1. EXPERIMENTAL INVESTIGATION ON CONCRETE FILLED STEEL TUBULAR COLUMN TO FOUNDATION CONNECTIONS SUBJECTED TO COMBINED AXIAL AND LATERAL CYCLIC LOADING
Abstract This study focuses on performance of CFT column to foundation connections subjected to combined axial and lateral cyclic loading. Experimental investigations were carried out on five specimens with exposed column base and embedded column base connections. The parameters considered were number of stiffeners and embedment depth of CFT column. The forc

2. Influence of shear lag coefficienton circular hollow sections with bolted sleeve connections
Abstract The circular hollow sections (CHS) are being widely employed in steel structures around the world, increasing the development of new researches. This article proposes an innovative connection model for circular hollow sections that facilitates and reduces the assembly cost of hollow section structures. The proposed connection is a tube sleeve, used

3. Temperature field of concrete-filled steel tubular columns in fire
Abstract The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil const

4. Estudo de ligações pinadas com chapa de topo para aplicações em estruturas metálicas treliçadas tubulares planas / Study of pinned gusset plate connections for application in uniplanar trusses with circular hollow sections
Este trabalho apresenta o desenvolvimento de uma concepção estrutural para ligações de treliças metálicas tubulares de seção circular com chapa de topo através de um estudo teórico-experimental. Nesta concepção as extremidades das diagonais são superpostas e unidas por um único parafuso fazendo com que a ligação seja pinada. A colocação da

5. Análise teórica e experimental de ligações em aço entre pilar tubular de seção circular e viga de seção I / Theoretical and experimental analysis of steel connections between circular hollow section column and I section beam
O atrativo estético proporcionado pela forma arredondada é o fator que na maioria das vezes determina a utilização de estruturas tubulares circulares. É crescente a concepção de pórticos formados por colunas tubulares e as tradicionais vigas de seção I. Esse tipo de ligação ainda é pouco estudado no Brasil, e esse trabalho busca avançar no ente

6. Comparative study of steel purlins in conventional beams, in planar trusses and multi-planar trusses / Estudo comparativo entre terças de aço, convencionais em vigas, em treliças planas e em treliças multiplanares
Steel roof systems are widely used in buildings that require large free internal spaces and small execution times, such as commercial and industrial warehouses and storage and distribution centers. The purlins have a considerable contribution in the roof system total weight composition. In this work was developed a study on the different types of purlins for

7. Análise numérica de ligações metálicas viga-coluna com coluna tubular circular / Numerical analysis of steel beam-to-column connection with circular hollow section column
As estruturas tubulares, muitas vezes, têm sua aplicação restrita a construções onde a concepção arquitetônica determina o seu uso, no entanto há algumas vantagens do ponto de vista estrutural que podem justificar a sua aplicação. A reduzida área exposta ao fogo e aos ambientes agressivos, boa resistência a compressão axial com baixa tendência

9. FADIGA EM ESTRUTURAS METÁLICAS TUBULARES SOLDADAS
Circular and rectangular hollow sections are used extensively in the field of the construction and mechanical engineering in all types of structures, such as offshore platforms, towers of communication, fluid conductors, bridges, footbridges and others, under different types of loading. These structures when submitted to cyclical loads, although in situation

10. Diagnóstico numérico de vigas Vierendeel formadas por perfis tubulares metálicos de seção circular / Numerical diagnosis of Vierendeel trusses made in steel circular hollow structural sections
Vierendeel trusses are framed structures having parallel chord members used in several types of buildings where lighting, ventilation and architectural definitions do not permit using cells with diagonal web members as in classic trusses. This work presents a study of Vierendeel trusses formed by hollow structural sections considering the global structure be

12. Estudo numerico-experimental de treliças tubulares planas para coberturas padronizadas para grandes vãos / Experimental and numerical study of hollow plane trusses for standardized roofs
This strucuture is applied mainly for supermarkets, large stores and industries. Initially, all stages involved on design of steel structure were discussed, especially the advantages and disadvantages of tubular structures. Through the study of existing roof systems, a new system using tubular steel sections was developed. To evaluate the structural behavior
