摘要:

研究内嵌式预制混凝土墙板对装配式剪力墙结构附加刚度的作用机理,分析墙板对结构刚度的影响规律,共建立26个工况进行分析。结果表明三面出筋连接形式的内嵌墙板会显著增加装配式剪力墙结构的抗侧刚度,其机理与填充墙附加刚度机理类似;墙板附加刚度大小主要由自身尺寸决定,墙板水平长度越长,附加刚度越大,但附加刚度随墙板水平长度增加而增长的速率是非线性的;钢筋间距与直径不是影响墙板附加刚度的主要因素。

Abstract:

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.
