On-Site Risks During the Basic Test | Preliminary Verification
Hello, everyone. This is Enta. I conducted a basic test the other day, and the specimen pulled out at around 100 kN. Well, since that test was strictly for determining τ (circumferential friction resistance), that’s fine, but when it pulls out earlier than expected, various problems start to arise…
