对两层钢筋混凝土纯框架结构及外保温叠合填充墙板的框架结构进行了足尺振动台试验,对比研究了框架结构及外保温叠合填充墙板的破坏过程和破坏模式,分析了外保温叠合填充墙板对钢筋混凝土框架结构的周期、阻尼比、刚度、楼层加速度以及楼层位移的影响。研究结果表明:与钢筋混凝土纯框架结构相比,外保温叠合填充墙板框架结构阻尼比有大幅度的提高,说明外保温叠合填充墙板比一般填充墙板耗能能力强;结构的加速度放大系数随着地震烈度增加而减小,随着楼层高度的增加而增大;结构的楼层位移模式呈剪切型变形特点,层间位移角小于规范限值;填充墙体与框架主要靠钩头螺栓连接,从弹性到塑性的过程中,除了在墙板的脚部出现裂缝外,没有出现整体垮塌现象,说明填充墙体与框架的连接措施可靠,可以在地震区推广使用。
The full-scale shaking table test was carried out on the frame structure of two reinforced concrete pure frame structures and exterior insulation laminated filled wall panels. The failure process and failure mode of frame structure and external insulation laminated filled wall panels were compared. Effect of Insulating Laminated Wallboard on the Period, Damping Ratio, Stiffness, Floor Acceleration and Floor Displacement of Reinforced Concrete Frame Structures. The results show that compared with the pure reinforced concrete frame structure, the damping ratio of the frame structure of the outer thermal insulation laminated composite wallboard increases greatly, which shows that the energy-saving capability of the composite thermal insulation laminated wallboard is higher than that of the ordinary filled wallboard. The acceleration amplification factor decreases with the increase of earthquake intensity and increases with the increase of floor height. The floor displacement model of the structure is characterized by shear deformation and the displacement angle between floors is less than the specification limit. The filling wall and frame mainly rely on Hook and bolt connection, from the elastic to the plastic process, in addition to cracks in the wall of the foot, there is no overall collapse phenomenon, indicating that the connection between the filling wall and the framework of reliable measures can be used in the promotion of the earthquake area.
