摘要
板件受压性能是构件力学性能研究的基础,不锈钢板件的受力性能与普通碳素钢存在较大不同。论文对不锈钢薄板纵向受压性能进行研究。根据既有试验结果建立不锈钢薄板纵向受压的有限元分析模型,通过数值分析得到其稳定曲线,提出不锈钢薄板受压极限承载力和箱型截面构件局部屈曲承载力的建议计算公式。研究表明,材料本构采用Quach方程所得数值模拟结果具有较高精度。
The behavior of plate in compression plays a basic role in relevant research. There are significant differences between stainless steel and carbon steel plates in structural behavior. Analysis on the behavior of stainless steel plate in compression was presented. The development of FE models for analyzing stainless steel plates in compression was described based on the results of Rasmussen＇s test. And the strength curve was achieved by such advanced FE models with a high degree of accuracy. The explicit strength equations and design method were proposed for determining the local buckling strength of stainless plate and coldformed rectangular hollow section in compression. It is shown that the numerical simulation results achieved by using Quach model are accurate.
