Seismic Performance of Lightweight Steel Shear Walls With Gypsum Sheathing: Experimental Investigation

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 11, Page 2900-2926, September 2025.
ABSTRACT This study investigates the structural performance of cold‐formed steel (CFS) shear walls sheathed with gypsum panels, in accordance with the forthcoming Eurocode 8 seismic design guidelines for ductility class 3 (DC3) buildings. Utilizing a multiscale experimental approach, the research involved material testing, component‐level evaluations ...

Seismic Design of Steel Chevron and Split‐X Concentrically Braced Frames

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 10, Page 2565-2585, August 2025.
ABSTRACT This paper aims to (1) investigate how various design parameters affect seismic response of steel chevron and split‐X braced frames, (2) advance understanding of their seismic behaviour and (3) propose new system‐specific guidelines for accurately estimating their seismic demands and for achieving enhanced seismic performance.

Evaluation of Seismic Acceleration Amplification Factors for Building Nonstructural Components Based on Coupled Analysis of Structure‐Nonstructural 2‐DOF System

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 7, Page 1934-1951, June 2025.
ABSTRACT In this study, seismic demand on nonstructural components (NSCs) was analyzed using a combined structural‐nonstructural 2‐degree‐of‐freedom (2‐DOF) model. This model was specifically employed to incorporate coupling effects, which arise from the dynamic interaction between supporting structures and NSCs. The effect of structure‐NSC coupling on

Application of low‐emission cement CEM II/C in concrete made with low‐effort processed recycled aggregates

Structural Concrete, Volume 26, Issue 3, Page 2881-2899, June 2025.
Abstract The present study investigates the applicability of recycled concrete aggregates (RCA) for use in structural concrete made with low‐emission cement CEM II/C‐M (global warming potential of 377 kg CO2,eqv.). The aim is to show the potential of RCA processed with minimal energy, water, and economic expenditure.

Seismic Design of Hybrid Coupled CLT Shear Walls with Steel Link Beams

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 6, Page 1520-1539, May 2025.
ABSTRACT This study proposes a seismic design method for hybrid coupled cross‐laminated timber (CLT) shear walls with steel link beams as the lateral load‐resisting system for mass timber buildings. A force‐based seismic design method was proposed as a preliminary design process to determine the primary structural components. To inform the selection of

Numerical analysis and parametric study on stainless steel replaceable shear link under cyclic loading

Discover Civil Engineering
This study presents a numerical comparison of replaceable shear link beams made of two grades of stainless-steel duplex S2205 and austenitic S31608, to that of conventional cast steel (G20Mn5QT) under cyclic seismic loading. 3D finite element models were

Enhancing the seismic stability of buckling‐restrained steel braced frames in subduction interface seismic regions using viscoelastic dampers

Earthquake Spectra, Volume 41, Issue 2, Page 1364-1388, May 2025.
This article proposes a stability‐enhanced alternative to traditional buckling‐restrained steel braced frames (BRBFs) for application in tall‐rise steel buildings located in high seismic regions. The viscoelastic (VE)‐BRBF is a BRBF featuring V or inverted‐V bracing configurations and integrates vertically aligned VE dampers at beam–brace intersections

Overstrength and Response Modification Factor in Low Seismicity Regions

Journal of the Earthquake Engineering Society of Korea, 2006
Seismic design codes are mainly based on the research results for the inelastic response of structures in high seismicity regions. Since wind loads and gravity loads may govern the design in low seismicity regions in many cases, structures subjected to design seismic loads will have larger overstrength compared to those of high seismicity regions ...

Shake table testing of a full‐scale three‐story seismically resilient steel‐framed building with reconfigurable lateral force‐resisting systems

Earthquake Spectra, Volume 41, Issue 2, Page 1389-1420, May 2025.
Shake table testing is a costly endeavor, often requiring construction of large‐scale 3D specimens to allow system stability, though the focus may be solely on understanding the behavior of select components, subsystems, or contents. To minimize this burden on future researchers using the six‐degree‐of‐freedom (DOF) Large High‐Performance Outdoor Shake

Seismic Design and Fragility of Self‐Centering Bridge Bent With Replaceable Stretch Length Anchors

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 5, Page 1433-1453, 25 April 2025.
ABSTRACT Seismic performance assessment of a modified two‐column bridge bent of an existing bridge is presented. The columns of the existing bridge are posttensioned with high strength steel bars. The modified bridge bent combines self‐centering, from unbonded posttensioned (PT) bars with low initial posttensioning stress in the columns, with energy ...
