Welded Flange Plate Connection Design
- Kemalcan Struja (Unlicensed)
- Zeynep Aladağ
The Welded Flange Plate Connection is formed with butt welded welded head plates with cotton penetration to the column head and corner welded to the beam head. Body plate bolt control, welding control, plate control and connection application limits control are made automatically according to the placement of the elements of the connection. Welded Flange Plate 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 calculation of the Welded Flange Plate Connection, the header plate and slip plate weld thickness, slip plate column head weld thickness, continuity plate - column head and body weld thickness are checked under geometry control. Head plate weld strength, header plate tensile failure, block slip at beam head, pressure plate leakage, slip plate weld strength, shear plate beam body strength, body plate shear failure, body plate bending yield, column panel region slippage are checked.
