Research on bending performance of sand aerated concrete composite exterior wall panels
Through finite element analysis,determine the influence characteristics of the elastic modulus of the insulation layer and the arrangement of tie members on the outer bearing capacity and stiffness of the wall panel,the combination degree of the test pieces,and the calculation methods for the bearing capacity,stiffness,and cracking moment of the wall panel.The results show that the bonding effect between the inner and outer leaf sand aerated wall panels and the intermediate insulation layer can signifi-cantly improve the surface bearing capacity and stiffness of the sand aerated composite exterior wall panels.The increase in the number of tie pieces has a relatively small impact on the load-bearing capacity and stiffness of sand aerated composite exterior wall panels.The combination degree of sand aerated composite exterior wall panels is relatively low,and the surface bearing capac-ity and stiffness are calculated according to the non combination stress mode.The calculation method for the cracking moment of ordinary reinforced concrete slabs is in good agreement with the experimental values,and can be applied to the calculation of the cracking moment of such sand aerated composite exterior wall panels.
