Abstract
Based on the seismic performance test,an aerated concrete bearing wall was modeling separately considering the relative slip between the block and the mortar by element type SPRING2 in the finite element software ABAQUS.The FEA result and the test results of the curves of aerated concrete bearing wall was com-pared.After the feasibility of simulations was verified,further parametric analyses were studied about the vari-ation of vertical normal stress,block strength,and adhesive strength,influencing the bearing capacity and de-formation of an aerated concrete wall.It can be concluded that the wall damage is shear compression failure when axial load ratio ranges from 0.15 to 0.33;changes of block strength level have obvious impact on the wall horizontal bearing capacity,and improvements of adhesive strength have little impact to wall horizontal bearing capacity,possibly reducing the horizontal displacement of ultimate load.The above researches provide necessary basis for the further experimental study and seismic calculations.关键词
