Does anyone have any information about strength reduction of Concrete (high strength and normal strength) at extreme temps (270-330 F). I can only find reports in the (527-1112 F)range. Im looking into using a concrete storage tank. However the consultant that I have been using says it can't...
I am reviewing the wind loads used in the design of several buildings at our plant. The wind speed used in the design is 120mph (ASCE-7 02). My question is, this is the 3sec gust, so how can I relate this back to the Saffir-Simpson scale which is based on a 1min average. The NWS says the...
When I started at Schlumberger they sent me a book called "A Primer for oil well drilling" and "Hydrocarbon exploration and production. Both great books for the novice.
I'm looking for some general notes on site perperation for a passive barrier systems (i.e. Concrete blocks). I'm not sure what conditions the field might encounter. Un-level ground, marshy ground, etc.
I'm looking for material properties for both 4140 steel and HY 80. I am highly interested in impact testing and ductility of both materials at low and high temps. Also I'm looking for the normoralizing properties of 4140 and its effects on impact and ductility. If someone has any information...
I'm looking for a material specs book which includes a list of all ASTM metals and their Fy, Fu, etc. Does anyone here have any direction to send me in??
My company works on things like this all the time. We have well over 20 years experince in this area. In short of sounding like a salesperson. The first place I would start is look into SDOF (single degree of freedom) analysis.
All ready tried they only go as far as 56. I've got a guy sending information from CRSI which is suppose to have information on evaluation of reinforcing bars in old reinforced concrete structures.
After futher clarification with the client I believe you are correct in saying that they are looking for information on concrete design standards from the 20's. However in my research of things I can only go as far as the 50's. Any help please??
Does anyone here have a clue to what CIRCA is and were I can find a copy of it. To the best of my knowledge it is a Concrete Code, but no one seems to of heard about it.
Thanks
