Sir in this problem for calculating'bs' value we take' wi' value is 50 that is connected distance but in double angle section for calculating 'bs'value we take 'wi'as edge distance y sir can u clear my doubt
Dear Sir For the second question i.e 60 mm leg. We have got an ans of Tdn - 156 KN Tdb - 111 KN And the final ans is 111 KN Can you please confirm whether the same is correct or not. And if its wrong, please share the correct ans.
Hi, Don’t worry about the answers. Because this is practical subject, just follow the procedure. In exams they follow the procedure only. Follow my procedure and do as per your values. Nothing to worry. All the best
It is not about advanced design. We use bita in Tdn when calculating angle section,Page no:33 clause no:6.3.3 in IS 800:2007 When we are calculating plates there is no bita for Tdn formula which is specified in page no 32 IS 800:2007

Minimum pitch distance is 50mm pitch distance means bolt centre to centre distance. total there are 5 bolts so, 4 bolt to bolt spans are there so 4x50. So Lc=200mm. Please refer the diagram. And in IS 800:2007 code minimum spacing for bolt to bolt is not less than 2.5 times the diameter of the bolt. So our diameter of the bolt is 20mm so 2.5x20 is 50mm that’s I took bolt to bolt distance is 50mm. Please refer page no 73 and clause number 10.2.2 for minimum spacing.

@@civilworld thank you
When 90mm leg is connected to gusset, the strength of the plate is 196.364 kN
Pitch distance is 50 so there 4 pitch distances are there that is bolt to bolt distance so 4x50 is the Lc value.
thank u so much sir
You’re welcome
Aap jo rakhe hai o book hai ya steel table book
Yes
How do you get the value of Le
Distance from bolt to bolt is 50mm that is pitch distance code specified total 4 spans are there so 4x50
Sir Anc me se bolt ka diameter bhi to minus hoga

Anc Mai Dia of bold is reduced check
What is the full form of ISA
Indian standard Angle section
Thank you so much 😊😊😊😊
All the best 👍👍👍
What is the value of Lc?
Total 5 bolts are there, so centre to centre bolt distance which is called as pitch distance is 50 mm. In 5 bolts 4 spans are there. So Lc value 4x50
Sir will u please explain the same problem connected by fillet weld...... instead of bolts.....
There is tiny difference in connections only. everything remains same.
Sir Lc value?
Bolt centre to centre 4x50=200 number of spans is 4 each span distance is 50

why you havent subtract the bolt hole diameter in Anc
It’s connected leg
I was going to comment that..I just saw the same problem in ither channels n they subtracted the bolt hole
Exactly here he did it wrong. The bolt dia should also have been deducted since it is the net area
