The calculation of jointswith the use of ordinary bolts for shear and crumpling under the existing national state building codes and European norms is considered.The formulas for the calculation of joints are given and their comparative analysis is carried out, as a result of which it has been established that, unlike national norms in Europeаn one joint safety factor is used, while national norms require the use of several coefficients;European norms, unlike national ones, are allowed to use joints in which the calculated shear plane crosses the part of the threaded bolt;the European norms in calculating the bearing capacity of the bolt on the shear is used the value of the ultimate tensile strength of the bolt, and national norms - the value of the design resistance of the bolt shear, which is, obviously, more reasonable than the consideration of the work of the bolt on the shear by introducing into the calculation formula of the additional coefficient;the calculation of the bearing capacity of the bolt to the shear in European norms is carried out without taking into account the coefficient of the working conditions of the connection and its value exceeds the value calculated according to national norms, indicating a significant understatement by national norms of the value of the design resistance of the shear bolt and the failure to take into account the bearing capacity of the bolt to the shear coefficient of working conditions of bolted connection;calculating the load bearing capacity of the bolt for crumpling in European norms gives a significant increase in value compared to national norms, although in the future, after the construction of the connection and correction of the corresponding coefficients bearing capacity significantly decreases, nevertheless in the final result is still much more than the similar value calculated according to national norms.In order to qualitatively evaluate an example of calculating the joint of elements according to different standards is done.
