冷弯不锈钢构件由于其高耐腐蚀性和高阻力重量比而被广泛使用，但其对屈曲的敏感性意味着必须考虑腹板失稳等不稳定现象，其中腹板由于集中的横向力而局部屈曲。另一方面，新兴的铁素体不锈钢具有非常低的镍含量，因此，与铁素体和双相不锈钢相比，它们更便宜且价格相对稳定。他们有前途的未来，旨在开发有效的设计指导，因此，一个新的统一的腹板失稳阻力表达式的基础上，数值模拟和实验结果验证已被提出。
Cold-formed stainless steel members are widely used due to their high corrosion resistance and high resistance-to-weight ratio but their susceptibility to buckle implies that instability phenomena such as web crippling, where the web locally buckles due to concentrated transverse forces, must be considered. On the other hand, the emergent ferritic stainless steel has very low nickel content and therefore, they are cheaper and relatively price stable compared to austenitics and duplex. Their promising future has aimed to develop efficient design guidance and as a result, a new unified web crippling resistance expression based on numerical simulations and thereafter validated with experimental results has been proposed.
