4 bolt unsitffened end plate connection is a moment-resisting joint (rigid joint) that is connected to the columns' flange to the beams. Bolt control, weld control, plate control and joint application limits control are performed automatically according to the placement of the elements of the joint. 4 bolt unstiffened end plate connection is made automatically according to the Design, Calculation and Construction Principles of Steel Structures (ÇYTHYEDY) or AISC 360-16 regulations and the connection report is generated. Connection detail application limits are checked according to TBDY Table 9B.1.

In the calculation of the conecction, the horizontal and vertical bolt distances, end plate weld thickness, continuity plate weld thickness and application limits are checked under geometry control. In strength checks, bolt diameter, end plate thickness, end plate shear yield, end plate shear failure, etc. are checked and reported.
