The developed structural design of the steel structure corresponds to the specified external architectural form and functional volume of the roof part of the recreational and spa complex, which are a combination of a cylindrical vault and a segmental part of a spherical dome.
The requirement to design a combination of movable and fixed roof structure and the need to bridge a large support distance necessitated the use of a unique structural solution
The design for the steel roof structure over the recreational and spa complex was prepared in accordance with European building construction norms and in compliance with current Bulgarian norms and standards.
