1. Bearing failure in bolted sleeve connections with circular hollow sections under compression
Abstract This article analyzes sleeve connections between circular hollow sections. This type of connection is composed of two tubes connected by bolts to an inner tube with a smaller diameter, and explores the efficiency, aesthetics and resistance of hollow sections subjected to tension and compression. In previous researches, sleeve connections with aligne

2. Experimental investigation of bolted stiffened end-plate and bolted flange-plate connections
Abstract This paper describes the experimental performance of the bolted stiffened end-plate (BSEP) and bolted flange-plate (BFP) connections using European hot-rolled profiles and built-up profiles. Four connections are designed and constructed according to FEMA-350 and are performed under cyclic loading. The influence of using different member profiles (Eu

3. Numerical simulation of bolted connections
Abstract This article presents the modeling of a complete bolted connection based on a model with one bolt connecting two or three plates. Initially, the behavior of this model with one bolt is analyzed by comparing it with existing bibliography for 3 different types of applied load: tension, shear and a combination of these two. This model includes all nece

4. Reliability analysis of welded and bolted connections in cold-formed steel sections
Abstract This article shows a study of the level of reliability of welded and bolted connections in cold formed steel members, for some limiting states, adopted by AISI and Brazilian codes. The aim of this study is the assessment of the reliability index β for a variation of the nominal live-to-dead load ratios as well as comparison of the value found consi

5. 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

6. Numerical Study on Ultimate Behaviour of Bolted End-Plate Steel Connections
Abstract Bolted end-plate steel connections have become more popular due to ease of fabrication. This paper presents a three dimension Finite Element Model (FEM), using the multi-purpose software ABAQUS, to study the effect of different geometrical parameters on the ultimate behavior of the connection. The proposed model takes into account material and geome

9. Modular bridge timber trusses system: a good alternative to the Para State / Sistemas de treliças modulares para pontes de madeira: uma boa alternativa para o Estado do Pará
The Para state has an area of 1.253.164,49 KM POT.2; it has an abundant hydrography and nearly 19.253,35 Km of vicinal roads, that are cut by many rivers. In this context, the construction of bridges with small and medium spans is essential to the improvement of intercity and interstate transportation. The system of modular timber truss bridges, was already

11. Analyzes of the numerical answer of the bolted connections of cold-formed steel members / Análise da resposta numérica de ligações parafusadas em chapas finas e perfis formados a frio
A utilização de perfis formados a frio na construção metálica no Brasil vem crescendo de forma significativa. Dentro deste mesmo contexto, atenções especiais estão sendo direcionadas às ligações utilizadas neste tipo de perfil, pelo fato de as chapas que as constituem resultarem cada vez mais esbeltas em função da significativa redução na sua
