Installation technology of civil buildings' large-span structures on the example of erection of multifunctional sports complex truss
Incoming article date: 18.10.2021The article provides the information about the erection procedure of a 50.3 m span truss of a multifunctional sports complex in Nefteyugansk, Russia. The expediency of the considered large-span structure in finished form was substantiated by authors. The advantages and disadvantages of the options for choosing the erection procedure were analyzed in detail. Both types of finished truss erection were simulated in Autodesk Revit software: erection with one crawler crane and with two truck mobile cranes. The advantages and disadvantages of these two methods were observed. Erection process with two truck mobile cranes Liebherr LTM 1160-3.1 does not require complicated motions on the construction site, however it is imposiible with intalled beams between coloumns. For erection process with one crawler crane Liebherr LTM HS 855 HD temporary roads is not necessary, but this crane needs special transport for delivery on site.
