The Reinforced Spun Concrete Poles under Physical Salt ...

The present paper focused on the investigation of the effectiveness of using various chemical admixtures and their effect on the strength and deformability of the reinforced spun concrete members—the supporting poles of the overhead power transmission lines—under the unfavorable long-term combined action of the aggressive salt-saturated groundwater and the temperature changes.

Strength and deflection behavior of spun concrete poles ...

Prestressed spun concrete poles are used primarily for supporting electric power transmission lines and distribution and for area lighting. In many applications they are placed directly in brackish water or saltwater, resulting in deterioration of the concrete pole due to steel corrosion. A new type of reinforcement that can provide the desired structural characteristics and at the same time ...

Torsion tests on spun-cast prestressed concrete poles

This paper focuses on the effect of the transverse reinforcement—its amount, spacing, and direction—on torsional strength in an effort to simplify the governing codes and provide general information on the behavior of spun-cast prestressed concrete poles under pure tor- sion. The rationale behind the typical code values for spacing and direction of the transverse reinforcement is not apparent.
