Lateral behavior of trapezoidally corrugated wall plates in steel plate shear walls, Part 1: Elastic buckling
Abstract This paper deals with the elastic shear buckling behavior of trapezoidally corrugated wall plates in vertically or horizontally Corrugated Steel Plate Shear Walls (CoSPSWs) considering constraints from neighboring subpanels and boundary frame members through eigenvalue buckling analyses and static analyses. Results showed that constraints from boundary frame members along the corrugated edges of wall plates had obvious influences on the shear buckling behavior, while constraints along the straight edges had negligible influence. When the waveform configuration remained the same, the global shear buckling stress of corrugated wall plates increased slightly with the plate thickness, reduced obviously with the straight edge length but barely changed with the corrugated edge length. When the external dimension and thickness remained the same, the global shear buckling stress of corrugated wall plates increased most significantly with the inclined subpanel width, corrugation angle, or corrugation depth. Formulas were proposed for the local shear buckling coefficient, global shear buckling coefficient and interactive shear buckling correlation coefficient of vertically and horizontally corrugated wall plates in CoSPSWs considering constraints from neighboring subpanels and the boundary members. A mode factor was defined to predict the dominant shear buckling mode, and a comprehensive formula was proposed to calculate the shear buckling stress of corrugated wall plates, with good accuracy within the given ranges of geometric parameters from practical engineering.
Highlights Constraints from neighboring subpanels have obvious influence on local shear buckling behavior. Boundary member constraints on corrugated edges have great influence on global shear buckling behavior. Formula of local shear buckling stress of corrugated wall plate is revised and proposed. Formula of global shear buckling stress of corrugated wall plate is revised and proposed. Correlation formula for interactive shear buckling stress of corrugated wall plates is given.
