The acting forces on the T-Stub bolts are investigated in this research taking into consideration the prying action associated with the variations of T-Stub geometry and bolt positions. apuseni natural park romaniaWebb1 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. apuseni winter

"Webb29 nov. 2015 · This ad-ditional bolt tension is the prying force, q, shown in Figure 2. Designing for prying action involves checking the limit states of bending of the fitting and tension rupture of the bolts. The two limit states are interdependentfor a given load, an increase in flange thickness leads to a lower prying force on the bolt. " - Prying action on bolts

Therefore, neglecting prying action could lead to unsafe design. One can avoid designing with prying action by using thick flanges [ 4, 5 ].

Webbby designing the connecting element and bolted joint for the actual effects of prying action with q greater than zero.” One should view prying as a way to increase the strength of a con-nection.
