Thank you for your clarification, that's very helpful.
I have follow-up questions if you don't mind:
1- my understanding is that Clauses 1.4.1 (Load Path Connections), 1.4.2 (Lateral Forces), 1.4.3 (Connection to Supports), and 1.4.4 (Anchorage of Structural Walls) are all general stability...
Clause 1.4.4 of ASCE 7-16 states that "The connections must be capable of resisting a horizontal force at the strength level, perpendicular to the plane of the wall, equal to 0.2 times the weight of the wall tributary to the connection, but not less than 5 psf".
I would appreciate some...
Yes, this is performed when shoring the girders is not feasible in order not to block the traffic under the bridge. The girder is reinforced while a portion of the bridge remains operational.
Please refer to the sketch below on a case where the filler plate with big holes is used. Sometimes, the fillers are used with big holes (assumed as slotted holes) to reinforce existing built-up girders. This is done by adding a filler plate having a thickness exceeding the rivet head thickness...
Hi,
The bolt slip resistance in slip-critical connections is Rn/Ω = [μ Du hf Tb ns /Ω] per Eq. J3-4 of AISC 360-16.
For the splice shown below:
(1) What should I use for (hf)? Is there one filler between the connected parts (hf = 1.0)? Or are there two fillers between the connected parts (hf =...

Thank you; so the occupancy load directly supported on the slab on grade (like people, furniture, non-bearing walls, partitions, fixtures) are not considered as "vertical loads" to be transmitted by the slab. As such, the Code does not apply to the design and construction of such a slab on...
Section 20.2.1.1 of ACI 318-14 states that "Nonprestressed bars and wires shall be deformed, except plain bars or wires are permitted for use in spirals."
However, I saw in many projects that they use welded wire mesh with smooth wires in concrete toppings and composite metal decks. Is the use...
Section 1.4.7 of ACI 318-14 states the following "This Code does not apply to design and construction of slabs-on-ground, unless the slab transmits vertical loads or lateral forces from other portions of the structure to the soil."
Could someone please explain to me what is meant by vertical...
Thank you Just Some Nerd. I found this article which provides two methods for determining and assigning the scale factor. I believe the second method is what you referred to.

I appreciate your quick reply. I tend to share the same interpretation of this AREMA requirement.
I'm curious if there is any documentation in AREMA or other relevant sources that offers a precise definition of the "elements" in a bolted built-up girder. I need to cite this information in the...
In AREMA, there is this requirement about splicing the flange of a flexural member "No two elements in the same flange shall be spliced at the same cross section". So, for a bolted built-up girder whose flange consists of 3 cover plates: my question is what is meant by element? Like are all 3...
