Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.

Repeatability and Parasitic Out‐of‐Plane Motion in Controlled Rocking Structures With Cylindrical Columns: Results From Triaxial Shake Table Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...
