液化石油气泄漏的危险性分析及其事故后果评价方法

陈思凝,孙金华,王青松

《中国工程科学》 2005年第7卷第9期页码 61-64

摘要：

液化石油气（LPG）在其运输和存储过程中存在着各种与火灾和爆炸相关的危险性。由于LPG的泄漏可能导致包括闪火，不可控蒸气云爆炸，沸腾液体膨胀蒸汽爆炸等一系列灾害的发生，针对上述的各种灾害的具体发生条件及其危险性进行了分析；在事故后果评价中采用量化风险分析，提出了沸腾液体膨胀蒸汽爆炸和不可控蒸气云爆炸对周围人员可能造成伤害的评价方法。

Assessment of robustness of structures: Current state of research

Colin BRETT, Yong LU

《结构与土木工程前沿（英文）》 2013年第7卷第4期页码 356-368 doi: 10.1007/s11709-013-0220-z

摘要： The concept of structural robustness and relevant design guidelines have been in existence in the progressive collapse literature since the 1970s following the partial collapse of the Ronan Point apartment building; however, in the more general context, research on the evaluation and enhancement of structural robustness is still relatively limited. This paper is aimed to provide a general overview of the current state of research concerning structural robustness. The focus is placed on the quantification and the associated evaluation methodologies, rather than specific measures to ensure prescriptive robustness requirements. Some associated concepts, such as redundancy and vulnerability, will be discussed and interpreted in the general context of robustness such that the corresponding methodologies can be compared quantitatively using a comparable scale. A framework methodology proposed by the authors is also introduced in line with the discussion of the literature.
