方套方中空夹层钢管混凝土柱与钢-混凝土梁单边螺栓端板连接节点数值分析
Jianzhu Gangjiegou Jinzhan, 2020 为了揭示方套方中空夹层钢管混凝土柱与钢-混凝土组合梁单边螺栓端板连接的受力性能和破坏机理,通过ABAQUS有限元软件建立了该组合节点的数值分析模型,明确了材料本构关系模型和复杂接触问题。通过水平低周往复荷载试验验证了数值分析模型的准确性,对其破坏模式和滞回曲线进行了评价。考虑了几何参数、材料参数、荷载参数对节点水平荷载-水平位移曲线的影响,讨论了极限承载力和初始刚度的影响规律。研究表明,方套方中空夹层钢管混凝土柱与钢-混凝土组合梁单边螺栓端板连接节点具有良好的抗震性能和受力性能 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Jianzhu Gangjiegou Jinzhan, 2010 传统的设计和分析都将框架的梁柱节点处理成理想的刚接或铰接。然而,实际工程中的连接一般很难达到这两种理想状态,大部分连接的受力性能介于这两者之间,为半刚性连接。在组合框架中,组合楼板和纯钢梁柱端板连接节点组成了一种新的连接形式-半刚性组合连接。针对我国目前还没有关于平端板连接梁柱组合节点设计规定的现状,基于现有的研究成果,本文提出了平端板连接半刚性组合节点设计的方法和建议,可为我国相应规范的修订提供参考。

Jianzhu Gangjiegou Jinzhan, 2022 提出一种新型波纹侧板钢管混凝土组合柱-钢梁框架节点形式——在节点核心区沿钢梁上下翼缘方向设置贯通隔板，梁翼缘设置加强板，柱四角布置方钢管并沿高度方向焊接波纹侧板形成钢骨架，骨架腔内灌注混凝土。利用ABAQUS软件建立有限元数值模型，并与常规节点的滞回性能、受力特性和破坏模式进行对比，发现设置加强板能有效提高节点的承载力，且能使塑性铰沿翼缘外移，两类节点的滞回曲线均较为饱满，耗能性能和延性较好。分析加强板厚度、混凝土强度、柱钢材强度等因素对此类节点抗弯承载力的影响，结果表明：加强板厚度、钢梁钢材强度 ...
