TDI Engineer,
What methodology do you use to check seismic soil loads against a wall?
The reason I ask is because I recently had a to perform such an analysis for an existing cantilever retaining wall. I was lucky enough that I could use some very conservative loads and the wall was still...
TDI, what is the basis for "On retaining walls greater than 15' a seismic pressure should also be considered in high seismic zone."
The 15' is new to me. Can you please clarify?
Jae & MS,
When the floor joists are X braced together, this transfers the load to the diaphragm. I believe that the X bracing I am referring to serves the same purpose as the bocking you are referring to. Please correct me/explian if I am missing something.
I personally have never seen the...
If you want these channels to split the loads, you need to "unload" the existing channel before installing the new channel. Otherwise, the load the existing beam is already seeing will always be there and the new beam will only take 1/2 of any load applied after the modification.
I would...
The wall that does not see the bearing load from the floor joists still has a joist setting on it along the entire lenght (sets parallel to the wall). The plywood subfloor is attached to this joist, this acts to resist the load as it is essentially a large diaphram. Additionally, floor joist...
For a single story basement. General assumption is the wall spans vertically with end conditions being pinned at the top and the bottom. One could assume bottom to be fixed, but proper detailing of this connection would need to be done. Depeding on type of construction this may or may not be...
I am looking for continuing education oppertunities to development in the structural seismic/earthquate field. I have done some interent searches and everything thing I see is very high level. I want to dig into details and a good solid understanding. Any suggestion?
Thanks in advance!
I would call both of them up and say. "I am sure if I look hard enough I am sure I can find somewhere that you did not meet project specs... Or can I see your documentation proving that you provided the exact ASTM/ACI spec on XXX (you choose, conc mix, w/c ratio, anchor bolt)." Or ask them if...
Be patient. What you are experiencing is not the exception, but the norm. I have two examples for you.
Myself, I graduated in 2006. 1st year raise = 4.5%, 2nd year raise = 9 % (I was told it was because I did such a great job that year, but later came to find out it was cause they hired...
I am looking for advice on how to approach my supervisor for a raise. Our yearly review is coming up shortly. The company I work for is great and I really like it here, however there are a few things that bother me. For one, when I go in for my review my supervisor has a number set for my raise...
