If u see the diagram there are two flanges and one web so total 6 points I.e four corners of flanges and two corners of web total 6. But We are seeing only one side so, next side another 6 points are there total 12 end returns
After calculating the Required area of the base plate I got 111111 mm-Square. So I provided 360x310 area I.e 111660 mm-square which is nearer to required area so that’s why I choose 360x310 plate. In civil engineering all design aspects will starts from assumptions only. Think practical all the best.
By the area we have a formula to calculate the length and breadth of the plate i'e A=(D+2a)x(bf+2a) 111111.11=(300+2a)x(250+2a) Calculate that above eqn We got a= 29.63 i took 30 mm Then L=(D+2a),B=(bf+2a) L= (300+2x30)=360 B=(250+2x30)=310
It's useful my sem exams
Good explanation sir tq so much sir
You’re welcome
hello bro, what if the ISHB dimensions is not given? how to derive from axial load SBC of concrete ?
If not given simply assume any ISHB section by referring steel tables book or IS 800:2007 code
Thankyou soo much sir. It will help to my sem exams. 💞
It’s my pleasure. All the very best
@@civilworld Sir. Can I get the video on Design of slab base ( column base subjected to moment) problem !
Thanks brother💕
My pleasure brother. Thank you so much.
How to provide bolted connection
As per code bearing strength of concrete = 0.6 fck (IS 800:2007) PAGE 46 CLAUSE 7.4.1
Yes you can take it as per code
That is the maximum value but to design it optimum we take 0.45 fck and it is also wtiteen on in general clause 7.4.1 read it
@@amitabhmajumdarju sure thank you
What is the purpose of @577N/m
Unit weight of the ISHB 300
Brother can u tell me how can u take the number of end returns
If u see the diagram there are two flanges and one web so total 6 points I.e four corners of flanges and two corners of web total 6. But We are seeing only one side so, next side another 6 points are there total 12 end returns
On which page is the formula of Ts written?
Page no 47 clause no 7.4.3.1
Why are you deduct the flange thickness in connection please tell me
Where I deducted the flange thickness? Please specific
@@civilworld total length of the weld
I deducted web thickness 7.6 because to know the total length of the weld and both sides web portion included into the flanges. That’s y I deducted
After deducting that web and flange thickness only we will get the total length of the weld
Because we providing welding for flange and web portion only not for whole plate that’s y I deducted
Just give me proper is code page no for the welding part only
Hi Rahul, please be specific with your doubt.
Explain clearly
Let me know where you stucked? Please refer code book parallel while watching the video

Can u tell me how u provided 360x310

By the area we have a formula to calculate the length and breadth of the plate i'e A=(D+2a)x(bf+2a)
111111.11=(300+2a)x(250+2a)
Calculate that above eqn
We got a= 29.63 i took 30 mm
Then L=(D+2a),B=(bf+2a)
L= (300+2x30)=360
B=(250+2x30)=310
