All About EN-1993-3-1
EN-1993-3-1 is a structural Eurocode, used in designing the steel structures of towers and masts. Dist Eng. Use this Eurocode in creating the towers and poles. Let us talk about structural Eurocodes first.
Structural Eurocodes
Each Eurocode includes several parts separately published. Every section comprises a wide range of documents, legislative annexes, and informative annexes, of which the national significance is determined.
In the beginning, the European Standard Committee (CEN) publishes the entire text for every section of the Eurocode in three language names, and national standard bodies that translate the text into other languages but not make any technical changes. Consequently, the information is the same as contained in this text for every European country.
Each national standard body provides an original cover and foreword to the Eurocode text, published in this country with a national prefix designation, e.g., BSI updates its EN 1990 as BS EN 1990. A regional annex or a national annex may be published independently, and the text is published accordingly.
The sections of the Eurocode have two different types of definitions,’ Principles.’ Firstly, compliance must be followed; secondly, rules that comply with the Principles can apply alternative conception rules. The first must be pursued.
It was not to repeat the principles and rules of application that the underlying philosophy used to draft Eurocodes was to. The basis of design for BS EN 1990, therefore, applies regardless of construction material or form.
UK designers should be mindful that Eurocodes uses obscure terms and notation resulting from the desire to be consistent across Europe.

Before talking about this, we have to know about Eurocode 3, that is the steel structure design
Eurocode 3: The steel structural designing
What does it contain?
The application of BS EN 1993 is broader than most other Eurocodes, because of the complexity of steel structures. It contains EN-1993-3-1 and EN 1993-3-2. Eurocode also covers boiled and welded joints and slim construction in the future.
Compared to current UK standards, the real difference is that the Eurocode introduces new methodologies. For instance, explaining the design of semi-stiff seals in houses, and further include methods for the design of cold-formed works of steel. Shell and stack building, sheet piling and silos rules are new, and for the first time, restrictions on stainless steel are in effect.
BS EN 1993 includes standard regulations, fireworks buildings, bridges, constructions and reservoirs, silos, pipes, cranes, towers and mast systems, etc.
The main aim of Eurocodes is to incorporate the latest knowledge in this field and to the NDPs for Eurocodes to harmonize more effectively. In fact, the revisions reflect the practical experience gained from existing codes. The stabilization amendments to Eurocodes, however, are subject to the CEN / TC 250 regulation. The steel structure Eurocode consists of several parts including
EN 1993-3-1 for ‘Masts and Towers’
EN 1993-3-2 for ‘Chimneys.’
Which means EN 1993‐3 includes the ‘Poles, Towers, and Chimneys’.
The design basis for such antenna supporting structures is sometimes different and often contradictory, and the overall structural configuration may have a dramatic effect on the system load. The loads are mostly wind and ice meteorological, and a mix of these. Always consider the dynamic nature of wind, as masts and towers are more or less susceptible to dynamic loads.
EN 1993-3 contains EN 1993-3-1, used as the Eurocode for designing the towers and masts. Masts and towers analysis and design require specialist knowledge and expertise, especially when it comes to poles. “A guyed mast is one of the most complicated structures an engineer can face,” according to experts who think the many collapses that have occurred over the years underline the unique problems associated with these structures.
