概述第五代《中国地震动参数区划图》即将颁布实施,全国部分区域抗震设防烈度将有所改变。第一,全国范围建筑都应进行抗震设计,最低的抗震设防烈度为Ⅵ度,个别原不设防地区甚至调到Ⅶ度(0.10g);第二,部分Ⅵ度区调整到Ⅶ度(0.10g),少数区域调整到Ⅶ度半(0.15g),个别区域调至Ⅷ度(0.20g);第三,部分Ⅶ度(0.10g)调到Ⅶ度半(0.15g),少数调到Ⅷ度(0.20g);第四,部分Ⅶ度半(0.15g)调到Ⅷ度(0.20g),个别区域降低到Ⅶ度(0.10g);第五,部分Ⅷ度(0.20g)调到Ⅷ度半
Overview The fifth generation “China Earthquake Zoning Plan” will be promulgated and implemented in some areas of the country’s seismic fortification intensity will change. First, seismic design should be carried out across the country. The minimum seismic fortification intensity is Ⅵ degree, and even some unprotected areas are even transferred to Ⅶ degree (0.10g). Second, partial Ⅵ degree area is adjusted to Ⅶ degree (0.10g ), A few areas adjusted to Ⅶ degree and a half (0.15g), some areas adjusted to Ⅷ degree (0.20g); third, part Ⅶ degree (0.10g) transferred to Ⅶ degree and a half (0.15g), a few transferred to Ⅷ (0.20g); Fourth, part of the VII degree and a half (0.15g) transferred to Ⅷ degree (0.20g), individual areas reduced to VII degrees (0.10g); half
