Contribution of Clearance Holes to Semi-rigid Effects of Bolted Joints

[摘要] This paper presents an analysis of semi-rigid effects of bolted joints occurring due to clearance holes and manufacturing tolerances at temporary fixing and the exploitation stages. The manufacturing requirements of SP 53-101-98 'Production and Quality Control of Steel Structures' and GOST 23118-2012 'Building Steel Structures. General Specifications' are used for calculations. Friction-grip joints with high-strength bolts are considered as well as joints with ordinary structural bolts. Different permissible assembling technologies are reviewed to account a non-linear behaviour of the joint at temporary fixing and during the operational stage. The recommendations were developed for the scheduling of mounting works which can provide convergence between the design of a whole building and the consequential calculations of mounting schemes.
