Aspects on designing the truss elements welded joints

Abstract

The structural advantages of tubular steel elements have become increasingly obvious in recent decades because of research and experience in construction. Worldwide, these elements are frequently used especially at large span structures. In the past, the cheap permitted the manufacturing of the truss beams made of angle type elements joint in nodes with gussets. With 21st century in our country appeared new structural solutions for lattice subassemblies, one of the solutions being the use of RHS (Rectangular Hollow Section) elements joined with welding directly onto the chords. The present paper propose the applying of the component method [8] to a common joint (truss beam), calibrating a finite element model and determine the improvements possibilities.
