Experimental Study Of Mechniacal Performance And Seismic Performance Of Rammed-earth Wall

The raw-soil structure,which is still used in our country,is one of the forms of the village and town building.Raw-soil structure originates form nature and harmony with nature.As a kind of ancient regional building,the raw-soil building has attracted wide attention from its global scholars because of its low energy consumption 、excellent thermal performance 、 green and pollution-free.However,the raw-soil building has its own drawbacks,the wall with traditional process makes the seismic behavior of raw-soil structure poor,the durability is bad.Raw-soil structure is severely affected by the earthquake.In order to develop raw-soil building,the research of the Raw-soil building is essential,and as our precious cultural heritage.We should carry forward the advantages of raw-soil building,research tradition and agree with present.In this paper,the types and building habits of the Raw-soil structure is investigated.Refer to the research status of raw-soil building at home and abroad.Experimental studies are performed on the bearing performance of rammed-earth wall of raw-soil structure.The compressive and monotonic loading tests of rammed-earth walls are carried out.The experiments of rammed-earth walls that use different proportions and tamping techniques are studies,the bearing capacity and deformation behavior of rammed earth walls under monotonic horizontal load are analyzed.Next experimental study on seismic performance of rammed-earth walls are carried out,vertical loading and low cycle reversed horizontal loading are carried out on specimen aimed to study the failure process,failure mode,hysteretic curve and skeleton curve feature.The horizontal bearing capacity and deformation capacity of the wall also are studied.Finally,it verities the possibility of building a two layer house in 7 degree and 8 degree by comparing the theoretical and experimental analysis.
