Research on isolation properties of rural masonry

SHANG Shouping,SHEN Rong,HUANG Quntang (Civil Engineering College,Hunan University,Changsha 410082,China)  
In view of the present situation that general rural buildings have low earthquake resistance,a new type of seismic practical technology called steel-asphalt composite isolation pier is put forward with the characteristics of economy,simplicity and reliability.Specimens were made according to the correlation theory.The isolation experiment on a full scale rural dwelling of masonry model is carried out.The results show that:The steel of the isolation pier works in the elastic range when the peak value of the acceleration is below 0.3g.The acceleration reduction factor of isolation pier is between 0.15~0.61 when different peak values of the loading condition are input and a good damping effect is produced because a great deal of energy has been absorbed by the isolation pier,especially for high frequency loading.The details of seismic design of rural masonry structure can be reduced,and the saved funds can be used for this new steel-asphalt composite isolation pier.The total cost of the house does not increase.
