Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Seismic Retrofit of Steel Truss Bridge Using Buckling Restrained Damper
Applied Sciences, 2019 Buckling Restrained Bracings (BRBs) are widely used to improve the seismic behavior of buildings. They are employed for bridges as well, but their application in this respect is limited. BRBs can also be used as a function of the individual damper rather

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Seismic behavior of the contents of seismically isolated buildings
, 2021 Sismik izolasyon, gelişmekte olan depreme dayanıklı bir tasarım teknolojisidir. Özellikle ankastre binalara kıyasla kat ivmelerini azaltır. Böylece, binaların içeriğini korumada çok başarılıdır. Önceki çalışmalarda, içerik korumanın kapsamı yalnızca kat ivmelerinin incelenmesi ile yapılmıştır.
