth), with extension pipes like on dipoles measured as well

(diameter x length).
