Connections are a key part of a steel structure and carrying them out properly is critical to achieve a safe and economical structure. Thus, establishing a solution requires knowledge of structural mechanics, ability to trace the flow of load in the beam and through the connection, experience and rational analysis of the design engineer. This paper presents a very brief history of connections, then types of connections usually used in design practice are described: angle connections, end plate connections and welded connections. In conventional analysis and design of steel framed structures joints are usually carried out under the assumption that they are either ideally pinned or fully rigid. However, experimental research shows that most connections used in current practice are semi-rigid type and their behaviour lies between these two idealized situations. Structural analysis models allow the joint representation with semi-rigid behaviour (ASRO, 2006). Eurocode 3 establishes three...

Composite connections in steel and concrete. I. Experimental behaviour of composite beam--Column connections1994 •
Steel industry is growing rapidly in almost all the parts of the world. The use of steel structures is not only economical but also eco friendly at the time when there is a threat of global warming. Long Span, Column free structures are the most essential in any type of industrial structures, and Pre-Engineered Buildings (PEB) fulfills this requirement along with reduced time and cost as compared to conventional structures. The work will involve the detailed design and Analysis of connections in Pre-Engineered Buildings (PEB). Further, Comparison between connections of PEB and Conventional Steel Buildings will be done.
Profile steel sheet concrete composite slab are gaining increasing usage in modern construction practice in many parts of world. But in India, composite deck construction is an emerging concept. Load carrying capacity of composite deck is associated with bond between steel and concrete, which is generally provided by embossment. Role of embossment, its standard dimensions and its ability to transfer horizontal shear for various profile configuration is not much explored in Indian context. Moreover, for each profile configuration and embossment pattern separate set of full scale testing is necessary. This paper focuses on innovative bond techniques as an alternative to embossments in profile sheets by relatively small scale test. A total of twelve composite specimens, each in set of two specimens are casted and tested under uniformly distributed load with varying interface connections. The connection patterns considered are: bolt with different orientation, semicircular bend and bolt combination, stiffener and fabricated embossment. Comparison of load carrying capacities from the tests is presented. Comparison of test result has been made and it is found that connection topology with semicircular bend and bolt combination performed better in terms of load carrying capacity than other topologies.
