At present,the research ofdeepbeam infilledsteelframe abroad is atthevery initial China,this research isnearly thispaper,low—cycle loading testmethod is employed,considering nonlinear factors ofdifferentmaterials and height—widthratios,deep beams from threekinds ofmaterials(steel,reinforced concrete posite)are each kind ofmaterial,two deepbeams ofdifferent sizesare parative test ofpure steelframe,seven model plished intotal. For eachspecimen,the hysteretic loops,distribution of stressand deformation behaviour under low—cycle loading arerepresented,the principle ofenergy dissipation isanalyzed,and theductilityandstrengthdegeneration onexperiment results,the affects ofmaterialandheight-width ratioofdeepbeams areconcluded. The experiment data demonstrated paring topure steelframe,deep beam infilledsteelframe structureapparently enhanced the intialstiffness and ultimatebearing capacity,solved theproblem ofstiffness insufficiency changing theheight towidth aspect ratio,the modulation ofstiffness could transitionbetween pure frame andframe-shear wallprovided urateand economical structuralformfor engineering design. Comparing topureframe,t
