T plate connection is a type of non-moment-transferring connection (slip connection) that is bolted to the body of the profile and welded to the support. Bolt control, weld control and plate control are performed automatically according to the placement of the elements of the connection. Connection design with single plate is made automatically according to the Design, Calculation and Construction Principles of Steel Structures (ÇYTHYEDY) (GKT and YDKT) or AISC 360-16 (ASD and LRFD) regulations and the connection report is generated.
In the T plate connection calculation, distance control between bolts, horizontal and vertical edge distance control, weld thickness control, mounting stability controls are made as geometry control. As a strength control, checks are made for shear in the beam bolt, crushing in the beam and plate bolt holes, plate shear yielding, beam and plate shear failure, block slip in the plate, plate bending buckling, plate bending yield, support welding strength.
