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

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 vertical 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．
