Baˇzant, Z.P., and Verdure, M. (2007). “Mechanics of Progressive Collapse: Learning from World Trade Center and Building Demolitions.” J. of Engrg. Mechanics ASCE 133, pp. 308–319.
Abstract: Progressive collapse is a failure mode of great concern for tall buildings, and is also typical of building demolitions. The most infamous paradigm is the collapse of the World Trade Center towers. After reviewing the mechanics of their collapse, the motion during the crushing of one floor (or group of floors) and its energetics are analyzed, and a dynamic one-dimensional continuum model of progressive collapse is developed.家园 这位是牛人 Z.P.Bazant，美国civil engineering的泰斗啊
曾经有幸经他指导过课题
家园 这里有直观的解释, 看看说的有没有道理? Mythbusters Ban 911 Topic On Discovery Channel Forum
The events of 9/11 will not be allowed to be debated and discussed and if they are they will be removed. The subject is sensitive and painful for us all and inappropriate for the Mythbusters forum. We appreciate you complying the guidelines.The Discovery Channel

家园 链接不通呀?
家园 老大，大佬，不要纠结这个事情吧 很明显是烧塌的，烈火熊熊，就算是岩石都要烧成岩浆，不塌才怪。
延伸到质疑米国航天局的登月计划，不管是真登天还是特效，都是米国人创造GDP的方式的一种，莫要纠结，何况登月计划板上钉钉是超级大国（美苏）真正的实力展示。
米国人忽悠911，是刺激基地组织尽快暴露的阴谋，基地沉不住气，再策划一下来证明，就被CIA一网打尽。
深海呀。
,干脆宣布:因管理不善,登月数据已经全部丢失
,让那些挑毛病的人彻底失业.
