Abstract
En 中文
This study investigates the seismic performance of a novel prefabricated Autoclaved Aerated Concrete (AAC) panel-based structural system for low-rise buildings. Six full-scale AAC shear-wall specimens with different configurations were fabricated. Low-cycle cyclic loading tests were conducted under constant axial pressure. The tests systematically evaluated the effects of edge restraints, wall thickness, and assembly method on hysteretic behavior, failure modes, and energy-dissipation capacity. Cast-in-place side columns produced marked increases in load-bearing capacity, ductility, and overall integrity. The 200 mm-thick specimens exhibited higher bearing capacity than the 240 mm-thick specimens. These results indicate that the distribution of shear and bending deformations can be optimized. Reducing the stiffness of the wall panels and side columns facilitates this balance and improves structural performance. Vertically spliced walls exhibited significantly better seismic performance than horizontally spliced walls. A formula for the shear capacity of AAC shear walls with structural columns is proposed, derived from tests and theoretical analysis. The calculated capacities are in good agreement with the experimental results. This work provides a theoretical and empirical basis for the seismic design and practical application of prefabricated AAC shear walls.
