Webb1 maj 2024 · In such connections prying action phenomenon may take place. Prying action effect on the bolts has been studied before but the location of the prying action forces … Webb1 maj 2024 · Afterwards, many scholars [9], [10], [11] studied on the behavior of prying action for extended end-plate connection and proposed improved design of the connection allowing for prying effects. However, the academic study pays relatively less attention to prying action in the flange connection, which has a great influence on the bolt force.
