Study on the Influence of Embedded Precast Concrete Wallboard on the Stiffness of Assembled Shear Wall Structure

In order to clarify the mechanism and influence of the additional stiffness of the embedded precast concrete wallboard to the assembled shear wall structure, 26 schemes were established for analysis. The results show that the embedded wallboard with exposing steel bars on three sides will significantly increase the lateral stiffness of the assembled shear wall structure, and its mechanism is similar to that of the filler wall. The additional stiffness of the wallboard is mainly determined by its size. The longer the horizontal length of the wallboard is, the greater the additional stiffness is. The increase rate of the additional stiffness with the increase of the horizontal length of the wallboard is nonlinear. The spacing and diameter of the steel bars are not the main factors to affect the additional stiffness.
