    Backing Thickness

    AWS D1.1 Section 5.10.3 gives "recommended" minimum nominal thickness of backing bars, provided the backing shall be of sufficient thickness to prevent melt-through. For SMAW, that recommendation is 3/16-inch. If melt-through is prevented, is a thinner backing plate allowed? I see for...

    Prestressed Steel Girders

    Could anyone recommend a good design guide or text related to prestressed steel girders? I have a non-composite rolled steel beam bridge (W33x130) with timber deck that needs to be strengthened. Options I've looked at include cover plates and cover plate with composite concrete deck. One...

    UT inspection - "Leg" definition

    I'm not that familiar with UT testing to D1.1 and am trying to educate myself on it. What does "leg" mean? Reference specification for a project says "testing in leg 4 will not be accepted" My thought is that it has to do with the reflection of the wave and the testing of welds where you...

    Crane rail and concrete deck repair

    I have an existing crane rail on timber ties supported by a timber substructure. The concrete deck around the rail has deteriorated and is being replaced. I am planning on forming the concrete to about 2" away from the rail to avoid any flexing of the rail cracking the new deck. This...

    Displacement in local coordinates

    I have a curved bridge in plan (X-Z plane, Y is vertical)with intermediate piers perpendicular to the curve. BETA angles are used to correctly rotate the columns into proper local coordinate system (local Z is perpendicular to curve). I need to get top of column displacement along the pier (in...

    Bolt Descriptions

    Sorry if this is a basic question for most of you, but I am confused by some terminology I have come across in some plans. "Economy Bolts" are called out for a connection. What is the definition of "economy bolt"? Does it conform to ASTM A 307 or some other specification...

    Shear Capacity

    I was wondering if someone out there could provide some insight into the shear capacity equations for steel plate girders in the "Strength Design" section of AASHTO (16th ed). This is in Section 10.48.8. I am trying to determine the shear capacity of an existing plate girder with...
