INITIAL DEFORMATIONS OF BOLTED JOINTS IN METAL STRUCTURES

Abstract

The congruence between conventional calculation schemes and theoretical behaviour of metal
structures considering manufacturing tolerances is examined. Tolerances are accepted by building
codes for fabrication and erection. Conditions are found under which the calculation schemes probably
do not reflect the real work of structures. In addition, the effect of mounting technology on carrying
capacity (against sliping and bolt shearing) of temporary connections is considered, as well as
connections at the operational stage. Conclusions are drawn that initial deformations of bearingbolted
connections of metal structures should be taken into account when comparing the variants of
mounting technology, as well as load-bearing capacity reduction in friction-grip connections.
