Corner-supported modular steel buildings, made of volumetric bespoke prefabricated units,
are one of the most efficient construction systems for the next generation of prefabricated …

The behavior of steel structures is significantly affected by the connections between the steel
members. For this reason, special attention to the prediction of the joint rotational behavior is …

This work proposes topology optimization for steel I-beams, including consideration of
bolted beam-column connections with geometric and material nonlinear analysis. The aim is …

A substantial effort has been made in recent years to characterise the behaviour of semi-
rigid connections. Recent studies and modern codes, in particular EC3 and EC4, not only …

In the structural analysis of steel frames, joints are generally considered as rigid or hinged
considering their momenttransfer ability. However, the first studies conducted with the …

The present paper aims to analyze the mechanical behavior of bolted steel beam-to-column
joints with extended endplate and different stiffeners subjected to bending moment. These …

This paper deals with the formulation of cruciform finite elements that model 2D steel joints
for frame analysis. Three different cases are contemplated: single rectangular panels …

Connections are a key component of steel structures. Current methods of analysis of steel
frames mostly rely on approximate joint models based on zero-length rotational springs or …

The equivalent T-stub method is frequently employed in infrastructure projects, including
bridge engineering, to simplify bolted connection analysis. However, steel connections …

The accurate simulation of steel structures requires a precise model of the joint behaviour.
The methods proposed by the steel codes are based on either rotating springs or involved …
