中美石油化工工艺管道抗震规范的对比研究

COMPARATIVE STUDY BETWEEN CHINESE AND AMERICAN SEISMIC STANDARDS FOR NON-BURIED PIPES IN PETROCHEMICAL INDUSTRY

抗震设计已经成为现代化工程设计尤其是海外工程项目非常重要的组成部分。对于海外项目,熟悉并了解国外规范尤其是美国规范是抗震设计的基本前提。主要通过对现行石油化工非埋地金属管道抗震标准SH/T3039与美国规范ASCE7和UBC1997中关于管道抗震设防目标、管道抗震验算条件、地震系数计算、基本荷载组合中荷载分项系数取值几个核心方面的比较分析,得出中美管道抗震标准的异同,以此来加深对美国石油化工非埋地金属管道抗震规范的了解和掌握。

Seismic design has become an important part of modern engineering design especially in overseas projects.Mastering foreign standards especially the American standards is the basic premise of the seismic design for overseas projects.This paper compares the current Chinese standard SH/T 3039 with the American standards ASCE 7 and UBC 1997 concerning the seismic design of non-buried metal pipes for petrochemical industry from the aspects of seismic fortification goals,seismic checking conditions,seismic coefficient calculation,and the selection of load partial coefficient in basic load combination,and points out their similarities and differences,so as to deepen the understanding and mastery of the American standards concerning the seismic design of non-buried metal pipe for petrochemical industry.
