STRUCTURAL CRASHWORTHINESS This aspect in the design of structures can be looked upon simply as the design of bomb shelters, deep below in the basements. In as much as it is to make the design of a car more crashworthy or container of hazardous materials spill proof. The survival of the WTC towers was designed for against impact of crashing objects. Unfortunately the effects of high temperatures arising from burning of large amounts of aviation fuel was too much. This aspect of design involves the understanding of the nature of collapse mechanisms that can arise and designing multiple paths for stress transfer. Safety pockets capable of providing safe retreat during the worse case scenarios - like safes in banks - could be a good things. Many habitat items can be used and designed for this too. In principal the sequential collapse and the ability of the structure to withstand partial failure under catastrophic loading including that arising from earthquake loads should be provided for in some measure. The plastic design of the structure as a whole, including considering the foundation and the soil in this can be done at not too big a cost.
