Abstract：The integrated embedded wallboard can be used for steel frame structures to further improve the assembly rate, in order to improve the installation efficiency of the integrated embedded wallboard and reduce its impact on the seismic performance of the frame structures, a flexible connection method of "hanging up and bottom sit pulp" is proposed. In order to verify the reliability of the flexible connection and to find out the effect of the integrated embedded wallboard connected by this method on the seismic performance of the steel frame structures, the mechanical performance of the single plane frame and space steel frame structures under various operating conditions was studied through low cycle loading tests and finite elements analysis. The results show that the flexible connection of "hanging up and bottom sit pulp" is reliable, and no obvious damage is seen in the "hanging up" area; the light foam plate is filled between the wallboard and the frame column, which is beneficial to energy consumption and can reduce the damage of frame structures; the influence of the integrated embedded wallboard with "hanging up and bottom sit pulp" flexible connection on the seismic performance of steel frame structures is divided into three stages, among which the small earthquake don’t participate in the anti-side effect of the main structure, when the inter-storey drift ratio is greater than 1/174, its contribution to stiffness gradually appears and there are random fluctuations; the integrated embedded wallboard under a large earthquake can be equivalent to a diagonal strut model with single brace that is "only under pressure and not pulled", considering that the base shear, plastic hinge quantity and inter-storey drift ratio are significantly increased after the action of the embedded wallboard, the randomness of its stiffness has no effect on the inter-storey drift ratio and plastic hinge, and has no effect on the base shear. The research results can provide a reference for the use of flexible connected integrated embedded wallboard for steel frame structures.
