摘要
根据密加筋板结构的特点,基于中间有弹性支座连续压杆的稳定性理论分析方法,推导出单向受压密加筋板结构整体失稳时临界载荷的实用计算公式,并与有限元的数值解进行了比较。结果表明,公式形式简单、运用方便、结果准确、便于在工程中实际应用。
Based on the characteristics of the multi-stiffened plates, the buckling strength theory of continuous eolumn with internal dastic supports under axial ccrapression was used to derive the practical calculation formula for the critical load of wholly buckling. The validity of the formula was analyzed by comparing the theoretical results with numerical ones frown FEM, which showed that the presented formula is simple for practical use with quite good results.
