In recent years, super high-rise buildings (>500 m) are developing very quickly and become an important frontier of civil engineering. The collapse resistance of super high-rise buildings subjected to extremely strong earthquake is a critical problem that must be intensively studied. This paper builds up a nonlinear finite element model of the tallest building in China, Shang- hai Tower (632 m), and proposes the modeling method and failure criteria for different structural elements. The dynamic char- acters of this building are then analyzed, and the possible failure modes and collapse processes due to earthquakes are pre- dicted, as well as the corresponding collapse mechanism. This work will be helpful in collapse prevention and the seismic design of super high-rise buildings.

亮点导读 素材翻新想象巧,结尾升华主题明  同样写居里夫人,同样写她的敬业精神,本文的魅力却是与众不同的。作者没有将她的事例简单地用作论据,而是加以想象,通过具体的工作场景来反映人物的思想与作风。可以说,素材翻新,熟中求巧,是文章成功的关键。  文章重视细节的安排。比如写“我”和“居里夫人”谈话时,安排了一个小细节——居里夫人对时间的重视,并多次描写了居里夫人看钟的动作。正是由于有了多次的铺垫,
