Abstract

Abstract

To investigate the application of autoclaved aerated concrete sandwich wall panels in low-rise integrated housing， quasi-static tests were conducted on composite walls with different construction measures and openings. The failure modes， bearing capacity， deformation capacity， stiffness degradation， and displacement ductility of three types of walls were comparatively analyzed. The test results showed that the composite walls of autoclaved aerated concrete sandwich panel composite wall exhibited good seismic performance， and their failure mode was a combined bending-shear failure. The practice of integral casting of construction columns and wall panels exhibited better bearing and deformation capacities compared to the separate casting of columns and panels， with a 37.7% increase in peak bearing capacity and a 74.3% increase in the ductility coefficient. The practice of creating openings in the walls weakened the overall stiffness of the walls， significantly reducing the structural bearing and deformation capacities. Appropriately increasing the axial compression ratio could enhance the shear performance of the wall. Based on the above results， a calculation method for the shear capacity of composite walls with autoclaved aerated concrete sandwich panels under seismic action was proposed， which can provide a theoretical basis for the engineering application of autoclaved aerated concrete low-rise and mid-rise integrated houses.
