Flexural Plastic Hinge Length for Reinforced Concrete Frames [PDF]
Fayoum University Journal of EngineeringThe flexural plastic hinge (PH) length is a critical parameter for reinforced concrete (RC) frames subjected to lateral load. In this work, a review of past studies for introducing empirical equations for estimating the flexural PH length (lp) of RC ...

Plastic hinge locations in steel columns
Bulletin of the New Zealand Society for Earthquake Engineering, 2010 Some standards for the design of steel structures attempt to encourage column yielding at the member ends, rather than along the column length during inelastic action such as may occur during strong earthquake shaking. In this paper, effects of residual stress and stability are considered separately and then combined to obtain equations that are more ...

Seismic analysis of pile in liquefiable soil and plastic hinge [PDF]
Geotechnical Research, 2017 Liquefaction is one of the leading seismic actions that cause extensive damage to buildings and infrastructure during earthquakes. In many historic cases, plastic hinge formations in piles were observed at inexplicable locations. This project investigated the behaviour of piled foundations within soils susceptible to liquefaction by using numerical ...

MATEC Web of Conferences, 2019 Structures are expected to have ductile behavior under major earthquakes. One requirement to achieve this ductile behavior is when the structures have no shear failures in their elements.

Rigid plastic plates at large deformations
Vietnam Journal of Mechanics, 1985 The method developed in [8] is applied herein in order to obtain estimations of the load-deflection relationship of the hinge supported rectangular plates acted on by a uniformly distributed loading.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
