高温后方钢管混凝土节点抗倒塌机理分析和剩余承载力评估

Jianzhu Gangjiegou Jinzhan
钢管混凝土结构在服役的全寿命周期内可能遭受火灾、爆炸等极端灾害作用，从而引起局部或大范围的倒塌破坏。节点核心区域作为结构的关键受力部位，在遭遇火灾后会发生不同程度的高温损伤，因此有必要开展高温后该类结构的抗倒塌性能分析。本文以方钢管混凝土柱-H型钢梁外环板式节点作为研究对象，基于顺序热-力耦合方法采用ABAQUS软件中的通用分析模块Standard建立了高温后该类节点倒塌精细化数值模型，对比常温下该类节点的倒塌试验结果，分析了该类节点在经历不同的历史最高环境温度（200 ℃、400 ℃、600 ...

野生动物友好型农业研究与实践进展

野生动物学报
全球人口增长带来的粮食需求增加，导致农业用地不断扩张与农药化肥过量使用，这是造成野生动物生境丧失、破碎化及质量下降的主要原因之一。野生动物友好型农业（wildlife-friendly farming， WFF）作为一种新兴农业模式，为缓解农业发展与野生动物保护之间的矛盾提供了可行路径。本研究综述了国内外相关研究和实践经验，梳理了WFF的起源与概念，分析了其在实践中的进展，并详细阐述了通过改造农业景观为野生动物提供栖息地的多种策略、借助经济激励手段促进野生动物保护与控制农药化肥过度使用所形成的正反馈循环，
