The influence of autoclaved aerated concrete panels on the mechanical properties of fabricated steel frames was experimentally investigated. Two fabricated steel frame specimens, which were with and without autoclaved aerated concrete panels, respectively, were tested under reversed cyclic loads. They were 1/2-scale, two-storey, and single-bay steel frames that were assembled by bolted beam-height adjustable steel beam-to-column connections. The effect of autoclaved aerated concrete panel dimensions on the mechanical behavior of infilled frames was also parametrically analyzed with the proposed numerical models which were verified on the basis of experimental data. The results indicate that the fabricated steel frames, assembled by beam-height adjustable connections, could behave in a ductile manner with sufficient stiffness and strength under cyclic loads; compared with bare steel frames, autoclaved aerated concrete panels could postpone the failure of structures and increase their initial stiffness, peak load, and energy dissipation capacity; moreover, the geometric details of autoclaved aerated concrete panels could significantly change the mechanical properties of infilled steel frames.

Theoretical Results

Autoclaved aerated concrete panels (AACP) are lightweight elements in civil engineering design. In this paper, experiments and numerical analyses were conducted to study the flexural behavior of an enclosure system that consisted of AACPs and a decorative plate. A full-scale test was conducted to investigate the behavior of the enclosure system under wind suction. Load–deflection curves and load–strain relationships under different wind pressures were recorded and discussed. The effects of thickness, reinforcement ratio, and strength grade on the flexural behavior of AACPs were numerically investigated. Based on the numerical results, we found that the flexural behavior of AACPs can be improved by increasing the thickness or the reinforcement ratio. A comparison of finite element and theoretical results calculated using American and Chinese design formulae was conducted, and the results indicated the existing design formulae can conservatively estimate the major mechanical indices of AACPs.
