Directionality Scaling of Scalar and Vector Ground Motion Intensity Measures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The azimuthal directionality of earthquake ground‐motion intensity measures (IMs) is conventionally described by the ratios between the orientation‐independent maximum (RotD100) and median (RotD50) values over the horizontal plane. This study presents a refined characterization of the directionality of 31 IMs, including spectral accelerations (

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Development and Validation of a Seismic Design Method for Anchored Retaining Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Three‐Dimensional Analytical Model of a Podium Structure With Rocking Columns of Square Cross Section

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Allowing structural systems to uplift and rock during seismic excitation has emerged as an effective and inherently self‑centering form of seismic isolation. This paper develops a computationally efficient 3D analytical model suitable for the understanding of the behavior of rocking bridges.

Displacement Estimation of Structures With Flag‐Shaped Hysteresis Loops

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Time‐history analyses were conducted on single‐degree‐of‐freedom (SDOF) systems with flag‐shaped hysteresis loops using a far‐field ground motion suite to estimate peak displacements, Δp, and equivalent deformation cycles, Nc, associated with cumulative displacement demands.
