    User's Guide for the National Building Code of Canada 2020Jus

    Taking a quick read through it, there is a large portion dedicated to seismic commentaries (nearly 50% of the document) which seemed to have the biggest change in the code. They've included some worked examples of calculations as well which is great. Given the overhaul of the seismic sections...

    Tempered window requirement in Canada

    Having trouble getting the attachment to edit into my first post so I'll post it here.https://files.engineering.com/getfile.aspx?folder=3112a983-d206-42fb-a561-02f9406d2594&file=CAN_CGSB-12.20-M89_Structural_Design_of_Glass_for_Buildings_-_Withdrawn.pdf

    Tempered window requirement in Canada

    Take a look at NBCC 2010 3.3.1.19.(6) which states: If you're window is low enough then it sounds like you'd need to design it as a guard, which would have its own requirements, some of which may require it to be laminated, tempered, or wired. I don't have the glass standard that's referenced...

    Ridge Packing

    How about a sloped top-flange hanger from Simpson. Take a look at the figure on the last page of this document.https://files.engineering.com/getfile.aspx?folder=2cc56920-0383-4f82-b5ae-66466b530342&file=C-C-2019-p162-164.pdf

    i get instabilities in my very simple RISA 3D model. Need help. URGENT

    When you run your model and get the instability warning click "Yes" on the popup for "Unstable Model" then look at your joint reactions, wherever the word "Locked" is listed is where you need to modify the connections/supports.

    Repairs for connecting steel beam to floor joists

    The nails driven in on a 45 degree angle are likely installed correctly, see the attached for reference.https://files.engineering.com/getfile.aspx?folder=00bc7635-fd9e-4511-b85d-d3f14393022c&file=C-C-CAN2018-1.pdf

    Filigree

    I believe SSD stands for Surface Saturated Dry, meaning that the substrate would be wetted so the surface is dry but the voids below the surface are saturated. It would be to prevent a weak interfacial zone between the substrate and overlay by preventing the substrate from absorbing mix water.

    Specifications; notes on drawings

    I prefer the first option, but that's only because I think the useful information should lead and the U.N.O. is typical and would apply to most specs.

    Ontario Building Code - when will it be updated to conform to NBC?

    See this thread here for a previous discussion on this topic: Link Edit: Just realized that you participated in that thread as well. I haven't heard of any new updates on code adoption since that discussion.

    ETABS Import DXF File Issue

    Is the DXF file located at the origin in AutoCAD? Or does the insertion point in ETABs match the coordinates in AutoCAD?

    Rubble Stone Veneer Anchorage

    We recently used Link on a project. Reps came out, installed a tie, and performed a load test. I believe the results were quite good. The tie was fastened back to a wood stud wall, there was an insulation layer.

    S-Frame general use questions

    Hey All, I figured I'd throw this question out here, as I've searched the forum and most responses related to S-Frame are quite old. For those of you with experience using S-Frame and the subsequent suite of programs, how do you find them for general building modelling? At our company we use...

    Python application discussion

    Great idea. Thanks for making this thread. Do you have any resources that you'd recommend to start with for someone looking to get into python coding in general for structural? My programming knowledge is pretty limited, just first year computer science in university.

    Volume Effect Factor

    If this is analogous to the KZbg (size factor) from the CSA O86-14 wood code then the notes for L are as follows:

    Truss Reference Material

    You may want to start with the TPIC documents Link. I believe they get into the finer details of joint capacities, as well as modelling methods based on insertion points.

    Rural Bridge Collapse Immediately After Opening

    Link, the article claims that excessive pile settlement caused one of the spans to collapse.

    Embedded Wood Post Detail

    What about using a Simpson Moment Post Base? Link. I've never embedded wood posts for these types of structures, maybe someone else can comment on the performance. I know moisture/rot is a big concern. I typically only embed wood for temporary signs.

    SMath Solver Problem

    After skimming this forum post Link it appears that adding 'ft to the x variable will allow the solve command to run, although I don't believe it will assign units to the "res" variable you've set. I've updated your previously attached file with the change. Not sure if this is the best way to...

    Fasteners through Truss Plates

    What I've heard from truss suppliers is that anything that gets driven in without pre drilling (nails, screws) are likely okay to pass through the plate. If it's bolts or pre drilled holes then I usually seek out their approval. My experience is fairly limited on this though.
