The aim is to use this assembled element for the region around the spot: two assembled elements, connected by a link, form the spot weld connection between two metal sheets.
Local stress analysis of a typical weld connection is carried out to obtain the hot-spot stresses in the region.
This paper focused on the ultimate strength of interface weld connection between gusset plate and frame elements when the brace is in tension.
Rupp and co-workers' method is suitable for application to large structural models because mesh refinement is not necessary for modeling the spot weld connection.
As a companion research, the frame action effects of non-moment braced frame and their influences on the cruciform BRB end section using full penetration groove weld connection to the gusset plate are discussed.
Butt weld connection is one of the most commonly used connection types in steel structures, and its post-fire mechanical property is crucial for the estimation of the residual mechanical capacity of steel structures after building fires.
