Abstract

Abstract

A group of 1/2 scale model of ecological composite wall with straw mud billet block was tested under lowfrequency cyclic loading．The seismic performance of the specimen, such as failure mode, shearing capacity, deformation, ductility, energy dissipation and so on, was mainly researched．And the seismic performancecomparative analysis of the ecological composite wall with different shear span ratio was made base on the preexperimental study．A non-linear finite element model was established to analyze its failure mode and shear capacitywith different shear span ratio．The results showed that with the increase of the shear span ratio, the shear capacity ofwall was decreased significantly, but deformation capacity and energy dissipation capacity were increased．Based onreasonable failure mode( shear type failure) the rational value ranges( 1．0 1．8 ) about shear span ratio were putforward, and the ultimate shearing capacity modified formula for eco-composite wall based on different shear spanratio was proposed．The error of calculation results was small is compared with test value, which satisfied theengineering precision．
