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 ...

Seismic Performance and Finite Element Analysis of Reinforced Concrete Frames Considering a Masonry-Infilled Wall

Advances in Materials Science and Engineering, 2022
This study investigated the seismic performance of a 1/3 scale, three-story, and three-span RC frame subjected to static cyclic lateral loading. The failure process and mode were analyzed using the digital image correlation (DIC) method.

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 ...

Prediction of the Seismic Response of Multi-Storey Multi-Bay Masonry Infilled Frames Using Artificial Neural Networks and a Bilinear Approximation

Buildings, 2019
In order to test the reliability of neural networks for the prediction of the behaviour of multi-storey multi-bay infilled frames, neural network processing was done on an experimental database of one-storey one-bay reinforced-concrete (RC) frames with ...

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 ...

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.

Modeling of interactions between RC columns and masonry infill in buildings with a column‐sway mechanism

Japan Architectural Review, 2018
This study proposes a new analytical model to evaluate interactions between reinforced concrete (RC) columns and masonry infill. An infill is replaced by a diagonal strut and its width is defined by column/infill contact length.
