I am designing column splice joint of bearing type according to EN 1993-1-8
There exists net tension in the flange, hence I will have to use preloaded bolts & hence apply slip resistance check.
1) Now when i enable check slip resistance, i dont find any option to enter slip factor for it. Then how does RAM checks the slip resistance of the joint?
2) Even after applying slip resistance, warning appears in the result:
"Bolt slip class does not match slip resistance recommendations."
What is the meaning of this warning, as far as i know only 8.8 & 10.9 grades are allowed to be used for preloaded application.
And i have selected the 8.8 grade bolt, so what is the meaning of this warning?
3) Why web & flange coverplates are checked in separate connections?
4) What is the purpose of providing additional plate from inside of column, as far as i know SCI allows use of cover plate either from inside or outside.
I am using RAM connection integrated with STAAD Pro V8i 20.07.11.90
Please give reply as early as possible.
