Lonestar Prestress Mfg., Inc. concrete poles weredeveloped to meet the expanding need of a supportingstructure for; street, highway and area lighting, athleticlighting, signs, overhead power distribution and powertransmission as well as power substations and trafficsignals.

50+ Year Service LifeLonestar Prestressed Concrete Poles are safe for the envi-ronment, require no maintenance and have a life of Fifty(50) or more years.

High QualityEvery Lonestar Pole is an engineered product designedfor each specific application and produced under rigid stan-dards of quality.

No MaintenanceLonestar Prestressed Concrete Poles require no painting,will not rust, are impervious to sunlight (ultravioletradiation), chemicals (fertilizers, oils, etc.), animals andinsects (woodpeckers, termites, etc.) and do not requiregroundline treating.

High StrengthLonestar Prestressed Concrete Poles are classified by theirultimate capacity to sustain a horizontal load applied at apoint two feet below the tip. Lonestar’s concrete is a specialhigh-strength mix design put into compression byprestressed ASTM 416 high-strength steel strands.

Engineering Standards: Concrete vs. WoodBecause wood deteriorates over time, The American National Standards Institute, (ANSI) andthe National Electric Safety Code, (NESC), require wood poles to have an initial load factor60% greater than equivalent concrete poles.

When establishing WPE criteria, the difference between the two structural systems (materials) must be considered:

Wood: NESC requires an overload capacity factor (OCF) of 4.0

Wood poles are composed of a naturally grown, biological material,which exhibits inconsistent material properties throughout the length ofthe pole. These inconsistencies, which have a direct impact on strength,are knots, checks, shakes and splits.

Wood poles are susceptible to rot and decay over the design life of thestructure. The wood pole has less strength at the end of its service lifethan when it was originally placed in service.

Wood poles are susceptible to insect and animal attack. The effects oftermite and woodpecker attack can significantly decrease the loadcarrying capacity of the wood pole well before the end of the anticipatedservice life.

Prestressed Concrete: NESC overload capacity factor (OCF) of 2.5

Prestressed concrete poles are fabricated from engineered materials.The prestressed concrete poles have consistent material propertiesthroughout their length.

Prestressed concrete poles are not susceptible to rot and decay. Theprestressed concrete pole has the same strength throughout its servicelife.

Prestressed concrete poles are not susceptible to insect and animalattack.

Wood pole classes are determined by the strength required at the groundlineto resist a transverse ultimate load placed 2 ft. below the tip of the pole. Eachlength of pole within a pole class can resist the same load placed 2 ft. fromthe top.

When designing pole structures for transverse wind loading, the NESCrequires an overload capacity factor (OCF) of 4.0 for wood poles and 2.5 forconcrete poles when determining ultimate loads (Grade B construction). Dueto the above mentioned differences in the structural systems, the NESCrequires the wood pole to have a strength that is 60% higher than theprestressed concrete pole. Therefore, the prestressed concrete pole can bedesigned for a load that is 62.5% (2.5/4.0) of the wood pole load and attainthe same strength for the specific pole class throughout the life of thestructure.

WOOD POLE EQUIVALENCY

Traditionally, designers have specified wood poles for use as utility structures according to the pole class system set forth in theAmerican National Standards Institute’s specification ANSI 05.1, Specifications and Dimensions for Wood Poles. In order to remainconsistent with the pole class system for utility structures, we have developed a wood pole equivalency (WPE) system for ourprestressed concrete poles. Our WPE system is based on criteria contained in ANSI 05.1 and the National Electric Safety Code(NESC), ANSI C2.

Prestressed Concrete Utility PolesU-4



Prestressed Concrete Utility PolesU-5

WOOD POLE EQUIVALENCY EXPLAINEDIn order to simplify our WPE system we choose to use the ultimate pole top load that is two loadclasses lower than the wood pole. For example, ANSI O5.1 lists an ultimate pole top load of 4,500lbs. for a Class 1 wood pole. Our concrete Class 1-C pole is designed for a 3000 lbs. (Class 3 woodpole load) ultimate pole top load. The ratio of the loads is 3000/4500=0.666, which is in excess of2.5/4.0=0.625 using NESC overload capacity factors for transverse wind.

5-C 1,200 0.632

The above wood pole equivalency system is based on the following assumption:

1. Transverse wind is the controlling design load.2. The load acts perpendicular to the face of the pole.

When design configurations involve the use of angle poles and dead end poles where other thantransverse winds control the design, our technical staff should be consulted.

Example:

WOOD POLE EQUIVALENCY EXAMPLEExample:

The following example is for the purpose of demonstrating our WPE system only. In actual designcases, loads other than transverse wind may control and must be investigated.

Assumptions:- Tangent pole.- Equal conductor spans on both sides of poles.- Transverse wind creates controlling load case for selection of pole.- For simplicity, the wind pressure on the pole is neglected in this example but should be added tothe ground line moment for actual design.- NESC overload capacity factors: 4.0 for wood poles

2.5 for prestressed concrete poles- Wind load on conductors produce a resultant load of 1125 lbs., 2 ft. down from the top of thepole.

Pu = 4.0(1125 lbs.) = 4500 lbs.For ANSI Class 1 wood pole:Pmax = 4500 lbs.

Pu = 2.5(1125 lbs.) = 2813 lbs.For ANSI Class 1-C prestressed concretepole:Pmax = 3000 lbs. (Class 3 wood pole load)

The concrete Class 1-C pole is more than adequate for the transverse wind load. Note the max loadof 3000 lbs. for the prestressed concrete pole is the same as for a Class 3 ANSI wood pole.

GENERAL INFORMATION

1. Different colors, finishes and exposed aggregates are available upon request.

2. All corners are chamfered.

3. 7,000 PSI concrete is standard; higher strengths are available if required.

4. STRENGTH: In most cases a higher ground line moment and a higherbreaking strength and EPA can be attained without going to a larger pole.

5. EFFECTIVE PROJECTED AREA (EPA): Lonestar Prestress Mfg.concrete poles and mounting arms have been designed in accordance withaccepted engineering practices to be structurally capable of withstandingwind loads and velocity pressure up to 140 MPH (gust speed) per ASCE 7-02. Poles to meet higher wind loads are available.

6. HOLES: Holes are precast to meet your specifications and requirementsfor mounting attachments, most any desired arrangement can be provided.The prestressing cables are located so that field drilling is permitted on thecenterline of either axis. Field drilling can be accomplished with the use ofrotary hammer drills.

7. INSTALLATION: Lonestar Prestress Mfg. concrete poles are designed forsetting directly into the ground, without the use of precast foundations, similarto the setting of wood poles. After the hole is drilled, the pole is set andplumbed, the earth is then backfilled and tamped. The depth is dependenton the nature of the soil and the anticipated load. Where it is impossible toembed the poles in the ground, such as on bridges or overpasses, a boltdownbase plate is available.

8. To specify a base plate for base mounted poles add the suffix BP to catalognumbers. Customer to supply the bolt circle drawings or template.
