Brittle failure in RC masonry infilled frames: The role of infill overstrength [PDF]

Engineering Structures, 2018
Abstract The interaction between an infill panel and a reinforced concrete (RC) column can lead to the brittle failure of the structural element. A novel combination of cutting-edge analytical modelling approaches for masonry infills and RC elements is employed to simulate five experimental tests (three infilled and two bare) characterized by brittle

Design, Experimental Characterization, and Numerical Assessment of a Resilient Prestressed Lead Damper

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
The prestressed lead damper (PS‐LED) is a novel hysteretic damper that leverages the friction developed between a straight steel shaft and a lead core to dissipate seismic energy. A key feature of the device is the possibility to adjust its axial force by changing the prestress applied to the lead core, enabling customization to meet specific design ...

Multiparametric modeling of infill shear walls with additionally made openings

Structural Concrete, Volume 26, Issue 6, Page 8716-8740, December 2025.
Abstract The paper deals with the implementation of additional openings in reinforced concrete infill shear walls from the point of view of structural analysis. In the introductory part, the current state of knowledge in the methods of analysis of this issue is discussed, and their advantages or shortcomings are pointed out.

Validation of a simplified micromodel for analysis of infilled RC frames exposed to cyclic lateral loads [PDF]

, 2016
An RC frame structure with masonry infill walls (‘‘framed-masonry’’) exposed to lateral loads acts as a composite structure. Numerical simulation of framed-masonry is difficult and generally unreliable due to many difficulties and uncertainties in its ...

Two Cycles of Devonian–Triassic Extension and Compression in the Altai Accretionary Wedge: Insights From Tsogt Core Complex

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...

Semi‐Automated Operational Modal Analysis With Fuzzy Clustering for Structural System Identification

Engineering Reports, Volume 7, Issue 10, October 2025.
This study presents a semi‐automated operational modal analysis method combining fuzzy clustering and similarity filtering for structural identification. Applied to a six‐story RC building in Iran, the approach achieves < 5% frequency error, validated via Modal Complexity Factor, advancing automation and reliability in structural health monitoring ...

Influence of infill panels on the seismic behaviour of a r/c frame designed according to modern buildings codes [PDF]

, 2012
It has been broadly shown that presence of infill panels as closing elements of R/C frame buildings has a significant influence on global structural behaviour.

Seismic Capacity and Performance of Waffle‐Flat Plate Structures Under Near‐Fault Ground Motions: Bidirectional Shake Table Tests

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 12, Page 3069-3089, 10 October 2025.
ABSTRACT A reinforced concrete waffle‐flat plate structure was subjected to a sequence of bidirectional near‐fault ground motions on a shake table until collapse. The test specimen was designed under current building codes and assigned a region of moderate seismicity.
