NWSA Tower Structures and Inspection 2

Question 1

What are the three main types of telecommunications tower structures?

Accepted Answer

Self-supporting lattice, guyed, and monopole

Answer

Self-supporting lattice towers use a wide base for stability, guyed towers use wire supports, and monopoles are single tubular structures.

Question 2

What structural deficiency would require immediate work stoppage during a tower climb inspection?

Accepted Answer

Buckled or severely bent main structural members indicating potential structural compromise

Answer

Buckled or bent main structural members indicate the tower may have been overloaded and could be at risk of structural failure.

Question 3

How does ice loading affect tower structural integrity?

Accepted Answer

Ice adds substantial weight to all structural members and equipment, increases wind loading due to larger cross-section, and can cause member failure

Answer

Ice accumulation dramatically increases both dead weight and wind load on towers.

Question 4

What is the purpose of the TIA-222 standard in relation to telecommunications towers?

Accepted Answer

It establishes structural design, analysis, and inspection requirements for antenna supporting structures and antennas

Answer

TIA-222 is the primary industry standard governing structural design, loading criteria, and maintenance inspection requirements for telecommunications towers.

Question 5

During a tower inspection, what should be checked at the foundation level?

Accepted Answer

Concrete condition, exposed rebar, soil erosion, grout pad integrity, anchor bolt condition, and drainage

Answer

The foundation is what holds the tower up. Deterioration at the foundation affects the entire structure's stability.
