flat-hat

The effects on buckling stress of the changes of the stiffener rigidity, shape, dimension and location, as well as the required adequate stiffening rigidity of flat-hat stiffened plates are put to analysis in details in the paper.

文中详细分析了帽形肋条的刚度、形状尺寸和位置变化对中间加劲板件屈曲应力的影响，以及帽形中间加劲板件的充分加劲刚度的计算。

A program finite strip analysis model is formed and finite strip computer software is also made in this paper. The buckling behaviors of plates with flat-hat intermediate stiffener are analyzed by employing finite strip method.

论文建立了有限条法分析模型，编制了有限条计算程序，用有限条法分析了帽形中间加劲板件的屈曲和帽形肋条的加劲性能。

On the basis of all these analyze, a reasonable dimension limitation for the flat-hat intermediate stiffener is given, in order to provide reference for designs and the revising of design specification.

在分析基础上，论文给出了中间帽形加劲肋合理尺寸的建议，可供设计和修订设计规范参考。
