摘要
为获得斜交网格筒体不同结构形式在竖向荷载作用下的侧移规律,分别建立斜交网格外框筒结构模型、仅设核心内筒的斜交网格结构模型及在核心内筒基础上增加楼板的斜交网格结构模型,并分别在3个模型顶部施加竖向荷载进行加载分析,通过改变荷载大小分析每个模型的侧移规律。研究表明:斜交网格筒体结构在竖向荷载作用下的侧移表现出特有的连续变形规律,且仅外筒、设核心筒、设楼板后对结构侧移规律的影响也不尽相同;楼板对结构侧移的限制效果较核心筒显著,且楼板较大程度地改变了结构的侧移曲线。
In order to obtain the lateral pattern of different forms of diagrid tube structures under vertical loads,the model of the external tube of diagrid tube structure,only within the core tube and set the floor on the basis of core tube of diagrid tube structure models were established respectively. Then the vertical loads were applied on the top of the three models respectively. The lateral pattern of each model by changing the load value was analyzed. Diagrid tube structures showed the characteristics of the continuous deformation law unde vertical loads,core tube and floor had different influence on the lateral pattern of diagrid tube structures. The effect of floor was remarkable and floor changed the lateral curve of the structure in a larger degree.
