Abstract:
In order to study the lateral stiffness and bearing capacity of autoclaved aerated concrete(ALC)panel and the crack resistance of wall and decorative layer under horizontal load, the hysteretic tests of three ALC panel-articulated steel frames were carried out by using three connection modes of pipe clamp, U-shaped clamp and right-angle steel parts and different finishing methods. The results show that the hysteresis curves of the walls of the three connection modes are all seriously pinched. It means that the energy dissipation capacity of the ALC wall is poor. The stiffness of the connector has a significant effect on the mechanical performance of the ALC wallboard. The greater the stiffness of the connector, the greater the lateral stiffness and bearing capacity of the wall, but the more serious the wall cracking is. The lateral bearing capacity of the right-angle steel wall is the largest, which is 14.9% and 131.4% higher than that of the pipe wall and the U-shaped wall, respectively. The lateral stiffness of the right-angle steel wall is close to that of the pipe wall, which is 52.1% higher than that of the U-shaped wall. In terms of crack resistance of wallboard, U-shaped card wall is the best, and pipe card wall is the worst. When the interlayer displacement angle is 1/2 000-1/1 000, the crack occurs in the decorative layer at the joint position between the wall and the steel frame of the three connection modes, which is the weak position of the crack resistance of the decorative layer. The anti-cracking performance of the veneer is greatly affected by the stitching method, and the elastic material can significantly improve the anti-cracking performance of the veneer. The surface of the joint between the wallboard and the wallboard has good crack resistance, which cracks when the interlayer displacement angle of the pipe clamp wall and the U-shaped clamp wall is 1/50 and 1/60 respectively. However, no crack occurs for the right-angle steel specimen even though the inter-story displacement angle reaches 1/33.
