Design Works on Carcassing the Circus Big Top in the Block “A” while Reconstructing Penza Circus

The project designers describe their experiment on carcassing the big top of the main building (Block A), the largest in Europe after the reconstruction of Penza circus. Due to the difficult conditions at a construction site, it was necessary to find an acceptable method to enlarge trusses of the big top, also to determine a method and sequence of erection of completed trusses with optimal application of erection crane's weight and high-altitude characteristics. Four options were considered for pre-assembly works of parts suitable for transportation of trusses. Assembly line technique of trusses was developed based on an agreed upon with the executive version. A small area was dedicated for this purpose. Erection and dismantling method of the big top was developed. The project is accepted for production.
