SW opening reinforcement calculation
Thread Content
I have a question: when using SW for hole reinforcement calculations, the equal-area reinforcement method fails to meet the requirements (resulting in -2%), while another reinforcement method passes the criteria (+2%). Is this considered a successful calculation?
No problem, as long as any of the calculation methods works. Because any calculation method has a certain degree of conservatism...
Sure. Teacher Qin Shujing from the central station has spoken about this issue. Regardless of the reinforcement method used, as long as it is applicable, it can be counted. However, that 2% margin of yours seems a bit low. It may not meet your company’s technical specifications.
From a design perspective, it’s not feasible because the margin is too small
This probably won’t work; I usually leave a reinforcement margin of around 10% when making holes, as 2% is too small
I think it’s fine; it would be better to increase the thickness a bit more.
