摘要
对内河双壳船达到极限状态时剖面上的应力分布情况进行假设,采用直接法对极限强度计算的公式进行推导,并对一条内河双壳实船在完整和破损状态的结构极限承载力进行计算与比较。结果表明,所假设的应力分布对这一类型船舶的极限强度的计算结果具有较高的精度,可以用来估算此系列船舶在完整和破损状态下的极限强度。
The stress distribution for the inland double-hull ships in the ultimate limit state was assumed to derive the formulas for calculating the ultimate strength of double-hull ships based on direct calculation method. A calculation of the structural ultimate capacity for an actual inland ship was carried out for the intact and damaged conditions. The results were compared with the ones from the progressive collapse method. It showed than the stress distribution assumed in this paper is reasonable, and can be used in practical calculation.
