摘要
我国是世界上地震灾害最严重的国家之一,自1959年起第一部抗震规范颁布至今,已有近60年的历史。从主要沿袭苏联标准到自主试验探究再到主动与国际接轨、逐步提高抗震设防水准,此过程中我国的抗震规范不断完善。本文主要对《建筑抗震设计规范》(GB50011-2010)和《Eurocode 8》进行对比分析,同时考虑材料基本性能、分项系数、荷载组合系数、抗震设防目标等基本原则;场地类别和设计用反应谱取值、底部剪力法等地震作用计算;内力调整、抗震构件等具体设计方法等。此外,利用算例对比两本规范在结构抗震设计时的安全性验算、内力计算和配筋量等方面的差异。
China is one of the countries with the most serious earthquake disasters in the world.Since the first seismic design code was promulgated in 1959,Chinese seismic codes are continuously improving.This paper mainly compares the"Code for Seismic Design of Buildings"(GB 50011—2010)and"Eurocode 8".Including:basic principles such as material properties,safety factors,seismic design procedures;action calculation such as site category,response spectrum and base shear method;specific component design methods such as internal force adjustment.In addition,an example is employed to compare safety,internal force calculation and reinforcement ratio of the two codes in the seismic design of a reinforced concrete structure.
