Change in cyclone disaster vulnerability and response in coastal Bangladesh
Disasters, Volume 48, Issue 2, April 2024.The number of deaths owing to tropical cyclones in Bangladesh has significantly reduced. Category 4 Cyclone Gorky in 1991 and Sidr in 2007 caused 147,000 and 4,500 deaths respectively, whereas Category 1 Cyclone Mora in 2017 resulted in six. Face‐to‐face interviews with 362 residents, participant observation, and focus‐group discussions answer a ...

Parliamentary questions, institutional change, and legislative oversight in a non‐Western context
Politics &Policy, Volume 52, Issue 2, Page 365-383, April 2024.Abstract This study examines how the Federal National Council (FNC), the parliament of the United Arab Emirates (UAE), transformed from a consultative body to a legislative institution through gradual and incremental changes. It argues that the increasing number of parliamentary questions led to legal, procedural, and behavioral changes in the FNC ...

Complicated grief and posttraumatic stress after loss and separation under terror conditions
Journal of Traumatic Stress, Volume 37, Issue 1, Page 154-165, February 2024.Abstract The lives of people in conflict areas are often characterized by the experience of traumatic events frequently accompanied by loss and separation. These can equally trigger symptoms of posttraumatic stress disorder (PTSD) and complicated grief (CG).

Jianzhu Gangjiegou Jinzhan, 2020 研讨了一种新型的蜂窝单撑杆型索穹顶结构,它的几何构形为上弦索,是一种蜂窝形网格布置,整个结构仍属于"拉索海洋和压杆孤岛"张拉整体的Fuller构想,但并不要求压杆垂直于水平面,而在径向平面内有一倾角,故可称为蜂窝单撑杆型索穹顶结构。采用节点平衡方程,对蜂窝单撑杆型索穹顶结构的预应力态提出了简捷分析法,详细推导了预应力索杆内力的一般性递推计算公式,并根据若干参数给出了大量的算例计算结果,以了解索穹顶预应力态的分布规律和受力特性。研究工作可为索穹顶结构的选型和设计提供参考。

Jianzhu Gangjiegou Jinzhan, 2018 提出一种基于损伤可控的梁柱节点(Web-Connected and Prestressed节点,简称WCP节点)。通过在梁端腹板设置连接钢板、摩擦耗能螺栓以及预应力筋,将梁柱连接在一起。为了研究该类节点的滞回性能、自复位能力和损伤特征,设计、制作并完成了4个足尺节点试件的低周往复试验,分别考虑了预应力筋的初始张拉力、高强度螺栓的预紧力以及拼接板的表面处理方式对节点性能的影响。试验结果表明:该类节点的破坏主要集中在拼接部分;节点通过螺栓的滑移变形提供了较好的耗能能力;预应力筋能够增强节点的刚度 ...

Jianzhu Gangjiegou Jinzhan随着国内风电行业发展规模日益壮大，风机功率逐渐增大，对下部支撑结构的承载能力、稳定性能也提出了更高的要求，钢-混凝土混合结构塔筒（上部纯钢塔，下部混凝土塔）应运而生。然而，由于需要现场拼装、灌浆，因此其建造效率低且后期维护成本高。基于此，提出了一种新型预应力钢管混凝土格构式风电塔架代替原有的钢-混凝土混合结构塔筒，四角柱采用预应力中空夹层钢管混凝土，提升刚度的同时减少了钢材和混凝土的用量，便于运输和吊装。中空部分作为预应力孔道进行通长整体张拉，增加结构稳定性及轴向滞回性能 ...

Jianzhu Gangjiegou Jinzhan, 2022 设计了10个高强钢T形件的单向拉伸试验，分别研究了螺栓直径、螺栓线距、螺栓端距和钢材强度对T形件受拉力学性能的影响，试验结果表明：在试验参数范围内，T形件共产生螺栓破坏、联合屈服和翼缘屈服三种破坏模式；增大螺栓直径会显著提高T形件的初始刚度、屈服荷载、极限承载力和极限变形；增大螺栓线距有利于提高T形件的变形能力，但初始刚度、屈服荷载和极限承载力会有所降低；增加螺栓端距能小幅提高T形件的屈服荷载、极限承载力和极限位移，但对初始刚度影响不大；钢材强度对T形件的屈服荷载和极限承载力影响较大。另外 ...
