# Bolted Flange Plate Connection Design

Bolted Flange Plate Connection is formed with header plates welded to the column head and bolted to the beam head. Bolt control, weld control, plate control and joint application limits control are performed automatically according to the placement of the elements of the joint. Head Plate Bolt Joint design is made automatically according to the Design, Calculation and Construction Principles of Steel Structures (ÇYTHYEDY) or AISC 360-16 regulations and a joint report is created. Joint detail application limits are checked according to TBDY Table 9B.2.

In the calculation of Head Plate Bolt Joint, horizontal and vertical bolt distances, butt plate weld thickness, continuity plate weld thickness and application limits are checked under geometry control. Bolt diameter in strength control, slip in cap and body bolts, crush in cap and body bolt hole, crush in beam cap bolt hole, head plate tensile yield and tensile failure, block slip in head plate and beam head, beam and body plate shear failure, block in body plate slip, body plate bending yield, slip plate column head weld strength, column panel region slip and slip region thickness control are performed.
