    Stainless Steel or Aluminum and Fiberglass Connections

    Motorcity, I do need to try and find the values for Fiberglass. This might be a problem, because it's going to be hand layed up fiberglass. The brackets were going to be embedded into the resin of the fiberglass during construction of the panel. If anyone knows where to find such values for...

    Stainless Steel or Aluminum and Fiberglass Connections

    I have some fiberglass panels that need to be attached to an aluminum frame. I was hoping to embed aluminum brackets into the fiberglass and then mechanically fasten the brackets to the aluminum frame. 1) Is there a problem with the expansion ratios of fiberglass and aluminum? 2) If yes...

    Aluminum column base plates

    I'm looking at making a base plate out of aluminum also. Have you found any information on it yet? I'm thinking about designing it in RISA Base, but putting in the Aluminum strengths, i.e. E = 10,100 ksi and Fy = 12*0.8 = 9.6 ksi for 6061-T6 thicker than 1/2" and within 1" of a weld. Does...

    Unblocked Diaphragms

    I have a diaphram that is seperated with 1' gaps, see diagram. I'm trying to decide if this could be considered an unblocked diaphragm. It seems that the shear would have to transfer through the trusses just as it would in an unblocked diaphragm. I know that they require a gap in unblocked...

    High Strength Wood Diaphrams

    I'm looking at an existing building with heavy brick walls and a wood diaphragm. They want to do a seismic upgrade to the building. I'm having a hard time finding shear values that would be high enough to take the load. There is a possibility of the 3x framing members with (2) rows of...

    Fault Maps

    Thanks for your quick response. This PDF shows that you can order these CDs with the fault zones on them. Does it tell you what type of fault it is. I'm trying to find out fault information to use with the 2001 CBC. Is there any free maps that list this kind of information, and if not do...

    Fault Maps

    I’m trying to find information on fault locations in California. I was wondering if anyone knows where to download such maps. I could use some GIS maps or other maps such as just picture maps. One of my co-workers had a book of such maps at her last job down in California, but when she tried...

    Aluminum to Steel Connection

    Thanks, Is it also true that if the steel studs are hot-dip galvanized that you don't need to separate the two materials with the neoprene or rubber gaskets?

    Aluminum to Steel Connection

    I was wondering if anyone knows about connecting steel and aluminum. I want to rivet an aluminum shell to some steel studs. According to this post http://revobiz.dyndns.org/group/seaint/2001a/msg01557.html connecting aluminum and steel is a big No No. I'm thinking that it would be possible to...
