| 摘 要： | 抗震规范中的标准反应谱,对不同建筑阻尼比采用同一数值(0.05),显然这与实际情况是不相符的。本文根据实测阻尼比值的收集,给出多层砌体房屋、多层及高层钢筋混凝土房屋、单层工业厂房、烟囱的阻尼比值(均值),并由此提供相应的谱值修正系数。经修正后的标准反应谱可较好地反映阻尼比对谱值的影响。

DISCUSS ON THE DAMPING OF STANDARD RESPONSE SPECTRUM IN ASEISMIC DESIGN CODE |
| |
| Abstract: | Standard response spectrum for various buildings in Aseismc design code is deter-
mined by same damping value,but it is obvious unmeet.This paper collected experiment
damping value,present average damping value and modi-ficated coefficient of response
spectrum for the multistory brick buildings,multistory and tall reinforced concrete build-
ings,single-story factory building and chimneys.The results of modification standard re-
sponse spectrum are pleased |
