Stainless steel core plate wall (SSCPW), as an innovative type of wall, consists of stainless steel plates that are connected by orthogonally arranged stainless steel tubes. In this study, the axial load-bearing capacity of the T-shaped SSCPW was investigated experimentally and numerically. The experimental results indicated that local buckling occurred in the stainless steel plates although lateral restraining to them were provided by the stainless steel tubes. Finite element models of T-shaped SSCPW were established and validated by the experimental results. Moreover, the nonlinear finite element analysis was used to analyze the influence of different design parameters of T-shape SSCPW including height-width ratio, stainless steel plate thickness, stainless steel tube diameter, stainless steel tube spacing on the axial load-bearing capacities of T-shaped SSCPW. The empirical formulas for calculating the ultimate bearing capacity of T-shaped SSCPW were proposed. The bearing capacities of T-shaped SSCPW specimens calculated by the formulas are in good agreement with those from experimental results and FE results, verifying the safety and effectiveness of the strength design formula of the T-shaped SSCPW.

不锈钢芯板墙（SSCPW）作为一种创新型墙体，由不锈钢板通过正交排列的不锈钢管连接而成。在这项研究中，通过实验和数值研究了 T 形 SSCPW 的轴向承载能力。实验结果表明，尽管不锈钢管对它们提供了横向约束，但在不锈钢板中发生了局部屈曲。通过实验结果建立并验证了T形SSCPW的有限元模型。通过非线性有限元分析，分析了高宽比、不锈钢板厚度、不锈钢管直径、不锈钢管间距对 T 形 SSCPW 轴向承载能力的影响。提出了计算T形SSCPW极限承载力的经验公式。由公式计算得到的T形SSCPW试件承载力与实验结果和有限元结果吻合较好，验证了T形SSCPW强度设计公式的安全性和有效性。
