Strength calculation of prestressed bolted connections analysis using available computational software and fem method

This paper deals with analytical calculations and FEM strength analysis of prestressed bolted connections as well as their experimental verification. Design engineers use in the strength calculation technical recommendation of fasteners sellers and fasteners manufacturers when designing of bolted joints. In industrial practice, it is now very often required to calculate the prestressed bolted connections according to the standard VDI2230. [1] The calculation is usually performed using KissSoft or MITCalc programs on a personal computer.
