地震是一种突发性强、破坏性大的严重自然灾害。地震给我国造成了巨大的人员伤亡和经济损失,同时也给我们留下了极其深刻的教训和警示,地震造成建设工程的倒塌破坏是导致人员伤亡和财产损失的主要原因,只有确定科学合理的抗震设防要求,并按抗震设防要求和抗震设计规范进行严格的设计和施工,才能保证建筑物具备一定的抗震能力,才能有效地避免、减少地震所带来的破坏和损失。综观古今中外历次破坏性地震,特别是近几年来发生的几次大地震,人员伤亡和财产损失触目惊心。得出的结论是,设防和不设防的建筑物破坏程度大
Earthquake is a kind of sudden and destructive natural disasters. The earthquake has caused tremendous casualties and economic losses to our country. At the same time, it has also left extremely profound lessons and warnings to us. The earthquake caused the collapse and collapse of construction projects as the main cause of human casualties and property losses. Only by establishing a scientific and rational Seismic fortification requirements, and according to seismic design requirements and seismic design specifications for rigorous design and construction, in order to ensure that buildings have a certain degree of seismic capacity, can effectively avoid and reduce the damage and loss caused by the earthquake. Looking at all the devastating earthquakes all over the world, especially in the aftermath of several major earthquakes in recent years, it has shocked people’s lives and property losses. It came to the conclusion that fortified and undefended buildings were devastating
