本文以具有3个塔楼的厦门东方时代广场为分析对象，采用国际通用有限元分析软件sap2000进行结构建模和分析，考虑双向地震动输入，研究结构的振动特性，分析底盘与塔楼刚度比对结构的影响以及多塔之间的扭转效应和平扭耦联作用，对比风荷载和地震作用下塔楼在两个结构主轴方向的层间位移、顶点位移以及塔楼底层的变形，分析地震作用下转换层楼板的应力分布特点及主要竖向构件的正应力和剪应力分布特点。 | | 3. | From above analysis , the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big , the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers . the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement , but also make large influences on the stress of transfer plate and near floors , thus it is necessary to strengthen those floors
通过上述分析，得出以下主要结论：多塔楼结构存在频率密集现象，各振型间耦联效应明显，地震作用计算应采用cqc组合原则而不能简单地采用srss组合原则；非对称多塔结构的振型中，扭转作用明显，平扭耦联效应值得考虑；裙楼刚度对整体结构的抗震性能影响很大，非对称多塔结构宜控制裙楼与塔楼刚度比在适宜的范围；非对称多塔易导致平面刚度分布不均匀，结构扭转效应不仅在竖向抗侧构件中引起较大的扭转内力，对转换层楼板应力有较大的影响，且延续至相邻楼层，对相应楼层均应采取相应的加强措施。 | | 4. | We used this system to check some representative images on the web , we could got a conclusion that most encode images is easy to decode . without right theory they can ’ t build a robust encoded image . and through thorough experiments by this platform i have concluded such points : single alpha encoded is useless , we must encode all characters as whole ; confusion points are useless , we must use confusion lines which look like stroke ; enlarge base of character such as chinese character , not only digital number and alpha
并且通过该平台的广泛实验总结出增强图片加密强度的几个要点:只加强单个字的加密是不行的,必须把整体作为加密对象,增强字与字之间的干扰;单纯的噪点作用不大,具有笔画特征的干扰线作用更大;应该引入一些随机变量,比如每副图片的字个数随机,加密方法随机选择;增大可选词汇的基数,可以考虑使用汉字,而不单纯是数字和英文。 |
