Research on the bearing capacity of foam concrete wall materials in green buildings Available to Purchase

This study fabricated a combined wall with the help of a lightweight steel structural wall skeleton and foam concrete (FC) and designed four sets of strain experiments for walls with different FC densities and steel contents. In the displacement results, the higher the density of FC, the higher the load-bearing capacity. When the density of FC is 1000 and 1600 kg/m³, the wall will lose its load-carrying capacity after a maximum load of 80 and 90 kN, respectively. The greater the axial compression ratio of the sample, the greater the shear capacity of the combined wall. When the displacement distance is 30 mm, the maximum load is 162, 110, 94 and 85 kN when the shear span ratio is 1.0, 2.0, 3.0 and 4.0, respectively, and the load-carrying capacity decreases with the increase in the shear span ratio. Moreover, compared with the shear span ratio of 1.0, the load-carrying capacity decreases by 23, 41 and 51% successively. The maximum loads of the combined walls are 88, 79, 81 and 62 kN when the densities are 800, 1000, 1200 and 1600 kg/m³, respectively, and 75, 80, 81, 94 and 101 kN when the steel content ratios are 0.5, 1.0, 1.5, 2.0 and 2.5%, respectively.
