Abstract—Composite trusses, a very efficient alternative to
overcome large spans for civil engineering, are usually
constructed with corner sections, and in many cases, have a
central Vierendeel panel, which the main objective is to enable
the passage of pipes, unhampered in frames with the presence of
diagonals. This work aims to study the feasibility and ultimate
limit state to extend Vierendeel panels across the central third
of the structure and replace the corner for hollow sections. The
fundamental points that supported the theoretical calculation
and, especially, how the numerical modeling of the composite
Vierendeel-truss was performed, were indicated. The results
showed that the regions of the structure with higher stress,
determined by finite element method via software Ansys, were
the same identified by the analytical calculation and
bi-dimensional elastic modeling as acting the highest internal
forces, thus validating the methodology of proposed calculation.
