The invention relates to a combined
steel plate shear wall, in particular to an I-shaped
steel plate shear wall with built-in round steel reinforcement cages and externally-attached steel plate supports and a manufacturing method. According to the I-shaped
steel plate shear wall, the I-shaped section is applicable to the arrangement mode of a
shear wall body in a building structure, the space between the inner sides of two
steel plates is filled with concrete, buckling deformation of the
steel plates can be effectively restrained, and the buckling strength of the
steel plates is improved; due to the fact that the internal concrete is restrained by the steel plates on the two sides, cavity separating plates and the round steel reinforcement cages in a double mode, the elastic-plastic deformation capacity and ultimate
compressive strength of the concrete are improved; the steel plate supports can fully play a role as
diagonal members, and provide high lateral-resistant rigidity and the high
bearing capacity for a
shear wall body; the
flange portion of the
shear wall body with the I-shaped section has a good restraint effect on a web wall, the
bearing capacity, in the plane, of the combined shear wall and the
bearing capacity, outside the plane, of the combined shear wall are remarkably improved, and thus the combined steel plate shear wall can have the high bearing capacity and the high elastic-plastic deformation capacity.
