| 摘 要： | 简要回顾了结构抗震设计概念的发展状况，讨论了基于分灾模式的结构抗震设计概念；建立了基于分灾模式的结构抗震设计模型；并结合钢筋混凝土高层结构进行了分灾设计。结果表明，与普通设计相比，分灾设计在投资－效益、大震作用、最弱层层间变形指标等方面，都有不同程度的改善。

| Abstract: | The development of structural siesmic design concept is reviewed briefly. Damage reduction based structural optimization design for seismic high rise structures is studied. The basic design creteria of damage reduction based structural optimization design are given, and the formulae are derived. The numerical examples of high rise RC structures are calculated, and the results show that several structural index (such as cost profit, severe earthquake action, story drift reliability index of the weakest story) are improved by different degrees using damage reduction based design method compared with the ordinary design method. |
