摘　　要：为研究水平荷载作用下蒸压加气混凝土(ALC)板的抗侧刚度、承载力以及墙体与装饰层的抗裂性能,采用管卡、U型卡和直角钢件3种连接方式和不同饰面做法对三榀ALC墙板-铰接钢框架进行了滞回试验。结果表明:3种连接方式的墙体滞回曲线均捏缩严重,即ALC墙体自身耗能能力较差;连接件的刚度对于ALC墙板的受力性能影响显著,连接件刚度越大,墙体抗侧刚度和承载力越大,但墙体开裂情况也越严重,其中直角钢件墙体抗侧承载力最大,分别比管卡墙体和U型卡墙体高14.9%和131.4%,直角钢件墙体与管卡墙体抗侧刚度接近,比U型卡墙体高52.1%;墙板抗裂性能方面,U型卡墙体最好,管卡墙体最差;3种连接方式的墙体与钢框架接缝位置饰面层在层间位移角为1/2 000~1/1 000时即出现开裂,该处为饰面抗裂的薄弱位置;饰面勾缝处理方法对饰面抗裂性能影响较大,弹性材料可显著改善饰面的抗裂性能;墙板与墙板接缝处的饰面抗裂性能良好,管卡墙体与U型卡墙体分别在层间位移角为1/50和1/60时板缝位置饰面层出现开裂,而直角钢件试件层间位移角达到1/33时板缝处饰面仍未开裂。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 panelarticulated steel frames were carried out by using three connection modes of pipe clamp,U-shaped clamp and rightangle 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 rightangle 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 1/2000-1/1000,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.
