立式储罐抗震设计新方法

A new aseismic design method of stand storage tank

按照抗震设计规范的"小震不坏、中震可修、大震不倒"的抗震设计原则,结合三水准烈度,提出了储罐的地震损伤性能目标,并给出了基于地震损伤性能的抗震设计方法。通过算例表明,本文所提出的抗震设计方法,能够更加准确地考虑储罐的提离问题。

A principle for structure design against earthquake has been received,that is,structure should be un-damaged under minor earthquake,repairable under moderate earthquake and un-collapsed under large earthquake.On the basis of design principle and combing with three-level fortify principle,this paper presented an seismic damage performance objectives of tanks,a method is hereby given for aseismic design of stand steel storage tanks based on damage performance.The method for aseismic design given in this paper truly takes into account the uplifting of tanks.
