Hybrid simulation of steel frames with semi-rigid connections
Fully-welded connections for earthquake resistance of steel frames are costly and their performance is adversely affected by weld defects and low-cycle fatigue. An alternative to welded connections is the bolted top and seat angle connection. The latter configuration can be designed to exhibit …

Modelling and analysis of composite structures with semi-rigid connections
… normally noncomposite. The steel beam-to column connections are either designed as pinned or designed as rigid. Recent research has shown that semi-rigid joint behaviour may be achieved in composite joints by considering only a small amount of reinforcement over the connections. However due to …

A study of semi-rigid connections between longspan joists and columns
… on the restraint values of beam-column connections, the beam is often over designed by failing to take advantage of partial continuity. If the degree of restraint of a beam-column connection can be determined, the optimum beam moment can be derived and then an optimum or economic beam …

The influence of semi-rigid connections on the behaviour of slender structures
… structures, it is normally assumed that the connections of the structures are either rigidly fixed or perfectly pinned. However, the real situation is that most connections often exhibit semi-rigid characteristics. This no doubt has a significant influence on the overall behaviour of the …

The Influence of Semi-Rigid Connections on the Behaviour of Beam and Column Structural System
… and the beam end connectors which provide semi-rigid connections between the beams and the uprights. The connections in storage systems are often boltless tabs. These tabs are engaged into perforations in the cold-formed upright sections at variable heights determined by the perforation …

The influence of semi-rigid connections on the non-linear behaviour of pallet rack and scaffold structures
… of framed structures have assumed that the connections between uprights and beams are either rigid or pinned. In reality all joints exhibit flexibility and can be considered as semi-rigid. The published work in this thesis provides some of the most extensive work on the effects of semi-rigid …

An experimental study on the cyclic behaviour of riveted stiffened seat angle connection with concrete encasement.
… constructed using what are considered today as semi-rigid or flexible types of connections. A concrete encasement was typically added to columns in the past for the sole purpose of fire protection. The behaviour of semi-rigid connections under cyclic loading and the contribution to seismic …

High strength steel for seismic resistance of beam-to-column connections: novel metal investigation
… of structures, and rotational capacity of connections made by HSS, current codes recommend that connections remain in the elastic range. Under seismic events, high demands for local and global deformation are imposed on structural elements, connections and details. Designers should look …

Analysis and comparison of connections in steel structures
The topic of connections is often given only limited attention in structural analysis and design of buildings, despite the fact that they can play a critical role in the structure. It is customary practice in the U.S. for the structural engineer to design the structural members, but leave the …

Modeling of Hysteretic Behavior of Beam -Column Connections Based on Self -Learning Simulation
… is applied to inelastic hysteretic behavior of connections. In the proposed model, two energy-based internal variables are introduced to expedite the learning of hysteretic behavior of materials or structural components. The model has significant advantages over conventional models in that it …

An Investigation of Beam-to-Column Connections for Composite Structural Systems
I-beams with angle connections are becoming the standard framing method for composite structures. We claim that closed sections are often a more appropriate member selection. We also present the cuff connection; a novel beam-to-column connection element suited to closed structural members. We …

Design optimisation of steel portal frames using modified distributed genetic algorithms
… process and they are assumed to have rigid and/or semi-rigid connections. The design optimisations are conducted according to therequirements of both BS 5950 and EC3 codes of practice. A stiffness matrix is developed for a non-prismatic member that is involved in the analysis process.

Seismic behavior of semi-rigid steel frames
The widespread and unexpected damage to welded connections during recent earthquakes led to the investigation of alternatives for the construction of steel frames in seismic areas. Bolted semi-rigid connections have been recognized as an attractive alternative to welded connections. However, …

Hybrid mathematical and informational modeling of beam-to-column connections
… been carried out by idealizing beam-to-column connections as either rigid or pinned. Although some advanced analysis methods have been proposed to account for semi-rigid connections, the performance of these methods strongly depends on the proper modeling of connection behavior. The primary …
