    Methods for Progressive Collapse Analysis of Building Structures Under Blast and Impact Loads

    Abstract: Progressive collapse of building structures under blast and impact loads has attracted great attention all over the world.Progressive collapse analysis is essential for an economic and safe design of building structures against progressive collapse to blast and impact loads. Because of the catastrophic nature of progressive collapse and the potentially high cost of constructing or retrofitting buildings to resist it,it is imperative that the progressive collapse analysis methods be reliable. For engineers their methodology to carry out progressive collapse uation need not only be accurate and concise,but also be easily used and works fast.Thus,many researchers have been spending lots of effort in developing reliable,efficient and straightforward progressive collapse analysis methods recently. In the present paper,current progressive collapse analysis methods available in the literature are reviewed.Their suitability applicability and reliability are discussed.Our recent proposed new method for progressive collapse analysis of reinforced concrete frames under blast loads is also introduced.
    建筑结构在冲击负载作用下连续倒塌分析方法

    摘要:建筑物在冲击负载作用下的连续倒塌已经引起了全世界的极大关注。对于一个经济的,安全的,能够抵抗冲击负载作用下连续倒塌的建筑结构设计,连续倒塌分析是必不可少的。因为连续倒塌的灾难性特点,和为了抵抗它而潜在的建造和改造建筑物的高额费用,所以连续倒塌分析方法是绝对必要且可信的。对于工程师们而言,他们估算连续倒塌的方法不仅仅要求精确和简要,而且容易上手,立竿见影。因而,最近许多研究者都在发展可靠有效和直接的连续倒塌分析方法上花费了很多的精力。在最近的干物上,当前在文献资料中找得到的关于连续倒塌的分析方法被重新审阅。人们广泛讨论它们的适宜性、适用性和可靠性。我们也提出了最近刚刚完成的关于钢筋混凝土框架在爆破荷载下的连续倒塌新分析方法。
