［摘要］蒙古包的豎向荷載主要來自雪荷載。在參考蒙古包原型尺寸的基礎(chǔ)上，利用建模軟件SOLID WORKS及ABAQUS構(gòu)建了蒙古包結(jié)構(gòu)骨架模型，研究了傳統(tǒng)蒙古包結(jié)構(gòu)在里圍繩作用下，結(jié)構(gòu)各部件在滿布雪荷載和半分布雪荷載時(shí)的受力機(jī)理與受力形態(tài)。研究結(jié)果表明，傳統(tǒng)蒙古包結(jié)構(gòu)在雪荷載作用下，套腦起到了烏尼的支座效果，在向下位移過程中與烏尼相互支撐，達(dá)到平衡狀態(tài)；烏尼呈現(xiàn)出簡支梁均布荷載作用下受彎的特點(diǎn)；哈那均勻地分散了上部結(jié)構(gòu)傳遞的荷載；里圍繩可阻止哈那上部外張，起到了維護(hù)結(jié)構(gòu)整體性的重要作用。

Abstract:The vertical load of Mongolia yurt mainly comes from snow load. Based on the reference of the original size of the Mongolian yurt, the framework model of the Mongolian yurt structure was constructed by using the modeling software SOLID WORKS and ABAQUS. The mechanical behavior and form of the components of the traditional Mongolian yurt structure under the action of the inner ring rope under the full snow load distribution and the half snow load distribution were studied. The research results show that under the action of snow load, Taonao of traditional Mongolian yurt structure has the bearing effect of Unni, and it supports each other with Unni in the process of downward displacement to reach the balance state; Unni presents the bending characteristics under the uniform load of simply supported beam; Hana evenly disperses the load transmitted by the upper structure; the inner ring rope can prevent the upper part of Hana from stretching out and maintain the important role of construction integrity.
Keywords:traditional Mongolian yurt structure; mechanical behavior; full snow load distribution; half snow load distribution
