CEN/TC 53/WG 5 - Methods of assessment of load bearing towers

This European Standard describes methods for establishing structural data for stiffness and resistance by calculation supported by tests for load bearing towers made of prefabricated components of steel or aluminium alloy. The vertical load capacity is established, both with or without horizontal loads and with the top  restrained or free.
This European Standard specifies two methods of analysis, by  first order theory, or by  second order theory.
NOTE   For definitions and requirements relating to structures and materials of the structure, specifications and loads, see EN 12812.
The European Standard is not intended for towers constructed with tubes and couplers: it is expected that they will be designed in accordance with EN 12812.
