Working Group 4: Technical Expert Group on Masts and Towers


On decision by the Executive Council of the IASS in 2014 the name of the IASS Working Group 4 has been enlarged to: "WG4 Technical Expert Group on Masts and Towers". The idea by adopting Technical Expert Group is to emphasize that the main mission of the Group is to be an active group for technical experts interested in the analysis, design, construction and operation of masts and towers, while the name Working Group may suggest a group that is appointed to investigate and document some special issues for an association.

The overall mission of IASS WG4 is to encourage and synthesize presentations, reports and publications on projects, designs and research related to telecommunication towers and masts.

Current Objectives

The objectives of the Working Group are threefold:

  1. To act as the Global forum on mast and tower issues, whether they be commercial, aesthetic, theoretical or practical;

  2. To present and discuss papers on various topics related to masts and towers; and

  3. To provide design guidance for National and International Code drafting Committees.


In the 1960s, the development of broadcasting structures highlighted many design problems for tall lattice and spatial structures.  At a meeting of the IASS in 1969, a special working group (No. 4) was proposed to exchange ideas and experiences in order to form recommendations for design of guyed masts.  The resulting recommendations, published by the IASS in 1981, now form the basis of several international design codes and have considerably influenced the North American practice.

Recent Activities

The 26th Biennial Meeting of the Working Group for Masts and Towers in Paris, France was held successfully September 8th - 12th, 2013.  The meeting in Paris was arranged well by TDF, the biggest masts and tower owner in France.

Members of the WG authored 12 papers for a special double issue of the Journal of the IASS devoted to masts and towers.  The Special Issue is divided into two issues. Part 1 with 6 papers was published as Vol. 55 (2014) No.2 June, while Part 2 was published as Vol. 55 (2014) No. 3 September.

The 27th Biennial Meeting of the Working Group for Masts and Towers in Prague, Czech Republic was held successfully September 13th - 17th, 2015.

Current Membership

The Group comprises experts in this field including clients, designers, contractors and researchers who can address with authority the special problems related to masts and towers.  All meetings are held in an informal and confident spirit, and it is very important for the Group to maintain the informality and confidence built up over the years.  All members listed below are members of the IASS.  The Working Group welcomes additional members who have an interest and work with masts and towers.  Those interested should please contact the Chair or the Secretary of the Working Group.
