蒙皮效应对蒙古包刚架抗震性能的影响

Influence of skin effect on seismic performance of yurt rigid frame

为研究蒙皮效应对蒙古包建筑抗震性能的影响,分别对添加蒙皮结构的冷弯型钢蒙古包和不添加蒙皮结构的冷弯型钢蒙古包刚架进行单点水平低周往复加载试验,通过对比2组试件的破坏程度和试验所得结果得出蒙皮效应对结构受力性能的影响.对比发现:蒙皮结构能够起到延缓结构屈服,降低结构破坏程度的作用.

In order to study the influence of skin effect on the seismic performance of yurt buildings,cold-formed steel yurt buildings with and without skin structure were designed,respectively.Single point horizontal low-cycle reciprocating loading tests were carried out on the two groups of cold-formed steel construction.According to the comparison of both the damage-rate state of the two groups of specimens and the experimental results,the skin effect on the seismic performance of the structure was obtained.The results prove that the skin structure can delay the yield of the structure,playing a role in reducing the structural damage;the addition of skin can significantly enhance the structural integrity,making the cooperative working performance of all components in the structure stronger under the action of load.
