| 摘 要： | 针对大开孔的补强计算方法——压力面积法、ASME压力面积应力法、俄罗斯ГОСТР52857.3-2007中的极限载荷法以及GB150-2011中的分析法,分别介绍了几种方法的适用情况。通过对大开孔结构的补强计算比较,显示出几种方法的异同之处。提出当开孔率ρ>0.9时,可借鉴极限载荷法进行补强计算。

| Abstract: | Several applications for the calculation methods of large openings reinforcement had been instructed in this article. The calculation methods include pressure-area method, ASME pressure-area-stress method, extreme load method in Russia F O C T P 52857.3-2007 and analysis method according to GB 150-2011. We can get the difference and same points of several methods through comparing to the reinforcement calculation for large openings. When the opening area rate greater than 0.9, extreme load method can be used for reference. |
