RESEARCH AND ANALYSIS OF AXIAL COMPRESSIVE PERFORMANCE OF LIGHT STEEL FOAM CONCRETE COMPOSITE WALL
This paper studies the axial compressive performance of light steel lightweight concrete combination wall,the finite element model of which is established by ABAQUS software.The numerical simulation results are compared with the experimental results,showing a good agreement with each other.On this basis,the effectiveness of steel content and lightweight concrete strength on the axial compressive capacity of lightweight steel and light-weight concrete combination wall is analyzed.The results show that with the increase of steel content,the peak load also increases,and the steel content plays an important role in the axial compressive load capacity and stiffness of the combined wall.With the increase of foam concrete strength,the stiffness and axial compressive load capacity of the combined wall increase significantly,whereas the ductility coefficient decreases.
