本文从汶川地震引入,介绍了地震给工程结构带来的破坏及其原因。正因为地震给人类带来的巨大伤害,在人类无力改变自然灾害的情况下,人类只能想方设法将灾害带来的损失降至最低。从而阐述了抗震的概念设计,结构的抗震设计以及抗震的各种措施等,以达到抗震设防的目的。 This paper introduces from the Wenchuan earthquake, introduces the damage caused by the earthquake to the engineering structure and its causes. It is precisely because of the tremendous damage caused by the earthquake to humankind that mankind can only find ways to minimize the losses caused by disasters in the case of man’s inability to change natural disasters. Thus, the conceptual design of seismic design, the aseismic design of structures and various measures of earthquake resistance are expounded in order to achieve the purpose of seismic fortification.
