Review on the modelling of joint behaviour in steel frames
TL;DR: In this article, the authors present a review of the analysis methods of semi-rigid joints, prediction methods for the mechanical behaviour of joints, and mathematical representations of the moment-rotation curve.

Nonlinear dynamic analysis of steel portal frames with semi-rigid connections
TL;DR: In this paper, a semi-rigid low-rise portal frame nonlinear dynamic analysis is presented to represent the dynamical behaviour of semirigid joints under dynamic actions implemented on the ANSYS finite element software, which included the geometrical nonlinearity and considered the influence of a nonlinear and hysteretic connection stiffness.

Perturbation Based Stochastic Finite Element Analysis of the Structural Systems with Composite Sections under Earthquake Forces
TL;DR: In this paper, the perturbation based stochastic finite element analysis can provide probabilistic behavior of a structure, only the first two moments of random variables need to be known, and should therefore be suitable as an alternative to Monte Carlo simulation (MCS) for realizing structural analysis.

A practical design method for semi-rigid composite frames under vertical loads
Jing-Feng Wang,Guo-Qiang Li +1 more
TL;DR: In this article, the rotational stiffness of beam-to-column connections for calculating the deflection of the frame beams and the effective length factor of columns are also determined, and the accuracy of the proposed design method is verified by a pair of tests carried out on full-scale semi-rigid composite frames.

Experimental assessment of the ductility of extended end plate connections
TL;DR: In this paper, an experimental investigation of eight statically loaded extended end plate moment connections was undertaken at the Delft University of Technology to provide insight into the behaviour of this joint type up to collapse.
