钢板混凝土剪力墙广泛用于超高层混合结构,钢板与混凝土之间的组合作用,使其有着高的承载力、良好的刚度和延性,钢板与混凝土之间抗剪连接件设计是实现这种组合作用的关键保障,目前设计标准中尚未有针对这种平面构件连接件的定量计算方法。在总结相关标准及文献的基础上,根据钢板混凝土剪力墙的受力特点,提出了钢板与混凝土的正截面和斜截面的界面剪力的计算方法,进而得到总界面剪力,据此来计算连接件(栓钉)的需求量,在界面上分区布置;探讨了栓钉布置方式和钢板局部稳定性对栓钉间距的影响,发现梅花形布置能适当增加栓钉间距,给出了不同布置方式并考虑钢板局部稳定时栓钉间距与钢板厚度比的最大值。最后,以一实际混合结构工程为例,探讨了上述方法的适用性,可供设计参考。
Steel plate concrete shear wall is widely used in super high-rise mixed structure, the combination of steel plate and concrete, so that it has high bearing capacity, good stiffness and ductility, shear connection between steel plate and concrete design is to achieve this The key guarantee of the combination is that there is no quantitative calculation method for this kind of planar member connector in the current design standards. On the basis of summarizing relevant standards and literature, according to the force characteristics of steel plate concrete shear wall, the calculation method of the interfacial shear between the normal section and the oblique section of steel plate and concrete is proposed, and then the total interfacial shear force is obtained Calculate the demand of connecting pieces (studs), and arrange them on the interface. The influence of the arrangement of studs and the local stability of studs on the studs’ spacing is discussed. It is found that the plum pattern arrangement can increase the stud spacing appropriately, Arrangement and consider the local stability of the plate when the peg spacing and the maximum thickness ratio of the plate. Finally, taking an actual hybrid structural engineering as an example, the applicability of the above method is discussed and it can be used as reference for design.
