A residential contractor is telling me that 3/8" differential for a 32" distance on concrete is an acceptable construction tolerance. Where would he come up with something like that? Can someone point me which standard he could be referring to? He claims his concrete floor can have that much...
I have client describe the following happening at her house:
"I have the most disturbing noises inside the walls, it sounds like things are falling not just settling noises, bought the home 1.5 years ago after 5 months I heard strong noises and some are settling but these noises are out of the...
I recently did an inspection on an 18 ft span beam lintel, most likely made of an LVL beam (Drywall is still in place). The beam is supporting half of a 2nd story, roof and brick. The brick is supported on a steel angle which in turn is bolted to the LVL beam. The beam is currently at a...
What is your opinion on a very long Lu and very tall upper roof, against a very small lower roof and in which the calculated drift width W ends up being a LOT larger than the lower roof width?
Would you then use the drift width W the same as the lower roof itself or would use a truncated snow...
Can someone show me an example of calculation of equivalent fluid pressure when a retaining wall is designed to support the soil + water the full height?
Thanks.
I have to design a concrete pit, with water table at ground level. I am a little confused at what is the actual design pressure I have to use:
Option A: Water pressure 62.4 psf and I ignore the soil weight?
Option B: Water Pressure 62.4 psf + Active effective pressure which I think is (115 pcf...
A client did some "custom" floor trusses with simpson "MP-36" and "MP-24" mending plates. The plates very specifically say that they are NOT to be used for trusses.
I have to verify the trusses. Any one has had any experience in using these plates as truss connectors?
The client did install...
Can someone give some advice on how to figure the maximum height of brick veneer withou providing intermediate lintel support? I am talking about more than 50ft of brick. Should it be supported at intermediate floors? (I am not talking about lateral support)
Does anyone has a reference or know that a brick veneer wall can be used to support an 8ft wide exterior canopy roof? The backing of the brick veneer is 12" CMU. THere is 2" space between them. I would like to anchor angles @ 24" o.c. to support the small roof trusses. Anyone has any...
I am designing a 3 story residential house, with a combination of steel columns, steel beams to support floors, with a combination of wood bearing walls and other wood wall components.
Is there any issues I should be concerned, such as when I will specify 40 ft tall single columns...which will...
Has anyone used Revit Structure modeling/drafting software? Have you used along with Risa3D? How does it compares with CAD Studio from Ram international?
Is it true that a wood header is not allowed to support brick veneer? How would you support a 20 ft opening with 16 ft high of brick? Assuming that the entire building frame structure is made of wood. (Would an LVL qualify?)
I have a concrete retaining wall 14ft tall on which a 30ft tall masonry block is going to be built. Can I have control or expansion joint on the wall or should it be built monolithic the whole length. The wall is 115 ft long.
Other than seismic, what other lateral loads would you consider for a mezzanine? The mezzanine will be used as a gym with stationery bicycles and running pads.
Has anybody had any experience with steel truss girder supporting roof wood trusses? Is a wood nailer possible on the top chord of the girder truss?
Input will be appreciated.
Thanks.
