RESEARCH ON STRUCTURE OF COMPOUNDED RAW SOIL WALL'S SEISMIC PERFORMANCE AND DESIGN METHODS

生土复合墙结构是一种生态、节能、减振、装配整体式的村镇住宅新型结构体系。结合试验结果,对内填泥坯生土复合墙体在竖向及水平荷载作用下的破坏过程及受力特征进行研究,并与内填加气混凝土砌块标准墙体的破坏特点进行综合对比分析,探讨了生土复合墙体的承载力、延性、耗能等抗震性能。在此基础上提出了内填泥坯生土复合墙结构的计算模型及抗震构造措施。试验及试点工程研究表明:内填泥坯砌块生土复合墙结构具有较好的抗震性能;同时,就地取材,制作简便,节能环保,适合低层村镇住宅结构的需求。

The structure of compounded raw soil wall is a ecological, energy-saving and assembled monolithic structure,which is a new system for village residential building. Based on previous research achievements and experiment results, it was analyzed the failure process and force characteristics of composite-wall structure with mud blocks under veItical and horizontal loads. The comparative analysis was done for the damage characteristics of the compounded raw soil wall and the standard wall with aerated concrete blocks, it was also discussed the wall bearing capacity, ductility, energy dissipation and seismic performance. On the basis of this, the calculating model and seismic tectonic measure of composite-wall structure with mud blocks were proposed. Test research and pilot project show that the structure of compounded raw soil wall with mud blocks is a structure with good seismic behaviour. At the same time, the structure has the characteristics of using local materials, simple production, energy efficiency and environmental protection. It is suitable for low-rise village and town buildings.
