Jianzhu Gangjiegou Jinzhan, 2006 国内外关于钢骨混凝土柱的抗火性能试验和理论研究非常少。本文采用有限元方法对钢骨混凝土偏压柱的抗火性能进行研究,首先以相关试验数据对分析理论与计算程序的可靠性进行验证。在此基础上,在标准火灾升温作用下用数值计算方法对钢骨混凝土偏压柱的混凝土强度、钢骨强度、钢骨含钢率、长细比、偏心率、截面尺寸和受火时间等高温极限承载力影响参数进行’计算分析,并分别给出了拟合计算式,可供钢骨混凝土偏压柱抗火设计参考。

Jianzhu Gangjiegou Jinzhan为提升内填充轻钢复合墙体的抗火性能，开展了2块双层石膏板覆面岩棉内填充非承重轻钢复合墙体的抗火试验研究，探究了不同填充层布置对墙体抗火性能的影响。试验结果表明：相较于空腔全填充墙体，龙骨无填充墙体受火过程中热翼缘温升更慢、冷热翼缘温差更小；龙骨无填充墙体的承重抗火性能优于空腔全填充墙体的承重抗火性能。同时，在荷载比为0.27的条件下，相较于空腔全填充墙体，龙骨无填充墙体的耐火极限提升了11.5%左右，且龙骨无填充墙体的施工更为简便。因此 ...

Unpacking value destruction at the intersection between public and private value
Public Administration, Volume 101, Issue 4, Page 1207-1226, December 2023., 2023 Abstract Public services do not always create value. Rather, when poorly organized and/or delivered, they can destroy value and make service users' lives worse. However, such “value destruction” is presently weakly conceptualized in public management theory. Consequently, this paper is devoted to the empirical examination of value destruction and hence

Journal of Traumatic Stress, Volume 36, Issue 2, Page 465-473, April 2023., 2023 Abstract The 2014 Hazelwood coal mine fire in the Latrobe Valley, Australia, distributed toxic smoke into surrounding communities over 45 days. This study investigated risk and protective factors associated with four trajectories of posttraumatic distress (resilient, recovery, delayed‐onset, chronic) among exposed adults.

Evidence-Based Complementary and Alternative Medicine, Volume 2016, Issue 1, 2016., 2016 Traditional Chinese medicine (TCM) still needs more scientific rationale to be proven for it to be accepted further in the West. We are now in the position to propose computational hypotheses for the mode‐of‐actions (MOAs) of 45 TCM therapeutic action (sub)classes from in silico target prediction algorithms, whose target was later annotated with Kyoto ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The demand for advanced aerospace components necessitates near‐α titanium alloys with enhanced high‐temperature performance and compatibility with additive manufacturing (AM). To address this, an in situ alloying strategy was employed to co‐modify a Ti‐6.5Al‐2Zr‐Mo‐V alloy with Si and Y during laser powder bed fusion.
