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...
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??
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
