高层建筑火灾防控与设计研究

open access: yes智能城市应用, 2023
随着社会的发展,高层建筑逐渐成为城市中一道亮丽的风景线。它的出现,在方便人们生活的同时,也带来了很多安全隐患。近年来,高层建筑火灾事故频发,造成了重大人员伤亡和财产损失。究其原因,主要是因为高层建筑人员密度大,一旦发生火灾,很难迅速疏散人群和灭火扑救。因此,加强高层建筑火灾防控与设计研究,对于提升我国建筑消防安全水平、保障人民群众生命财产安全具有十分重要的意义。文章从高层建筑的主要火灾隐患入手,针对高层建筑火灾防控与设计方案进行研究,旨在为相关人员提供参考。

火灾后混凝土结构修复方案研究

open access: yes智能城市应用, 2022
随着国内建筑行业技术水平的不断提升,在解决工程建设过程中疑难问题的同时,大量的新工艺、新方法、新材料也在不断出现,施工现场因建筑材料燃烧、电线短路等引发的火灾问题也在近几年陆续发生,造成了严重的人员伤亡和经济损失。为了确保建筑后续的正常施工和设计使用寿命,在建工程火灾后构件的修复工作显得尤为重要。文章结合1个过火后混凝土框架结构地下室,对火灾原因进行分析,对过火区域构件进行初步和详细评级,采取增大截面法和置换法对相关过火构件进行修复。

Fire risk communication in the urban informal sector: Evidence from traditional marketplaces in Accra, Ghana

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 14, Issue 4, Page 297-320, December 2023., 2023
Abstract Urban marketplace fires in Ghana are chronic, devasting in economic losses and disproportionately impacting informal sector workers. Yet, the scholarly works on urban disasters have focused on hydrometeorological and other man‐made disasters to the neglect of marketplace fires, particularly the challenges in risk communication between ...

Emergency management and the final frontier: Preparing local communities for falling space debris

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 14, Issue 3, Page 247-266, September 2023., 2023
Abstract Global dependence on satellite technologies, along with expanding space exploration, and commercial space travel have made rocket launches routine modern‐day events. As a result, there is an increasing probability of civilian casualty from rocket launch anomalies, or from falling space debris already in orbit.

Modeling mammal response to fire based on species’ traits

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Fire has shaped ecological communities worldwide for millennia, but impacts of fire on individual species are often poorly understood. We performed a meta‐analysis to predict which traits, habitat, or study variables and fire characteristics affect how mammal species respond to fire.

International media coverage promotes donations to a climate disaster

open access: yesDisasters, Volume 47, Issue 3, Page 725-744, July 2023., 2023
The Australian bushfires in 2019–20 triggered massive amounts of charitable giving from the community. This study applied agenda‐setting theory to examine if and how disaster news coverage influenced public donations in response to the crisis. A survey of 949 Australians found that people perceived news coverage of the event to be a strong influence on
