【摘要】

：

长沙洋湖卓伯根商业综合体项目是由方钢管焊接形成的双曲面网壳结构,工程应用中各个杆件处于复杂应力状态下,文章重点研究该网壳结构在实际工程应用中的抗震性能,通过有限元分析软件对双曲面空间网壳进行足尺模拟,对结构进行模态分析,并研究了网壳结构在各方向地震作用下的动力响应及杆件受力.得出结论:结构的自振频率随模态阶数的增加分布密集,主要振型以竖向振动为主且对称分布;受力过程中产生的位移主要为竖向位移,水平方向的位移相对较小,且结构竖向位移由四周向中间逐渐变大,中心位移值最大;在地震作用下,结构两端的支撑反力最大;

Fatigue behavior of cortical bone:a review

Fatigue is a common cause of bone failure.As the main load-bearing tissue,cortical bone carries a considerable share of load in the whole bone.Under cyclic loading condition,microdamage may generates and accumulates in cortical bone,which further triggers
