引言 在起重机金属结构中,广泛采用薄板结构。薄板的局部稳定性问题是设计中必须考虑的一个重要因素。利用加肋来提高薄板稳定性是有效和可行的方法,它对于减轻重量,合理利用材料具有很大的意义。 长期以来各国对于加肋板作了大量的理论
Introduction Thin-plate structures are widely used in crane metal structures. The local stability of the sheet is an important factor that must be considered in the design. The use of ribs to increase the stability of thin plates is an effective and feasible method. It is of great significance for reducing weight and rationally using materials. For a long time, many countries have made a lot of theories about ribbed plates.
