LOAD TESTING OF PRESTRESSED CONCRETE TRANSMISSION POLE AND ITS CONCRETE FOOTING

Full-scale load tests on a centrifugally spun, prestressed concrete pole installed in a reinforced concrete footing indicated that this structure can be used for transmission lines if some dimensional changes are made to increase the torsional capacity of the pole to withstand broken-conductor loading conditions. The reuslts also showed that the strength and behaviour of the pole can be predicted analytically if the actual dimensions and properties of the materials are known. Strains in the reinforced concrete footing were very low and, in this case, indicated no need for reinforcing steel to resist stresses due to exterior loading. Where reinforcement is required for the control of cracks due to temperature and shrinkage, it need be included only in the upper part of the footing. /Author/
