Non-linear analysis of masonry infilled steel frame under in-plane loading using Multi Pier method

Case Studies in Construction Materials
In the event of an earthquake, the in-plane stiffness, strength, and energy absorption capacity of the lateral load-bearing system could be affected by the presence of masonry infill walls.

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

, 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.

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Seismic Retrofitting of RC Frames with RC Infilling [PDF]

, 2012
The effectiveness of seismic retrofitting of multi-storey multi-bay RC-frame buildings, by converting selected bays into new walls through infilling with RC, was studied experimentally at the ELSA facility at JRC, Ispra, and the results are reported here.

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

Deep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Modeling of masonry infilled RC frames with different aspect ratios using plastic hinge and equivalent strut

Journal of Engineering and Applied Science
The existence of diverse modeling approaches for masonry-infilled frames causes uncertainty among practicing engineers when seeking a definitive model for their design practice.

Numerical modelling of masonry-infilled reinforced concrete frames : model calibration and parametric study [PDF]

, 2014
Generally two methods are proposed for analyzing the infilled frames; Micro modelling approach which finite element method is used to take into account local effects in detail and Macro modelling approach which is a very simplified method that takes into

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

Developmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...
