In recent decades, wind turbines (WTs) have experienced unprecedented growth, and their increased installations in mountainous regions has significantly elevated the associated seismic risk. However, understanding of wave propagation ground motion attenuations, particularly considering source-path-site effects, remains limited, becoming a key bottleneck design WTs. To address this, this paper assesses performance WTs by analyzing combined effects source characteristics, paths, local site...
In order to investigate the influence of coexistence clay and silt on compression characteristics sand, one-dimensional consolidation tests were carried out reconstituted saturated sand-silt-clay mixtures with a constant initial void ratio, effects fines content (FC) clay-silt ratio (CS) mixed soils studied. The mechanism experimental results was additionally explained from microscopic perspective. test show that: compressibility soil increased increase in FC; change rule different CS is...
Abstract With consideration of seismic resilience, damage nonstructural components (NSCs) attracts significant attentions. Most previous studies focused on dynamic behaviors NSCs under horizontal excitations. Near‐fault earthquakes, however, have strong vertical ground motion components, but few assessed their influence NSCs. In this study, the responses unanchored near‐fault earthquakes with are investigated. Response history analyses steel moment frames different heights performed and...
Loess soils undergo collapse when the material is loaded and wetted, which leads to engineering problems disasters. To understand better mechanisms that govern loess loess-like deposits under complex stress paths, a distinct element model has been established. A contact considering water content effect introduced for structural was used cement contacted particles together simulate unsaturated biaxial compression conditions. The numerical tested different wetting loading i.e., loading-quick...

It is a great challenge to detect in-situ high-frequency vibration signals for extreme environment applications. A highly sensitive and robust sensor desired. Among the many piezoelectric materials, single-crystal lithium niobate (LiNbO3) could be good candidate meet demand. In this work, novel type of micro-electro-mechanical system (MEMS) based on single crystalline LiNbO3 thin film demonstrated. Firstly, four-cantilever-beam MEMS was designed optimized with parametric method. The...
Metallic yielding devices have been widely used for improving seismic performance of buildings. However, metallic dampers currently in use are often attached to structural systems through brace components, potentially causing conflicts with architectural requirements. In this study, a damper that utilizes the angular deformation generated at beam‐column connection under lateral loads is proposed. The input energy can be dissipated inelastic deformations hyperbolic‐shaped steel bars. Firstly,...
What's known on the subject? and What does study add? Recent studies have indicated that high mobility group box 1 (HMGB1) is related to development progression of human carcinomas. However, further were required confirm roles played by HMGB1 in clinical prostate cancer treatment. We investigated relationship between expression characteristics cancer, also evaluated significance as a prognostic factor for biochemical recurrence-free survival after radical prostatectomy.• To investigate (PC)...
