My company was called in to look at rehab and renovation on a jail built in 1901. From a historic sign, I know the builder for the jail was the Pauly Jail Building Company. For a large chunk of the building, it is what you would expect from a turn of the 20th century building URM with wood joist...
Does anyone have any resources on wall and roof assemblies that have passed the ICC-500 missile test?
I have tried to scour the internet. There is some information about CMU wall sections from NCMA. There is a little bit of information in FEMA P-361. Finally, there is some information in the...
My firm was acquired by a larger firm in the past year, and we are now undertaking the task of unifying the way we do business. One of those items that have come up is our role in defining special inspection requirements and the required code documents. My old firm had a fairly robust set of...
I have been working on a structure loading software for the last 12 or 13 years. I say software but I hesitate to call it a software because it is really a set of interconnected excel sheets. It started off with just a quicker way to calculate the components and cladding loads, and it has...
I am curious about the colors everyone uses when marking up submittals (shop drawings, calcs, product data, etc.)
When I first started working professionally, I was told that red was for engineers, blue for architects, and green for contractors. No one ever told me what this "edict" was based...
I am trying to figure out what the ASCE 7-16 code intends for MRSA drift calculations.
Looking at section 12.9.1.4.2 of the code you have the following:
Furthermore, Looking at Equation 12.8-6, you have:
Based on those two provisions, is the intention NOT to scale the base shear for drift...
We are having an internal company discussion concerning the appropriate application of ACI 318-14 and the design of Sway columns. We are using RAM SS to design the columns, and as a matter, of course, we are conducting a partial second-order analysis. We understand that Bentley's process does...
I have received the submittal for the tower cranes of a 22 story flat-slab building. As expected, the manufacturer has identified a couple of locations where the crane will need to be tied to the building for lateral support. In addition to placing the lateral forces in my slab, the...
We are having a discussion in our office about checking allowable wind drifts. Based on a paper by Griffis, we had settled for a time on checking drifts of a first order analysis with 10 year MRI wind against a limit of H/400. We also had some discussion about appropriately accounting for...
I am working on a moderately tall building with 6 levels of parking that are more or less 3x the size of the typical 12 stories of tower plate. I thought it would be a good idea to run a modal analysis in order to get a better vertical distribution of force. Everything with the strength...
First a little background on how I have been addressing the requirements of Chapter 17. I do not know if this is the case in other areas of the US, but here in the southeast US (Georgia specifically), we as structural engineers are typically responsible for producing the documents required by...
I am about to transition to a new computer and I do not want to lose my CUI settings (to include customizations made to tabs and panels on the ribbon). About 6 months ago when I changed jobs I saved a new .cuix file and though it would be simple to just load it up and be back up in no time. It...
The Back-story
I am a structural working in Georgia. Up to now I have done jobs mainly in the southeast and using "Steel Systems not Specifically Detailed for Seismic Resistance" has served in all cases. The only experience I have with 341 was a result of studying for my licensing exam. Now...
