This paper uses of the actual mechanics form , cantilever bending stiffness is adopted in the mega structure , however shearing stiffness in the sub structure . based on the complex mode theory , this paper gains the expression of dynamical response of the system based the model of municipal no . l building of tokyo city and analyses the affection of the main parameters ( stiffness and damping ) on the two configurations ( sustaining type and hang type ) . the results indicate that the rational stiffness of the sub structure can control the deformation of the mega structure perfectly , but the acceleration of the sub structure increases at the same time 本文采用了更接近实际的力学模型,主结构采用弯曲刚度,子结构采用剪切刚度,利用随机振动复模态理论,推导了巨型框架减振结构的动力响应表达式,并以日本东京市政一号楼为基本模型,讨论了巨型框架减振结构两种结构形式(座承式和悬挂式)的主要参数(刚度和阻尼)对减振效果的影响,结果表明:与普通巨型框架结构相比,减振结构通过合理选择子结构刚度,可以较好的控制主结构在顺风向脉动风作用下的位移响应,从而提高结构的安全性,但与此同时,子结构自身的加速度响应也有了一定程度的提高。
The obtained results do not support a major gene for body mass index in chinese , the discrepancies between our study and previous studies may result from ethnic difference between chinese and other populations ; the general model provides the best fit to the data , while the environmental model is the second parsimonious model , perhaps due to complex mode of body mass index inheritance ; a moderate heritability estimate is found for body mass index ( h2 = 0 . 313 ) , lower than that of other populations , this is presumably due to the fact that aside from the influence of genetic bases , body mass index is strongly influenced by environmental factors and that there is a low proportion of obese individuals in samples ( only 4 . 1 % individuals have body mass index > 30 ) 分离分析的结果表明, ( 1 )体重指数不存在主基因分离,不同于在其他非中国人群中检测的结果,说明存在种群差异性; ( 2 )一般模型提供了最合适模型,环境模型是次之的严格模型,可能由于体重指数遗传模式的复杂性所致; ( 3 )中国人群中体重指数具有适中的遗传率( h ~ 2 = 0 . 313 ) ,低于其他人群中的结果,这是由于体重指数除了受遗传因素影响外还受环境因素影响及样本中低比例的肥胖个体( 4 . 1的个体bmi 30 )的原因。
