Combined Vertical and Horizontal Components of Near‐Source Earthquakes and Impact on Base‐Isolated Structures

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 781-803, March 2026.
ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

Influence of Masonry Infill Wall Position and Openings in the Seismic Response of Reinforced Concrete Frames

open access: yesApplied Sciences, 2022
It is now widely recognized that the masonry infill frame used in reinforced concrete structures (RC) greatly enhances both the rigidity and strength of the surrounding frame.

Fuzzy Fragility Analysis of Structures with Masonry Infill Walls [PDF]

open access: yesThe Open Construction and Building Technology Journal, 2012
In this work fragility analysis of reinforced concrete and steel structures withinfill walls is performed.For this purpose a fuzzy-based fragility assessment framework for evaluating 3D framed structures is proposed taking into account various sources of uncertainty.

Building Back Better Following the 2023 Kahramanmaraş Earthquake Sequence: Repair and Retrofit of Damaged Residential Reinforced Concrete High‐Rise Buildings

open access: yesEarthquake Spectra, Volume 42, Issue 1, February 2026.
Earthquakes have caused, and will continue to cause, damage to the built environment, resulting in casualties, economic losses, and long‐term societal impacts. One approach to decreasing future losses is limiting the damage that buildings experience during an earthquake and speeding up their recovery by following the “build back better” principle.

Database and Geometrical Characterization of 3D Stone Masonry Wall Microstructures

open access: yesEarthquake Spectra, Volume 42, Issue 1, February 2026.
This paper presents the first database of 3D microstructures of stone masonry walls, where masonry microstructure is defined as the shape, size, and layout of the stone units within the wall. The database includes 36 walls representing various masonry typologies as defined by the Italian code, with different leaf configurations (one‐, two‐, and three ...

Influence of Infill Wall Configuration on Failure Modes of RC Frames

open access: yesShock and Vibration, 2018
An improper configuration of masonry infill walls in RC frame may lead to short column effect on the columns, which is harmful to the seismic behavior of the structure.

Experimental Investigations and Microstructural Characterization of Construction Materials of Historic Multi-Leaf Stone-Masonry Walls

open access: yesHeritage, 2021
In order to correctly define the pathology of multiple-leaf stonemasonry walls and determine the appropriate interventions for its conservation and preservation, comprehensive studies on its building materials should be carried out since the overall ...

Experimental and Analytical Study of Masonry Infill Reinforced Concrete Frames Retrofitted with Steel Braces [PDF]

open access: yes, 2004
In the present work a seismic retrofitting technique is proposed for masonry infilled reinforced concrete frames based on the replacement of infill panels by K-bracing with vertical shear link.

Geometric Limits for the Seismic Design of Unreinforced Masonry Fence Walls

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 1, Page 130-149, January 2026.
ABSTRACT Current seismic design standards require masonry free‐standing walls to comply with regulations for masonry structural walls. Applying these current seismic design standards to fence walls (free‐standing walls) may be inappropriate due to the different restraint conditions between fence walls and structural walls.
