The search for light weight and efficient structural elements is a
continuing process. Reducing the structural weight and improving the
load carrying capabilities of steel frames will allow designers to add
additional capabilities while reducing cost. Corrugated steel plate shear
walls offer several advantages when used to resist both vertical and
lateral forces in a building. This paper is devoted to the buckling behavior
of steel frames with corrugated steel shear walls. The system consists of
two parts, the first one is the envelope steel frame and the second is the
infill corrugated steel shear wall. The corrugated steel plates are
connected to the surrounding frame beam and columns. The buckling load
factor of this system depends on the interaction of many factors including
the corrugation configuration of steel plate, the angle of corrugation, the
depth of corrugation, the thickness of corrugated plate and the spacing of
the fasteners used to attach the corrugated sheets to the steel frame, in
addition to the restraint conditions and the external load action. Steel
frames with trapezoidal or triangular corrugated steel shear panel were
modeled using the finite element software Cosmos/m 2.8 and a linear
analysis was performed. In the current study, elastic buckling behavior of
steel frames with corrugated shear wall is investigated using finite
element approach. The elastic buckling behavior is expressed as
normalized load factor which is defined as the ratio between the buckling
load of the frame with corrugated plate to the buckling load of the frame
without corrugated plate. Parametric analyses were carried out to
investigate the effect of spacing between fasteners used to attach the
corrugated plate to the envelope frames without or with one, two, and
three stiffeners for frames subject to vertical loads only or vertical loads
with horizontal loads. The results showed that the spacing between
fasteners has significant influence on the elastic buckling behavior of the
steel frames with corrugated shear wall.
