Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Influence of Masonry Infill on Seismic Design Factors of Reinforced-Concrete Buildings

open access: yesShock and Vibration, 2022
Infill walls are the most common separator panels in typical reinforced-concrete (RC) frame structures. It is crucial to investigate the influence of the infill walls on the earthquake behavior of RC frames.

Experimental assessment and retrofit of full-scale models of existing RC frames [PDF]

open access: yes, 2002
PSD tests on two full-scale models of existing non-seismic resisting RC frame structures are described. The testing program covered several aspects, namely assessment of seismic performance of existing frames without and with infill panels ...

Inherently Disordered Auxetic Metamaterials

open access: yesAdvanced Science, EarlyView.
Inherently disordered auxetic metamaterials based on random chiral Delaunay triangulations are designed and investigated using numerical simulations and experimental tests. These disordered frameworks exhibit orthotropic behavior and a large negative Poisson's ratio (ca.

Effects of Single and Multi Openings in Brick Infills on the Seismic Response of Infilled RC Frames

open access: yesMATEC Web of Conferences, 2018
Many researchers have performed a lot of studies of the seismic behavior reinforced concrete (RC) frame with masonry infill. They found that masonry infill affects the lateral strength, stiffness and ductility performance of the RC frame structures ...

Numerically based proposals for the stiffness and strength of masonry infills with openings in reinforced concrete frames [PDF]

open access: yes, 2016
Aimed at investigating the effect of openings on the in-plane behaviour of masonry infills in reinforced concrete frames, a parametric study is presented based on model calibration via experimental tests.

Pellet Printing for Soft Robotic Devices

open access: yesAdvanced Science, EarlyView.
Fused Granulate Fabrication (FGF) is established here as a reliable method for fabricating soft, airtight robotic devices. Through coordinated optimization of hardware, material selection, and process parameters, this approach enables high‐speed printing of thermoplastic elastomers with silicone‐like softness and modulus.

Seismic Evaluation of Advanced Reinforced Concrete Structures

open access: yesAdvances in Materials Science and Engineering, 2022
Many reinforced concrete frame buildings were developed and constructed in Coimbatore zone III before 2002. In 2002, the seismic code IS 1893 was updated. As a result, structures constructed earlier in 2002 do not meet the codal criterion.

The use of FRPs in seismic repair and retrofit: experimental verification [PDF]

open access: yes, 2001
The application of FRPs in the seismic repair and retrofit of structures is addressed. The results from a few tests on full-scale structures, repaired and/or retrofitted with composites, performed at the ELSA laboratory are presented and ...

Analytical modeling of masonry-infilled RC frames retrofitted with textile-reinforced mortar [PDF]

open access: yes, 2014
This paper proposes an analytical approach for modeling the behavior of textile-reinforced mortar (TRM)-strengthened masonry-infilled reinforced-concrete (RC) frames under seismic loading.
