| 摘 要： | 利用Solidworks及ABAQUS软件建立了传统蒙古包的有限元模型,探讨了传统蒙古包在地震作用下的受力机理。结果表明:在设防烈度为8度、最大基本加速度为0.30g的地震作用下,结构构件并未出现破坏,结构整体性较好;传统蒙古包结构上部为主要的耗能部位,乌尼与上部的套脑通过沿地震波方向的晃动释放能量;结构的易破坏处为乌尼杆、里围绳以及哈那与里围绳连接处、乌尼与套脑连接处。

| Abstract: | The force mechanism of the traditional yurt under the earthquake is discussed by using the commercial software of Solidworks and ABAQUS to establish a traditional yurt finite element model.Results show that the structural components do not appear to be damaged,and the structural integrity is better under the effect of the earthquake with the maximum basic acceleration of 0.30 g at 8 degrees fortification,that the upper part of the traditional yurt is the main energy consuming part,and Unni as well as the upper Taonao cover releases energy by shaking along the seismic wave direction.It is found that the vulnerable parts of the structure are the Unni rod,the inner encircling rope and the Hana,which came into contact with the inner encirclement rope,and the junction of Unni and the sleeve of the Taonao. |
