ABSTRACT:

This paper proposes a new type of concrete-infilled double steel corrugated-plate walls (CDSCWs). The CDSCW consists of two steel corrugated-plates (SCPs) interconnected through bolts, and the spacing between the two SCPs is filled with concrete. Additionally, two vertical boundary elements are assigned at both sides of the CDSCW. This paper mainly investigates the failure mechanism and design formulae of SCPs in CDSCWs under compressions. The unilateral constraint on the SCPs owing to infilled-concrete and the restraining effect on the flexural deformation of the SCPs owing to bolts are considered. Finite element (FE) eigenvalue buckling analyses are carried out to investigate the elastic buckling behavior of SCPs subjected to vertical compressive loads. The formulae for estimating the elastic buckling loads of SCPs and corresponding normalized slenderness ratios λN are obtained. The instability performance of SCPs under compressions is then studied through FE nonlinear analyses, and the stability coefficients φN can be attained. The corresponding φNN curve can therefore be established. The research findings would provide fundamentals for the design method of cross-sectional strength of CDSCWs.
