Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit

Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.
