Detailing and Construction of the Pantadome Roof Structure for a Bullring in Xàtiva (Spain)
This paper describes the detailing and construction of a roof structure for a bullring in Xátiva (Spain). The roof has been built by means of a new version of the Pantadome system. The roof dome is spherical shaped with a 42 m diameter central opening and an exterior diameter of 101,6 m. It is supported on 44 columns distributed along a 86,4 m diameter circumference. The structural system is formed by radial truss lattices pinned to the columns and to the inner ring and supported by the action of an outer tension ring, radial tension members and tension (upper chord) and compression (lower chord) in the inner ring. The structure was built near the ground and lifted by shortening 44 radial strands with jacks attached to the inner ring. Strand forces have been transferred to permanent tension members at the end of the process. The kinematics of the deployment has been analyzed. Forces in the jacks have been obtained theoretically from the kinematics and compared with the measured values. Special details, developed for the attachment of the jacks and the force transfer are described. The development of the lifting process together with the results of the geometrical survey show that the new erection system allowed the construction of the dome in a quick and safe way.
