Abstract

Electric power transmission needs huge amount of investment. The electric industry requested further improvement in strength of steel angles for transmission towers as an effective means of the cost reduction. This is the report of the final results obtained by the committee which was formed it accordance with this requirement in April 1988. The successful outcome will be approved b3 Japan Society of Steel Construction and become one of its standards in September 1999. The newly developed angles will become in practical use in the near future after several structura. tests.
