自密实混凝土保温复合剪力墙受力性能试验研究

Experimental Research on Mechanical Properties of Self-compacting Concrete Insulation Composite Shearing Wall

通过4片自密实混凝土保温复合剪力墙受力性能的试验研究,其中第一组为平面外受弯试件,第二组为受剪试件,研究垂直插筋和水平斜插筋对自密实混凝土保温复合剪力墙受力性能的影响,对比分析了自密实混凝土保温复合剪力墙的破坏特征、承载力、刚度及插筋的受力性能等。试验结果表明,垂直插筋和水平斜插形式下的自密实混凝土保温复合剪力墙均具有良好的受力性能,能满足承载力和刚度要求。与水平斜插筋相比,垂直插筋能更好地协调和约束两侧自密实混凝土的变形,使试件具有更高的承载能力和刚度。

In order to research the effect of vertical inserted-steel and horizontal inserted-steel on mechanical behavior of self-compacting concrete insulation composite shearing wall, the shearing walls are tested based on the experiment and analysis of 2 groups of 4 specimens, in which the first group is bending specimens and the second group is shearing specimens. And the damage characteristic, bearing capacity, rigidity and stress of inserted-steel of self- compacting concrete insulation composite shearing wall are compared and analyzed. The experimental results show that the self-compacting concrete insulation composite shearing wall with two inserted steel forms all have good mechanical behavior to meet the requirements for bearing capacity and rigidity. Compared with the specimens with horizontal insertedsteel, vertical inserted-steel can better coordinate the deformation of two sides of self-compacting concrete, which makes specimens have higher bearing capacity and rigidity.
