Jianzhu Gangjiegou Jinzhan, 2022 将偏心支撑框架中的消能梁段腹板替换为低屈服点钢材，形成低屈服点钢偏心支撑框架。为实现震后修复的功能，消能梁段与主体结构通过高强螺栓及端板进行连接。建立了单层支撑框架和高宽比为2的高层支撑框架，对比分析了普通钢偏心支撑框架与低屈服点钢偏心支撑框架的抗震性能。有限元分析结果表明，单层支撑框架在相同变形状态下，低屈服点钢偏心支撑框架中的框架柱、支撑轴力显著降低，非消能梁段弯矩和剪力均有降低。高层支撑框架中，中、大震状态下低屈服点钢偏心支撑框架的位移和基底剪力均低于普通钢偏心支撑框架的位移和基底剪力 ...

Jianzhu Gangjiegou Jinzhan, 2021 新型腹板开孔屈服耗能支撑具有良好的延性和耗能能力,将其应用于框架结构中,可提高框架的抗侧刚度,组成的支撑框架结构具有较好的耗能能力。采用ABAQUS有限元软件,研究了不同参数的耗能支撑与框架之间分别采用焊接连接和板铰连接组成的支撑框架结构的滞回性能。有限元分析结果表明:耗能支撑主要依靠端部工字钢开孔腹板的孔间板件弯曲屈服耗能,滞回曲线饱满。支撑框架耗散的能量随着耗能支撑耗散能量的增加而增加,加载前期,支撑框架主要由耗能支撑耗能。随着层间位移角的增大,梁柱部分进入塑性后 ...

EU Policy‐Making in the Digital Age: Major Trends and Insights From Public Policy Research
European Policy Analysis, EarlyView.ABSTRACT Has digitalization changed policy‐making dynamics at the European Union (EU) level? To investigate this issue, this article presents a scoping review of the literature on EU digital policy‐making. While much scholarship adopts a ‘Governance’ approach, two conceptually rich strands emerge: critical approaches, and digital sovereignty.

Rare Metals, EarlyView.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Rare Metals, EarlyView.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐
