Explanatory notes

Specifies precast reinforced or prestressed concrete lattice towers, masts or columns ('masts', for short) made of spun concrete or vibrated concrete, used to support overhead power and telecommunication lines ('overhead lines', for short) or as catenary supports, lighting columns, public address systems, aerial masts, etc., and covers ancillary items (e.g. bracings). Makes more detailed provisions than EN 40 Part 9, especially with respect to design calculations.
