Assessment of buildings response to earthquakes [PDF]
WIT Transactions on The Built Environment, 2009 Modern buildings are designed to withstand earthquake loads and to reduce the probability of a disastrous collapse or life-threatening damage due to strong earthquakes. Under medium-intensity earthquakes, the damage to buildings should be repairable, and no building damage or discomfort to the occupants should occur due to minor earthquakes.

A Refined Multi-Spring Model for Prestressed Precast Concrete Connections
BuildingsPrecast concrete with a moment-resisting frame with hybrid beam–column connections (HBC), which is featured by inelastic deformation induced by opening and closing of the interface between precast beam and column, has been emphasized in recent years ...

Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

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 ...
