I'm designing a simple shoring system, and using PERI MULTIPROP adjustable post shores.
The posts are adjustable with an inner and outer tube assembly that can be locked together.
The technical data from the manufacturer provides a load bearing capacity, but differentiates between whether the...
In my experience (Canada), structural consulting is a hypercompetitive and cutthroat market.
To survive I am faced with the choice 1.) work long thankless hours to produce minimum quality, 2.) put your stamp on something that makes you uncomfortable, or 3.) burnout by the expectations of...
I always try to use latest editions and show the latest (CSA S6-19) on my specifications.
It's a good indicator when a junior engineer copies and pastes outdated specs when they use outdated references. When I see CSA S6-06, I wonder what sort of details were not incorporated.
Also, how are you...
Also,
Clause 4.1 "Materials conforming to ASTM A 992/A 992M conform also to this standard.
But continues to note that ASTM includes additional requirements not addressed by CSA G40.21 (max. yield, max. yield/tensile strength ratio, max. carbon equivalent and max. nitrogen)
So all ASTM steel is...
CSA G40.21 provides "Table 7: Mechanical properties of rolled shapes and sheet piling"
Table 7(a) is Metric and lists Tensile Strengths of Grade 300W ranging between 450 MPa and 620 MPa. (300 MPa yield)
Table 7(b) is Imperial and lists Tensile Stengths of Grade 44W ranging between 65 ksi [448...
Another consideration: Technical calculations are a specialized tool of the trade. Things that we assume are clear are easily misinterpreted by even skillful contractors.
I would try to avoid this conversation:
Contractor: "You have a 100 psf load permitted for this 200 sqft slab. Therefore, I...
Another consideration; Heat. I don't know whether there is zero chance of fire near your tank, but I wouldn't want all your brackets to fail as soon as the temperature rises.
This is an excellent resource. I'm slowly adding to my library and my copy of Blodgett is already in the mail.
I also like Braja M. Das for Retaining Walls/Soils.
Does anyone have suggestions for metal stud framing? It seems we're doing more and more work with that and I'd love some suggestions.
Call you local inspection agency. Often they have deflection and levelness criteria not specified by the code.
For Ontario, Tarion sets the gov't standards for final inspections and they have rise over run limits for walls, foundations, floors etc. (I can't remember them off the top of my...
I'm curious to know if the failures where design problems or construction problems. I've seen enough "interesting" problem solving by the truss installation crews to marvel at the fact more roofs haven't collapsed simply due to poor construction and sloppy inspection.
It's easy to raise the...
Hello everyone,
I am designing an interesting structure, and I was wondering if you people had any experience with anything similar.
I have a heritage masonry facade (3 stories, all-around), with an interior which will be gutted and reconstructed (35m x 16m). The owner is re-building a 3 story...
