“…To eliminate the coupling phenomenon between transverse bending and inplane stretching during deformation as well as to avoid additional moment caused by eccentricity, the uniformly distributed load is considered to be applied within the neutral surface. In the case of SP, the relative position of neutral surface from the middle one can be calculated by [7]:…”

“…A series of comprehensive studies on full-life cycle material properties of SC bimetallic steel hitherto have been reported, in which different service conditions including fire [2], post-fire loading [3], marine atmospheric corrosion [4], cyclic loading [5] and impact loading [6] are considered. On the topic of mechanical performance of structural members, limited but increasing attention has been paid to SC bimetallic steel members such as plates [7], columns [8] and connections [9].…”

“…Therefore, a series of basic studies looking into the stability of SC bimetallic steel members, from plates to columns, have been conducted by the authors. Combining theoretical analyses ranging from elastic to inelastic stages [7] as well as experimental investigations of stub and long columns [8], the authors aim at establishing a set of buckling design methods which can provide a solid foundation for the future application of SC bimetallic steel in structures.…”

“…A previous paper presented by the authors [7] addresses the elastic buckling of internal SC bimetallic steel plates in hollow section columns or I-section columns, which can be also refereed to simply supported plates. The nominal elastic buckling stress of such plates is derived using two different theories, i.e., the classical plate theory (CPT) and the first-order shear deformation plate theory (FSDT).…”

The application of stainless-clad (SC) bimetallic steel in various conditions such as offshore and marine environment requires members designed in different cross-sectional shapes, which consist of both internal and outstand elements. To form a comprehensive understanding of buckling behaviour of the SC bimetallic steel members, the behaviour of outstand compression plates needs to be investigated. In this study, the theoretical elastic buckling stress of outstand SC bimetallic steel plates subjected to uniformly distributed uniaxial compression is derived. Considering the position of neutral surface, the energy method and Ritz formulation are used to solve the buckling stress. Adaptation of the first-order shear deformation plate theory (FSDT) is used to modify the solution, which is further compared with finite element analyses. The influence of different parameters such as cladding configuration, clad ratio, elastic modulus ratio, aspect ratio and width-to-thickness ratio on the elastic buckling behaviour of the SC bimetallic plates is analysed. The simplified design formulae and design requirements are summarized to form a comprehensive design method.
