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 ...

Investigation of ground motion vertical and horizontal component effects on the IDA curves for the regular and irregular steel moment frames [PDF]
Journal of Structural and Construction Engineering, 2019 The effect of seismic vertical components on the seismic behavior of structural systems can be considerable. The vertical component of ground motion records can cause the brittle collapse of columns resulting in global collapse of structures. This effect

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 soil-structure interaction for pile supported systems [PDF]
, 2009 Civil engineering structures involve structural elements with direct contact with ground. When the external actions, such as earthquakes, act on these systems, neither the structural displacements nor the ground displacements, are independent of each ...

Analytical Pushover Curves for X-Concentric Braced Steel Frames
Buildings, 2022 In this work, analytical pushover curves for concentric braced steel frames with active tension diagonal bracings (X-CBF) are proposed. A pushover “spindle”, characterized by two trilinear analytical capacity curves defined for an X-CBF system subjected ...
