slip resistant connection in RAM

What kind of connection specifically did you have in mind? With STAAD.pro SELECTseries 6 we can perform connection design to the Eurocode (EN 1993) and we offer a variety of joints and bolt options, including HSFG bolts if that's all you need.

1) Oh yes i will have tick the check for slip resistance in left column.
Now I want design beam to beam splice joint
In addition to ordinary bearing type joint i will have to add
"check for slip resistance" & HSFG bold grade instead of M16G_8.8 (lets say).
Am i right?
But still i found warning
2) Bolt slip class does not match slip resistance recommendations. Why?
Also for HSFG bolts can have 2 property class 8.8 and 10.9
3) So which property class is used when we select HSFG bolt?
4) Also when i use 4.6 property class for fin plate connection supporting beam web it give warning
Unsuitable bolt grade for recommended detailing.??

With regard to your fourth query SCI Publication P358 recommends on page 109, section 5.3, that 8.8 bolts are to be used. I will look at the requirements for HSFG bolts and get back to you.

Can you please upload your file in order that i can review the issues?
