The Conference Center of Badajoz, designed by architects José Selgas and Lucia Cano, is an outstanding example of an elegant public building integrated into a consolidated urban area.
The main building has a circular layout and is surrounded by an external façade – like a big fence- made of GFRP profiles.
Apart of the excellent mechanical and physical properties of GFRP profiles (durability, high specific strength and low weight) the architects wanted to use a translucent material.
This structure is a helix, 246 ft (75 m) in diameter with a maximum high of 45 ft (14 m) using more than 7 mi (12 km) of GFRP pultruded translucent profiles. Profiles should have an external elliptic cross-section and they define the helix which is
supported by very slender vertical galvanized steel columns of only 4’’ (117 mm) in diameter.
