I hope this is the correct forum for this question.
I have a client who is getting some resistance from their local building official regarding the use of Durisol's ICF blocks for a below grade foundation. The primary difference with this system is that their 'blocks' are made from rock wool &...
I am evaluating an existing 3-story hotel for structural modifications. The existing floors consist of a 3.5-4.0" slab on corrugated decking (5/8") supported by what appear to be steels joists. The joists are very similar to metal studs with oval openings in the webs. The profile is a "C"...
This may not be the correct forum but I had to start somewhere.
I have a Heath-Zenith motion sensor fixture M/N SL-5318-BZ-E (purchased in 2012). In addition to the motion sensor it also has a dual-brightness (DB) feature whereby the lights turn on at half-brightness at dusk. Using a 19.5W LED...
I'm at a loss on this and am hoping someone out there might know if the city of Springfield MA had a residential building code in effect in the mid 1920s.
I am evaluating the roof on a single family home that has some issues and I'm curious about any prescriptive code requirements that might...
I have created a number of dynamic "master" blocks inserted into a master layout at various rotations (0, 90, 180).
Each of those "master" blocks consists of other dynamic sub-blocks.
I am trying to extract the X,Y coordinates of the sub-blocks from each of the "master" blocks, one "master"...
Some interesting questions for those who are very familiar with the performance of threaded fasteners:
- Given a 1/2-13 bolt & nut:
How does a coat of bare metal primer affect the nut-to-bolt connection? Good, bad or otherwise?
The threadlocker folks say the paint would adversely affect the...
Every now & then the cursor in AutoCAD 2015 simply disappears. This occurs in pure model space or when in model space through a viewport. The mouse pointer appears wherever it is outside of AutCAD's drawing space or in another application. Entities will highlight if the cursor happens to be...

Typical news person - doesn't know the difference between cinder blocks & CMU or between cement & concrete. I wonder who the "experts" were that CNN talked to.
If we were to actually...
One of my contractor clients has decided to attempt to "slide" a incorrectly located retaining wall to its desired location.
My task is focused more on the mechanics of the "slide" and the steps involved. I have seen this done with pad footings for interior columns but never for a retaining...
Back in the 1960s an engineer in my area (Northeast US) had patented and was promoting a tube slab. It is essentially a one-way joist slab where, instead of using pans, fibreboard tubes were suspended between the top & bottom bars to displace concrete and reduce the dead load. Earlier on in my...
In ACI 318-05 equation 11-5 (11.3.2.1) uses ρw (reinforcement ratio). For typical one-way slabs, shear is highest near the face of the supports. When determining Vc, equation 11-5 can provide a slightly higher value.
My question for the group - Is ρw the ratio of top steel to concrete...
Not having had a wealth of exposure to CMU construction, I'm looking for some insight regarding efficient construction of CMU walls on top of reinforced concrete foundations.
Obviously, proper coordination between the CMU dowels + the CMU core locations + CMU control joint locations + actually...
I just noticed this morning that when I attempt to insert a block using the standard ribbon, i.e. from the Home tab, click on Block, then click on Insert, the drop-down shows the block names, but no thumbnails appear.
I am running 2015 SP2 under Win 7 Pro x64. The only system change I might...
I need the collective wisdom of those who frequent this site regarding the connection between a reinforced CMU shear wall and a cast-in-place reinforced concrete (RC) foundation wall.
With a reinforced CMU shear wall, ACI 530-02 limits the steel stress (grade 60) to 24 ksi.
In trying to...
Just trying to find out if anyone else has had this issue.
Starting from a Layout Tab, I double-click within a Viewport to access Model Space. Then, selecting Isolate Layer(s) from the Ribbon, I select the layers I want to work with and hit <Enter>. All other layers get Frozen. So far, all...
I just switched over (reluctantly) to AutoCAD 2015 after having a hard drive meltdown. Running Win 7 Pro x64.
When I attempted to set a hatch pattern, AutoCAD pops up a window stating: "acad.pat" Can't find file. After clicking OK in that popup, I get another that says No standard patterns...
I have been experiencing the inevitable disappearing cross-hairs when working in 3D model space. It happens with various drawing files, always after working for a while in the model, and always with a Visual Style of Conceptual or Realistic. I've observed no particular trigger that causes this...
I have been asked to serve on a task force to determine the best course of action for my local municipality. This is perhaps more of a legal question than an engineering one, but I'm hopeful that someone has encountered a similar situation.
We have a mill village area that was developed long...
I am temporarily baffled.
AutoCAD 2012 under Windows 7x64.
I have a drawing file with 21 tabs and a total of 90+ Viewports. Anywhere from 1 to a maximum of 8 Viewports per tab.
My understanding is that MAXACTVP applies only to each tab and NOT to the total number of Viewports in the drawing...
I need to call on the collective wisdom of this group regarding a building undergoing renovation.
I have been asked by a contractor to evaluate a partially demolished structure for stability. What is to remain are all of the steel pipe columns, the original roof (essentially flat, 3" thick...
