Full scale shaking table tests on frame structure with new SIP filling wallboard

Full scale shaking table tests on a two-layer reinforced concrete frame without wallboard and with a new type of SIP filling wall plate were conducted, in order to study the failure process and failure modes of the reinforced concrete frame and wallboard. The influences on the vibration period, damping ratio and stiffness of the reinforced concrete frame because of the addition of the new SIP wallboard were investigated. From the results, it is found that compared with the reinforced concrete frame without wallboard, the lateral stiffness increases 2.42 times for each layer and the damping ratio increases 1.87 times in the frame structure with the new SIP filling wall plate. The damping ratio is 5.891%, more than 5%, and its energy dissipation ability is better than that of the ordinary filling wall. The acceleration amplification coefficient of the structure decreases as the earthquake intensity increases and it increases as the floor height increases. The floor displacement mode of the structure belongs to the type of shear deformation and the interlayer displacement angle is less than the standard limit. From elastic to plastic states, beside the appearance of cracks at the root of the pillars and on the wall, there is no overall collapse phenomenon. The results indicate that the connection measures between the wallboard and the frame are reliable and these kinds of connection measures can be used widely in the earthquake region.
