The brace corner connection is formed by bolting and welding the steel brace member to the column, beam or column-to-beam connection. Bolt control, weld control, plate control and connection application limits control are performed automatically according to the placement of the elements of the connection. Brace corner connection design is made automatically according to the Design, Calculation and Construction Principles of Steel Structures (ÇYTHYEDY) or AISC 360-16 regulations and a connection report is created.

In the brace corner connection calculation, horizontal and vertical bolt distances, end plate weld thickness, continuity plate weld thickness and application limits are checked under geometry control. In strength control, cross bolt slip, plate bolt hole crushing, ski control, Whitmore section buckling, plate pressure leakage are checked.
