    摘要
  • 摘要: 通过2块标准墙板试件的四点弯曲加载试验，研究了轻钢龙骨混凝土组合墙板（简称SC墙板）的抗弯性能以及竖龙骨间距对墙板抗弯性能的影响。试验结果表明：墙板的抗弯破坏形态均以竖龙骨屈曲破坏为主，承载力由正常使用极限状态控制，竖龙骨间距对SC墙板的承载力有较大影响；采用ABAQUS软件建立了SC墙板的有限元模型，对比试验结果验证了模型的可靠性，并进行了相关参数分析。分析结果表明：龙骨厚度及腹板高度、保温材料类型、空气层以及剪力钉的间距对SC墙板的抗弯强度影响较为明显；取消空气层可大幅提高墙板的抗弯承载力；而采用泡沫混凝土作为保温材料可以有效限制竖龙骨的变形，提高墙板的抗弯承载力和耗能能力。
    Abstract: Two standard wall panel units were tested under bending load to study the flexural behavior of light-gauge steel stud concrete composite wall panel (SC wall panel) and the stud spacing was considered as an experimental parameter. The experimental results showed that the failure of SC wall panels were mainly caused by the buckling of the stud and the bearing capacity of the SC wall panel was controlled by the serviceability limit state. Moreover, stud spacing had a great influence on the bearing capacity of the SC wall panels. Then, finite element models of SC wall panels were established with ABAQUS and a parameter analysis was conducted. The results showed that the flexural behavior of SC wall panels was mainly influenced by the thickness of the keel, the height of the web, the type of the thermal insulation material, the air layer and the spacing of the shear studs. The flexural capacity of the composite wall panels could be greatly improved when the air layer was cancelled. Besides, replacing the rock wool with foam concrete could effectively restrict the deformation of the stud and improve the flexural capacity and energy dissipation capacity of the SC wall panels.
