摘要
针对立式钢制储罐在强烈地震作用下会产生不同程度的损伤的特点,遵循抗震设计规范的"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。所提出抗震设计方法,更加准确地考虑了储罐的提离问题。
As standing steel storage tanks will bring about different degree of damage under intensive earthquake.A principle for structural earthquake resistant design has been received,that is,structure should be un-damaged under minor earthquake,repaired under moderate earthquake and un-collapsed under large earthquake.On the basis of design principle and combing with three-level fortifing intensity,a seismic damage performance objective of tanks is presented,a method is hereby given for seismic design of the standing steel storage tanks based on damage performance.The seismic design method given in this paper truly takes into account the uplifting of the standing steel storage tanks.
