The joining plates connection is a moment transmitting connection formed by connecting the end plates welded to two beams with bolts. Bolt control, welding control, plate control are made automatically according to the placement of the elements of the connection. The connection design of the joining plates 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 created.
In the calculation of the joining plates connection, the distance between the bolts, the horizontal and vertical edge distance of the bolts and the weld thickness are checked under geometry control. In the strength control, tension in the support bolts, thickness of the end plate, shear yield of the end plate, shear failure of the end plate, slip on the support bolts, crushing of the bolt hole in the end plate and weld strength are checked.
