I like to get an opinion on shallow foundation on top of hill or adjacent to slope (on high side). This is an addition of three story sunroom to existing house where foundation will be at high side of slope. Per IBC Figure 1808.7.1 if the distance between edge of slope and face of footing is...
I came across a situation where contractor ran out of grout under steel base plate and 1" of portion remained empty without grout under base plate. Does anyone suggest a good retrofit solution?
I am thinking about installing shims and welding together. its about 20" x 20" x 1 1/4" base plate...
Yes. The new 2x6 wall will have sheathing to resist lateral forces(panelized construction)and will be anchored down to footing at basement slab level.
The existing one story masonry wall which was supporting roof will be braced at top with clip angles at top of each studs and it will become...
Well,
I think the way I see is, if additional 2x6 wall can be built inside that goes all the way down to basement footing in that case exterior cmu+brick will become just veneer. it will require flashing at top where second floor starts and 1" gap between existing masonry and new 2x6. So all...
I would like to get some opinions on existing residential single family dwelling unit.
It has 8" CMU walls in basement and embedded 2X joists and 4" CMU + 4" brick above at first floor. Now owner wants to put additional story (second story) on it. In this case what is the best solution?
Also...
I was reading a thread http://www.eng-tips.com/viewthread.cfm?qid=296655 and wanted to get more input on same question.
The metal deck will run perpendicular to the bar joists (in my case). Its wide rib roof metal deck so it has 6" o.c. for ribs that will be in direct contact with framing below...
Thank you IsaacStructural:
I have few reasons for not to put up a ledge angle, of course one as you mentioned is corrosion, second is condition of existing masonry wall and anchoring to existing masonry wall and third the load will get transferred anyway regardless of you support directly on...
Like to discuss an option for an addition/renovation where we are adding a full height brick at existing masonry foundation wall. I am proposing to add an additional course of 6" masonry from footing to little blow grade and have brick rest on this new stem. Of course footing will need to be...
@hokie66:
If there is a flexible diaphragm and if one would use beam column method the remainder of the walls are still going to be braced with floor framing. Isn't it the same scenario as of basement foundation wall running parallel to joists direction where only bracing there is plywood...
Thanks ron, I will red flag and have admin delete the post.
Yes, it is great place to share knowledge. As there are many different ways to approach engineering and this place provides kind of consensus and confidence :)
Just to read different threads gives tons of knowledge more importantly...
Thanks Ron,
Appreciate your input. Yes, I did post it by mistake in the different forum and wanted to delete it but couldn't find anything to remove/delete posted thread.
Can you help me with that too? I am kind of new to posting threads.
Thanks a lot.
I would like to discuss possible options to design basement foundation walls in the middle of basement that is unbraced from top. This situation will arise when there is a open to above space in the basement at corners or in the middle of basement. There will be two approaches I would consider...
I am planning to use bar joists as roof framing members at open structure such as gas station canopy. Will there be any special connection requirements? Is it better to go with just steel beam framing?
Thanks Hokie66 and paddingtongreen.....I thought the same, in reality the pressure distribution will not be the same as uniform but we are applying rectifying force to resist column applying more pressure so before it applies pressure to bottom of footing than limited by tension pile, the pile...
Thanks paddingtongreen, however I do have spring constant but I do want to use soil pressure wouldnt that analogy same as strap beam where you are balancing the moment with another footing and load? In this case we are resisting force couple with tension pile.
I am trying to design a footing that is eccentrically loaded and I am using tension pile to resist uplift. In this case whether to consider soil bearing pressure uniform under footing just like when designing Strap beam?
