natural period meaning in Chinese
固有周期
自然周期
Examples
- Natural period of soil site
动力机器基础地基固有周期 - The stiffness of the former is less than the latter , and the natural periods of the former is longer than the latter
前者模型的刚度较后者柔，其周期较后者长。且楼板模型的选取对结构的扭转影响较大。 - The modification coefficient of the natural period will directly effect the reaction of the reinforced concrete frames under the earthquake , so
周期修正系数的取值将直接影响地震作用下钢筋混凝土框架的反应。 - ( 3 ) furthermore , the stiffness effect induced by the infill walls makes the natural period of the frames decrease , which makes the earthquake forces put on the structures increase
3 .另外,填充墙刚度效应的存在使得结构自振周期减小,从而使作用于整个建筑上的水平地震作用增大。 - I turns out to be that the position and degree of damage can not be well detected only by eigenfrequency , while only can detect if the damage has appeared . however , severe damage can be diagnosed if the modal shape and natural period are used
利用以上指标对试验构件的损伤进行识别与定位,研究结果表明,仅凭获取的固有频率不能准确判断结构构件的损伤状态及损伤位置,只能初步判断结构中是否出现损伤。
