directions. These are commonly located along major axes or centrally within buildings, integrating with vertical circulation elements. Their unique shape enables efficient force transfer and reduces reliance on moment-resisting frames, which helps in achieving open and flexible interior layouts. Their configuration allows them to act as a central spine, providing stiffness and strength in two directions. [1,2]
(SSCPWs) represent a novel class of structural wall systems composed of thin stainless steel face plates interconnected by stainless steel core tubes arranged orthogonally. In this study, a novel bi-directional corrugated SSCPWs is analyzed under axial compression. A parametric investigation is conducted to evaluate the effects of variables such as core tube spacing, tube diameter, and face plate thickness across two distinct wall geometries: L-shaped and T-shaped. Additionally, the study examines how core tube connectors and geometric configurations influence the ultimate load-carrying capacity of the corrugated SSCPWs. Finite Element Analysis (FEA) is carried out using ANSYS Workbench 2024 R2 to simulate the structural behaviour under compressive loads.
1.2 Corrugated Stainless Steel Core Plate Walls The corrugated profile of SSCPWs, especially when using trapezoidal patterns, contributes significantly to improved mechanical performance. Compared to flat plate systems of equivalent thickness, corrugated designs offer superior ductility, energy dissipation, and load-bearing capacity. These characteristics make them highly suitable for use in earthquake-prone zones, where absorption and dissipation of seismic energy are critical. Moreover, the corrugations enhance impact resistance by absorbing local stresses through deformation, effectively limiting damage. This increased stiffness also allows for thinner panels to be used without compromising strength, reducing the overall weight of the structure and potentially lowering foundation demands and installation time.

1.INTRODUCTION The bi-directional stainless steel core plate wall (SSCPW) is intended to offer superior performance in both seismic and non-seismic applications by enhancing lateral force resistance in two orthogonal directions. This multidirectional stability enables the system to efficiently distribute loads under varying conditions. Typically, an SSCPW consists of dual stainless steel plates connected by orthogonally placed core tubes, with copper brazing used to weld the components. These walls can be manufactured in various configurations, including T-shaped, L-shaped, or cross-shaped layouts, depending on architectural and structural needs. By modifying the arrangement, SSCPWs can serve multiple structural purposes such as beams, columns, floors, or wall components. [1,2]
2. OBJECTIVES The main objective of this research is to conduct a comprehensive comparative study on the axial load-carrying capacities of T-shaped and L-shaped corrugated stainless steel core plate walls, focusing on their structural behavior, load distribution mechanisms, and overall performance under axial loading conditions, in order to identify the most efficient configuration for structural applications.

1.1 Bi-directional (L And T-shaped) Stainless Steel Core Plate Walls
3.1 General
L-shaped core walls are particularly suited for buildings with irregular or asymmetric floor plans. They are often placed at corners, where enhanced torsional rigidity is required, or used to enclose service cores like stairwells or elevator shafts. T-shaped core walls, on the other hand, are deployed where structural resistance is needed in two perpendicular
To evaluate the axial compressive performance of the novel bi-directional corrugated SSCPWs, advanced finite element simulations were conducted using ANSYS Workbench 2024 R2. Non-linear analysis is employed to investigate the plastic behaviour of bi-directional corrugated stainless steel core plate walls, specifically in T-shaped and L-shaped
