    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    That's probably where I got myself confused when I was building it. Ok, I'm going to post this one more time and hope this is it now. lol. Thank you for actually looking over that because like you're thinking, I'm going to try to build this into a more multiuse thing after I get this first one...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    Ok. Ignoring, my bad nomenclature. Is this one good now? I ended up with partially open for both decks and partially enclosed for the porch. Thank you for helping me understand how this works!!

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    Yeah, def have that mislabeled then. I used Aoi for area of openings for the current surface/ direction being looked at and Agi for the current surface/ direction being looked at. Ahh I follow you on that check 2a. Let me get in there and mess with it a bit more and repost.

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    @DanKile Here is the spreadsheet I made (attached)-- with screenshot below. It is not polished at all. But I'm hoping it will be helpful for discussion if I am doing something wrong. I ended up getting "Partially Open" for every instance. The 2 decks and the original conversation about the...

    TR14 NDS Application Example/ Help Needed ("Effective Length")- Continuous Beam with Inflection Points

    I follow you on the LTB comment. When I took my research on all of this to the end. I ended up following the gist of what you had said from your experience. Essentially with the joist framing into the beam on such short intervals (16" or 12" depending on the situation). And with lateral...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    I I follow you. I may post my spreadsheet here tomorrow where I did all of this. I think my calculations are correct. I just don’t think I understand how to interpret them. The deck I was working on was 14 feet out from the house and 20’ wide (parallel to the house). The right side of the...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    I follow you now I believe. But by this concept. Does the deck also fall under “partially enclosed”. ASCE 7-16. I hope not, the attachment is a structure that I would say is pretty much like my deck situation and they classified it as “partially open”. Also, thank you for being helpful and not...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    Ahh I had no clue. So if 1 direction of the enclosure classification is “true” for partially enclosed- using their provided formulas for classification. The structure becomes partially enclosed? Is this because, it produces the most conservative results using the .55 figure? Or that’s not the...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    I may as well ask this also while we’re on the same subject. What enclosure classification would a ledger attached deck have on the back of a house. I think I chose open with obstructed flow for 7-10- maybe I should’ve chose partially enclosed however. But to me this has a hole in it also, pun...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    Thank you for that guide name. I didn’t even know that existed. I have a spreadsheet that has each cardinal direction in it and it failed the criteria for partially enclosed from every direction but 1 I believe (I don’t have it near me to look at at the moment).—this is only true if I was...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    I follow you on this from a practicality standpoint. When I start applying the formulas, it sees awfully easy to not meet any of the classifications from all directions. Which if I am doing this correctly, automatically kicks you into “partially open”.

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    @Ron247 @Respawn Sorry, yes. Classification for wind. I ended up using 7-16 and choosing “Partially open”. I looked at it from each cardinal direction following asce 7 and I couldn’t get the porch structure to meet any of the other classifications (from every direction at least). It seems...

    Need Help/ Opinion of Classification of Structure (Porch Addition) Based on ASCE 7-10 or ASCE7-16

    Hello, Can you all give me your thoughts on this. I'm struggling to put this one in a classification. I have not used ASCE 7 very much at all. The front opening is 10*10, the side opening is 5*10. Porch is 10*10, Roof line is 10*16 (on the angle). It has a full back wall, full left wall, and...

    TR14 NDS Application Example/ Help Needed ("Effective Length")- Continuous Beam with Inflection Points

    Thank you for your response here BAretired Thank you also for the idea about the pattern/ skip loading. I hadn't really thought about that where I was so focused on understanding this one concept. I will put that in my model so I can see the results. I follow you on the hand methods, I just...

    TR14 NDS Application Example/ Help Needed ("Effective Length")- Continuous Beam with Inflection Points

    Hello, Could someone here help me understand the process of using NDS TR14 and how to apply it to the attached beam. I don't think I understand the process. Do I look at this as 3 separate spans and find the maximum moment inside of each span as well as the quarter moments in each span for use...

    NDS Supplement design values: nominal or actual dimensions?

    They are nominal as you are thinking.

    Deck Pier/ Column Footings (Small Loads)- Confused myself completely (theory/ practical discussion)

    Thank you for your response here. I'm sorry it took me a bit to get back to this thread. Also I understand what you are saying about the small loads and no "structural" requirement for rebar. I think any rebar I provide would be for longevity/ tying the structure together after cracking...

    Structural 3d Modeling- Theory help needed (AWC/ NDS- Deck)

    Yeah, I work on the construction side so there aren't many calculations going on. Out of school, I worked for a place that designed the structure for power plants for 5 years or so. All steel work. (PE in 2010).-- But since 2011, I've been at the DOT. "Fun" is most definitely an overstatement...

    Structural 3d Modeling- Theory help needed (AWC/ NDS- Deck)

    Yeah, I'm not sure where that one comment came from. And I'm using AZEK pvc so it is in the same idea you are speaking from. Thank you for the information on the joist/ beams. For the joist, in my case. It looks like L/480 has been met. For the Beams/ Girders. I have very low displacements...

    Structural 3d Modeling- Theory help needed (AWC/ NDS- Deck)

    I follow you about verifying the model by hand. I can do that. For me, it was more about assumed "theoretical" conditions vs. how the real world actually functions. With no real world experience, I just wanted to make sure I wasn't making an inaccurate assumption about the way a connection etc...
