中文摘要:
      作为结构抗震设计的发展方向,近年来基于功能的结构抗震设计思想引起了地震工程界的广泛重视,并取得了迅速发展,其基本思想就是在充分考虑结构抗震设计中的不确定性的情况下,采用基于“投资-效益”准则和强调结构“个性”的设计,本文讨论了基于可靠度和功能的结构抗震优化设计思想,建立了钢筋混凝土呆-剪力墙结构 抗震优化设计模型,给出了结构可靠度的近似计算方法,最后计算了钢筋混凝土框架-剪力墙的算例。
英文摘要:
      As the development tendency for structural seismic design, the concept of performance based seismic design has drawn more and more attentions in the field of earthquake engineering and undergone a lot of developments in recent years. The basic idea of performance based seismic design is the optimization design based on cost-effectiveness criteria, considering the structural "individuality" and the uncertainties in the seismic design. The theory and methodology of reliability and performance based optimization design for seismic high-rise structures are studied in the present paper. The optimization design formula for seismic RC frame-wall structures is established, and the simplified approximate approach to calculate structural reliability is proposed. Finally, the seismic optimization design for high-rise RC frame-wall structure is carried out.
