［摘要］云南許多少數(shù)民族地區(qū)農(nóng)民自建房多為兩層及以下采用配原竹代替鋼筋的砌體結(jié)構(gòu)，為驗(yàn)證其抗震性能，通過對(duì)配竹筋的混凝土砌塊墻進(jìn)行低周往復(fù)荷載試驗(yàn)研究，得到其滯回性能、延性、耗能能力和剛度退化等指標(biāo)。得到墻體采用簡(jiǎn)易抗震構(gòu)造措施后，其滯回曲線呈梭形，同時(shí)其最大水平抗剪承載力也大大提高，其延性系數(shù)較小，出現(xiàn)超筋破壞，但整體來說抗震性能得到提高，說明其是一種有效的簡(jiǎn)易抗震措施，對(duì)農(nóng)村自建房的抗震有重要意義。

Abstract： Many ethnic minority areas in Yunnan province since the buildings are under the layer and using two more match the original bamboo instead of reinforced masonry structure, to verify its seismic performance, match bamboo reinforced concrete block wall low cycle loading tests were carried out to study the hysteretic performance, ductility, energy dissipation and stiffness degradation index were got. By using a simple wall seismic structural measures, the hysteretic curve of spindle shaped and the maximum horizontal shear can greatly improve the bearing capacity, the ductility coefficient is small, appear muscle failure, but overall seismic performance is improved. The result shows that it is an effective simple and easy seismic measure, which is of great significance to the seismic design of the building in the countryside.

Keywords： original bamboo wall； simple aseismic measures； low cyclic reversed load test
