Does anyone have a welding procedure for welding AL-6XN to carbon steel?? I have searched our AWS D1.6 for any information and I have also gone to vendors with no luck as of now. I realzize it is not a desirable weld.
I have a client asking to use 1045 steel in place of our specified 4340 steel. We require 320-360 BHN and our client assures us he can achieve 280-320 BHN with 1045. From what I've read, this seems unlikely. What is a good source for this type of materials information? Thanks!

My firm is designing a pipe bridge crossing a railroad and a local road. Will the AASHTO bridge code apply in this situation? I am confident in past projects (mostly in plants) the code was not used. Simply LRFD or ASD. I would feel much more comfortable using the code and feel it is necessary...
Does anyone have a good feel for sheetpiling unit costs? I am estimating for about 200-300 LF. I have H pile cost information but not sheetpiling. Thanks!
I have a question about the slenderness requirement for bending in ANSI NDS 97'... Page 17
My Span is 10 ft. = 120 in. = Lu
Member Subject to Bending = 2x6 = 1.5x5.5
Effective Length for Lu/d > 14.3 is Le= 1.84*Lu = 220.8 in
Slenderness Ratio = Rb = ((Le*d)/(b^2))^(1/2) = 23.23
Rb...
I have a W section which is tying in to a parallel 8" masonry block wall. The wall is existing. I am planning to place Reinforced CMU below the seating of the beam. I would like to have a 4" bearing surface but it's not clear how many blocks I should replace with the CMU to provide a sufficient...
