Effects of Vertical Irregularity on Transverse Reinforcement Spacing in Reinforced Concrete Columns to Avoid Shear Failure Subjected to Seismic Behavior

Buildings
As a result of the 2017 Pohang earthquake, numerous piloti-type structures incurred damage, and the cause was attributed to the wide spacing of transverse reinforcement. Improper spacing of transverse reinforcement can lead to brittle failure of columns,

Collapse Time of Reinforced Concrete Buildings with Brittle Columns

Journal of Asian Architecture and Building Engineering, 2018
Buildings with brittle columns are in danger of gravity load collapse and may be hazardous in the event of future earthquakes. To plan for building evacuation, the time required for such buildings to collapse must be known.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Inversion analysis of M-C criterion parameters of rock based on uniaxial shearing failure

Yantu gongcheng xuebao, 2017
Based on different shear failure modes in rock uniaxial compression tests, the relationship among the uniaxial compressive strength, cohesion and internal friction angle is deduced by using the limit analysis method.
