为准确评估钢管混凝土拱桥地震损伤,将拱桥系统视为串-并联体系,即将拱桥系统各关键体系进行串联,而不同关键体系单个构件之间则分别采用串联或并联形式。以某钢管混凝土拱桥为研究对象,通过时程分析和神经网络预测获得拱桥各构件地震响应值,基于Copula函数分别得到拱桥各关键体系易损性和整体系统易损性,并与基于一阶界限法的系统易损性进行对比。研究结果表明:通过神经网络预测可以获得准确的拱桥结构地震响应值,当PGA=0.4时,预测准确率超过90%,且随着PGA的增大,准确率逐渐提高;拱桥各关键构件体系中 ...

为了研究钢框架-型钢混凝土(SRC)自复位墙板结构的抗震性能,完成了钢框架-自复位SRC墙板子结构模型的低周往复加载试验,以研究其工作机理和失效机制。提出了基于宏观单元的非线性分析模型,并利用试验结果验证模型的准确性,研究结果表明该非线性分析模型能较好地模拟自复位SRC墙板的非线性行为。分别建立6层和15层钢框架-自复位SRC墙板结构的整体模型并进行增量动力时程分析(IDA)。以地面峰值加速度为地震动强度指标,以最大层间位移角为损伤指标,根据IDA结果得到不同极限状态下的易损性曲线,建立地震易损性矩阵 ...

The I Ching as a Potential Jungian Application: History and Practice
Abstract Swiss psychiatrist Carl Jung had a lifelong interest in the I Ching after discovering it in 1919. Jung’s interest in the I Ching is arguably more practical than purely theoretical or intellectual, and references to I Ching divination appear frequently in his various publications, seminars, letters and clinical practice records.

Highlights During the past 30 years, globally, the disease burden of stroke burden has decreased substantially; however, the disease burden of stroke attributable to high fasting plasma glucose (HFPG) failed to achieve a significant decline. The population‐attributable fraction of HFPG for stroke burden has been increasing across different regions ...

International media coverage of the Bolivian jaguar trade
Abstract The trade in jaguar body parts is viewed as an alarming threat to the jaguar, and there is the assumption that Chinese demand is driving the trade. However, there has been little analysis of the discourses around the trade both with respect to the Chinese public, internationally and in source countries.
