CUT-OFF OF SEISMIC ENERGY

Journal of Physics of the Earth, 1973
When a chain-reaction-type fracture formation is postulated at a seismic source (OTSUKA, 1972), the seismic energy account turns out to be influenced by the activity of earthquakes with moderate magnitudes in contrast to the generally accepted idea that it is primarily controlled by the activity of major earthquakes.While this current idea is needed to

Carbon Dots: An Emerging Frontier for Green and Sustainable Civil Engineering Materials

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Traditional civil engineering materials (CE materials) are usually involved with high‐energy consumption during manufacturing, significant maintenance costs, and substantial environmental impacts throughout their life cycles. The progress of nanotechnology is catalyzing a green and sustainable transformation within the field.

A review of energy associated with coal bursts

International Journal of Mining Science and Technology, 2018
A coal burst is defined as a rapid expulsion of coal (and potentially gas) from the boundary of the roadway. Rock and coal fractures together with micro seismic vibration is a common occurrence during mining, however, it is very uncommon for coal and ...

Magneto--Acoustic Energetics Study of the Seismically Active Flare of 15 February 2011

, 2012
Multi--wavelength studies of energetic solar flares with seismic emissions have revealed interesting common features between them. We studied the first GOES X--class flare of the 24th solar cycle, as detected by the Solar Dynamics Observatory (SDO).

The EU's Strategy for Sustainability: A Landmark Turn With the European Green Deal?

European Policy Analysis, EarlyView.
ABSTRACT While the European Green Deal (EGD) has been widely recognized as a milestone in the EU's sustainability strategy, scholars disagree on the nature of the policy change it represents. Critics highlight its limited social and environmental ambitions, despite its portrayal as a “man on the moon” moment.

Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit

Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.
