Investigation on Punching Shear Capacity of Hollow Slab-column Connection

IOP Conference Series: Materials Science and Engineering, 2018
To investigate the punching shear capacity of cast-in-situ reinforced concrete hollow slab-column connections under the unbalanced bending moments, a series of specimens were tested and analyzed in this paper. Hollow ratio, direction of moment, tube layout pattern and other factors are considered in the experiment.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Influence of the Distribution and Level of Post-Tensioning Force on the Punching Shear of Flat Slabs

Designs, 2022
Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection is always vulnerable to critical punching shear; thus, it is necessary to investigate the effect of various parameters on the ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Dynamic Loading Regulates Meniscus‐Like Matrix Production in Human Mesenchymal Stromal Cell‐Seeded PET Scaffolds

Advanced Healthcare Materials, EarlyView.
Dynamic compression enhances mesenchymal stromal cell proliferation in nonwoven PET scaffolds under chondrogenic differentiation conditions and triggers mechanosensitive transcriptional programs associated with extracellular matrix remodeling. These findings highlight the potential of mechanically stimulated PET scaffolds as a promising platform for ...

Effect of mid-thickness rebar mesh on the behavior and punching shear strength of interior slab–column connection

HBRC Journal, 2016
Punching shear failure is a major problem encountered in the design of reinforced concrete flat plates. The utilization of shear reinforcement via shear studs or other means has become a choice for improving the punching shear capacity.
