THIS DOCUMENT FOR INFORMATION ONLY, NOT FOR CONSTRUCTION
1. OBJECTIVE/PURPOSE STATEMENT
The purpose of the structural analysis report is to:
Analyze and determine the adequacy of the existing tower to support the existing loading conditions
Develop a proposal to reinforce the tower as required to meet the current TIA-222-G code standards and have a tower rating of 75%
2. STUDY SCOPE
The scope is limited to developing a tower model using tnxTower software and to provide a cost estimate for retrofitting the tower as required to ensure all members are below the allowable limits. The model shall use field gather information, available previous structural analysis report and previous mapping report provided by FAA.
At the time of this report no foundation or geotechnical data has been collected and is pending.
As a result, the foundation cannot currently be analyzed. This report addresses the tower.
3. APPLICABLE CODES, STANDARDS AND REFERENCES
American Society of Civil Engineers (ASCE) 7-10 International Building Code (IBC) 2015 TIA-222-G Structural Standard for Antenna Supporting Structures and Antennas with
Addendums 1, 2, 3, and 4.
4. BASIS OF DESIGN
The structural geometry is based on government furnished information found in appendix B (GFI) and site visit performed by Parsons. The tower is a 160 ft. self-support tower with a triangular cross section and stacked in 20 ft. sections. The legs are pipe members. The diagonal and horizontal bracing are angle members. The tower tapers from 23ft. at the base to 9.75 ft. at 140ft. From 140 ft to 160ft the tower is vertical with a face width of 9.75 ft.
Structural:
Tower Design Criteria:
Wind (TIA-222-G) Tower is located in El Centro, Texas Basic wind speed of 85 mph (3-second gust) Structure Class III Exposure Category C Topographic Category 3 Crest Height 450 ft Deflections calculated using a wind speed of 60 mph
Pressures are calculated at each section
Wind (ASCE 7-10)
Ultimate wind speed of 115 mph Risk Category III Exposure Category C
Seismic Ss = 0.693 Ss is less than 1.0 and therefore seismic does not need to be evaluated.
Ice Loads Nominal ice thickness of 0.0 in Ice thickness is considered to increase with height Ice density of 56 pcf A wind speed of 30 mph (TIA-222-G) is used in combination with ice
Steel Design Criteria:
Materials: Steel Legs: Fy = 50 ksi Steel Angles: Fy = 36 ksi Bolts for connections: A325N Design Procedures: Shall conform to TIA-222-G with Addendums 1 to 4, and
AISC Manual of Steel Construction 14th edition
5. CRITERIA, ASSUMPTIONS, AND INPUT
Assumptions:
The structure has been properly installed and maintained The diagonal and horizontal members are bolted to the tower leg and considered pinned Foundation depth, reinforcement size, spacing and clear cover are assumed to be adequate for the existing tower and the retrofit design Foundation bearing capacity is assumed to be adequate in the absence of a geotechnical investigation or report. For a rigorous structural analysis both geotechnical and foundation data will be required.
There are no structural deficiencies All existing loading including antennas feedlines and other discrete appurtenances are assumed to remain in place as observed in the site visit
A three dimensional finite element model of the tower was created and analyzed using the tnxTower version 7.0.7.0 by Tower Numerics Inc. tnxTower is a general purpose modeling analysis and design program created specifically for communication towers using the TIA-222-G code standard. It has the ability to design three of four sided guyed and free standing towers.
6. CALCULATIONS METHODS, MODELS AND COMPUTATION
7.1 Existing Conditions
Observed changes in the loading between the government furnished information and the recent site visit are as follows:
Loading which has been removed o Hollow structural steel member at 87’ o Pipe mount at 25’
Loading which has been added o 12” microwave dish at 31’
With the current loading the tower rating is 202.6%.
Member which have a tower rating greater than 75% include the following:
Legs Members o Section T7 (126.5%)
Diagonal Members o Section T4 (79.6%) o Section T5 (105.6%) o Section T6 (202.6%) o Section T7 (162.4%) o Section T8 (153.2%)
7.2 Proposed Modifications
The tower rating can be brought to the targeted 75% by installing the following modifications
Leg Modifications o Installed Angle Stiffener to Pipe
Section T7 Diagonal Modifications o Installed Angle Stiffener to Angle Section T4 Section T5 Section T6 o Remove and Replace Angles Section T7 Section T8
7. RESULTS
It should be noted that direct access to the leg in section T7 (20’ – 40’ AGL) will be required to install stiffing steel along the length of the leg. The leg modification which is currently present on the tower in section T8 (0’ – 20’ AGL) will need to be continued up into T7. The existing loading in that section needs to be removed temporarily as the modification is installed. After the leg modification is installed the loading can be placed back on the tower leg.
Fig 1. Leg Modification for Section T7
7.3 Cost Estimate
Below is the estimated cost to install the proposed modification to the tower in order to bring the tower rating to the targeted 75%. This is a rough order of magnitude estimate.

The structural analysis has determined the following:
The existing rating is 202.6% for the tower.
The tower can be reinforced by installing additional stiffeners to the legs and additional stiffeners to or replacing the diagonals. This will bring the tower rating to the targeted 75%.
The estimated cost for the tower modification is $88,080.
The foundation has not been analyzed. The acquisition of foundation and geotechnical data is currently pending. Remediation to the foundation may be required to bring the rating below 75%.
Recommendations can be made once the foundation investigation is completed.

Tower Input Data
The main tower is a 3x free standing tower with an overall height of 160.00 ft above the ground line.
The base of the tower is set at an elevation of 0.00 ft above the ground line.
The face width of the tower is 9.75 ft at the top and 23.00 ft at the base.
This tower is designed using the TIA-222-G standard.
The following design criteria apply:
Tower is located in Imperial County, California.
ASCE 7-10 Wind Data is used.
Basic wind speed of 115 mph.
Risk Category III and IV.
Exposure Category C.
Topographic Category 3.
Crest Height 450.00 ft.
Deflections calculated using a wind speed of 60 mph.
Pressures are calculated at each section.
Stress ratio used in tower member design is 1.
Local bending stresses due to climbing loads, feed line supports, and appurtenance mounts are not considered.
