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.Index Terms-Composite truss, hollow structure, vierendeel panel.

“…It resists in conjunction with the performance of the top chord and with a composite action between the slab and the top chord. This is called the group resistance, described in the works of Lawson (Lawson, 1987) and Lawson and Hicks (Lawson & Hicks, 2011).…”

“…The interaction between bending and axial force is complex. However, Lawson and Hicks (Lawson & Hicks, 2011) evaluated in the composite phase that when the section is compact, the reduced moments, M Rd,red , can be determined from the plastic resistant bending moment, M Rd,pl , according to Equation 4, where N Sd and N Rd are respectively, the design normal force and design resistance to normal force on the chords.…”

ResumoO objetivo desse trabalho foi avaliar, através de cálculo analítico e modelagens elástica bidimensional e plástica tridimensional, a capacidade resistente e o modo de ruptura de treliças tubulares mistas biapoiadas com 15 metros de vão, variando-se o número de painéis Vierendeel centrais. O estudo apontou a proporção vão/3 -vão/3 -vão/3 como a ideal para a relação entre trechos treliçado -Vierendeel -treliçado, pois, ao se aumentar a proporção do trecho central, ocupado pelos painéis Vierendeel, os novos sistemas perdem muita rigidez, passando a não suportar mais a carga estipulada em projeto. Além disso, podem passar a apresentar deslocamentos verticais excessivos e resistência às forças cortantes externas atuantes sobre os painéis insuficiente. Palavras-chave:Treliça mista, painel Vierendeel, estrutura tubular. Abstract The aim of this study was to evaluate through analytical calculation, two-dimensional elastic modeling, and three-dimensional plastic modeling, the bearing capacity and failure modes of composite hollow trusses bi-supported with

2An innovative form of slim floor beams is proposed in which the shear connection is formed by combining the concrete passing through the web openings with a steel tie-bar element. A numerical study was conducted to evaluate the flexural behaviour of these composite shallow cellular beams. The force transferring mechanism, load-bearing capacity and failure patterns of the shear connections were also evaluated. Two different configurations of shear connection were designed and a parametric study was carried out to determine the parameters likely to influence their performance. The findings were incorporated with bending and push-out test results to develop design methods for this form of shear connection. A tentative design procedure for the composite shallow cellular beams is proposed. Notation
