【摘要】 建立了立式储罐的地震损伤模型,利用耗能及变形计算的简化公式,计算了工程上常用的8种浮顶罐的损伤指数,给出了应用于立式储罐的损伤指数范围.在此基础上,提出了立式储罐基于损伤性能的抗震设计准则:对于小震不坏的结构,采用现行抗震规范的强度验算形式;对于大震不倒的结构,采用考虑损伤性能的验算形式.算例结果表明,基于损伤性能的立式储罐抗震设计方法能够更加合理地评价储罐的破坏程度.更多还原

【Abstract】 In this paper, a seismic damage model is set up, computation for base distortion and energy is used to calculate eight kinds of tanks damage index, and the damage index scope is given. On the basis of this, an aseismic design method for vertical steel tanks based on damage performance is presented. Under minor earthquakes, current seismic standards is employed to verify intensity and under large earthquakes, damage performance design method is used.更多还原
