Is anyone familiar of a mobile app that can do operations with common engineering units?
For example doing something like this would be great:
sqrt(5 W/5 Ohms) = 1.58 A

I have cantilever beam to column moment connection. The column is square HSS, the beam is MC. The channel is welded to the side face of the column by two longitudional welds at the edges of the web. I was wondering how to check if shear lag would be a concern for this connection, since the ends...
Is there a guide to minimum embedment depth for anchors? I have 1" anchors that are only used to resist shear with no tension (equipment support on slide plates). What should I use for embedment depth?
I am unfamiliar with the use of international steel grades. For example can we a European steel grade in the states or does it have to comply to American steel grades?
If I have a footing with top and bottom reinforcement, does the 0.002Ag minimum ratio apply to both top and bottom independently, or is it combined? In other words, which is correct:
0.002Ag < As + A's
OR
0.002Ag < As and 0.002Ag < A's
Hello all,
I have a question concerning foundation design for SCBF systems as per AISC 341. I understand that the whole design philosophy behind SCBF is that all members should remain elastic while your braces undergoe yielding and buckling. Therefore we design our connections for the tensile...
Hi,
We are conducting a preliminary study on a site. I am trying to ballpark our design seismic acceleration but I'm having trouble finding any data as it is in South America. The preliminary geotech report gave us 0.3g PGA with 50% exceedence in 50 years. Is there a way to estimate the PGA for...
From reading the AISC 341 it seems to me that an OCBF would almost always be more economicaly feasible versus a SCBF to design due to SCBF capacity design requirements for beams, connections, and columns, as well as compactness restriction for braces. I understand the ductility advanatages of...
Hi,
I know AISC 341 defines width-to-thickness limits for compression members, but I was wondering if these apply to tension-only braces? Although you design these members as tension-only, compression and buckling will occur in these members upon load reversal, and it might be a good idea to...
I am adding a new platform to an existing steel structure. The IBC specifies a 5% and a 10% allowable increase in load/capacity ratio for gravity and lateral loads, respectively. Does this mean that I can add 5% or 10% to the capacity under new loading conditions, or a proportion of 5% or 10% of...
In the AISC 341 provisions for OCBF bracing, a slenderness limit of 4sqrt(E/Fy) is defined for V bracing. When implementing two-story X bracing, are these braces considered as V braces for satisfying this slenderness limit?
