【摘要】：通过分析传统蒙古包结构各组成构件之间的实际接触,确定其在有限元软件ABAQUS中的类比接触,完成模型建立。然后通过模拟传统蒙古包结构在竖向荷载作用下各杆件及重要连接节点的受力形态及特点,并与结构在无里围绳作用时作对比。结果表明,传统蒙古包结构上部可视为由简支梁结构组成的棚顶,下部是由里围绳约环向束下S型曲杆相互铰接而成的网状结构。通过将竖向荷载均匀分布至杆件,由杆件之间相互约束和变形传递荷载并保持稳定,同时验证了里围绳对结构的必要性,完成对传统蒙古包结构合理性的论证。
[Abstract]:Through the analysis of the actual contact between the components of the traditional Mongolian yurts structure, the analogical contact in the finite element software ABAQUS is determined. The model is set up. Then, by simulating the behavior and characteristics of the traditional yurts structure under vertical load, the structure is compared with the structure under the action of no inner girth rope. The upper part of the traditional yurts structure can be regarded as the roof composed of simply supported beam structure, and the lower part is the net structure which is made up of the S-shaped curved bar hinged under the circumferential bundle of the inner circumference rope. The vertical load is uniformly distributed to the members. The load transfer between the members is controlled and deformed and the load is stable. At the same time, the necessity of the inner girth pair structure is verified, and the rationality of the traditional yurts structure is demonstrated.
