I am doing Load Factor Rating for Truss Bridge. The section 3.8.2.1 of AASHTO Standard specification defines Live Load Impact as 50/(L+125), where L is the length in feet of the portion of the span that is loaded to produce the maximum stress in the member. For a truss member (compression or...
I am designing building floor beams of a building with 3.5" concrete slab on 1" 22 gauge steel deck. The floor beams are steel beams and spaced at abt. 4'-0" centers. If the top flange is connected to the steel deck with 5/8" puddle weld at abt 7.5" centers, can the beam be design as braced beam...
About the reduction in strength of the member. The angle described above act as a cantilever with load applying at the top. Do I have to consider the reduction in the flexural capacity of the angle itself because it will be welded to the plate at one end? That will change the whole design...
How do you calculate the strength of fillet weld while welding two aluminum members? I need to weld an 4x4x1/2" angle to a rectangular base plate. Both the angle and rectangular base plate are Aluminum alloy 6061-T6 with ASTM Designation B209. I looked on AASHTO LRFD Section for aluminum but it...
I am designing slab overhang for negative moment due to vehicle collision for post and beam railings using LRFD. For the design Case 1, I calculated the moment and thrust on the base of the post using value from LRFD Table A13.2-1, for TL-4 for transverse force. Now the problem is it requires...
Can someone please provide some reference for Boardwalk Design (Timber). I know about NDS code and other codes required but I have never designed any Boardwalk.
