Noted, however If we design anchor bolt as per ACI 318 appendix-D, the size of the pedestal/column is coming very huge, because of low concrete breakout strength and large edge distance and anchor to anchor distance requirements. As the Appendix-D procedure does not consider the effect of...
Sirs
Can anybody suggest any reference for bond stress as per ACI-318..
i want to calculate the bond strength of anchors is tension. Since I don't have any America code reference, I am using BS8110-1 Clause 3.12.8.4.
ultimate Bond stress, Fbu = β Sqrt(Fcu).
We are using 4000psi Concrete...
Actually we don't have a local supplier for bend angles, procuring material from foreign countries will cost more as well as the delivery time will be more. Because of that we used this approach. We also see no problem with this splicing. My only worry is at the connection point if we provide a...

We are designing a self supporting lattice triangular tower made up of 60 degree angles to support tale-communication antennas. However the 60 degree angle we are using is not hot rolled sections, But we are making 60 degree angle by bending the 90 degree angles to 60 degrees...
Sir
I have designed a tower with ASTM 572 Gr 50 Material with ASCE-10-97 (AMERICAN) Code. But now I don't have ASTM 572 Gr 50 material and I need the structures urgently.
Therefore I am proposing to use JIS SS540 material, as the mechanical properties used in design of the proposed material is...
Sirs
As in my earlier Quarry i requested you to advice regarding the unequal stress distribution because of one continues and one discontinues anlage in the same pair of double angles in a cross bracing.
I tried to find out the difference in stress considering the simple theory of equilibrium...
Dear Sir
I have attached the calculation now, kindly look in to it and let me know if itseems ok or advice accordingly.
Thanks & Regards

Dear Mr. Peddington/Mr. GJC
Sir, your reply was very helpful, However i just want to make a few point's as follows:-
1) Since in the transmission tower most of the crossing diagonals/lattices are compression/tension type and are critical predominantly in compression. Therefore to get...
Dear Sirs.
We have arrage is that way to get some support at the crossing point.If we provide two long angles contineus and other to discontineus ,it means the short angles are supported to the longer angles, in this case the long angles should be designed in compressing (L/R) for full...
Sir
I have used a double angle back to back cross bracing connection in a transmission tower. In the structural detailing we make two members
(one for each group) continues and other one discontinues.
Now my consultant say "if you provide one continues and one discontinues in same compound...
