    ASCE 7 Wind Loading of Perforated Surfaces

    Thanks civilperson... it's amazing how much more I can get out of a document if I actually look at all the Tables IN the document. This does the trick. breaks

    ASCE 7 Wind Loading of Perforated Surfaces

    I am currently designing aluminum "fins" (about 12" wide x 4" deep) to hang from an existing 12-story building. They are being added solely as an architectural feature. In an attempt to limit the wind load force, we are exploring using perforated aluminum to fabricate the fins. The perforations...

    Maintenance of Traffic Issue....

    Thanks gbam. I am currently using 1-foot clear which may end up working. All the concrete cutting machines/saws I've seen have a blade on one side which only juts out about 3" from the body. That leaves about 9" buffer. But I will carefully consider increasing the 1-foot dimension based on what...

    Maintenance of Traffic Issue....

    Hey all! I have a question regarding maintenance of traffic and clearance requirements. I have a widening project where we're maintaining traffic adjacent to a work area. The existing full-depth pavement is going to carry 4 lanes next to the work area. The work being done adjacent to the...

    How to Customize toolbars in MicoStation J

    Not sure what the exact problem is, but I create my own toolbars in Workspace->Customize. You're saying you can't create new toolboxes (and get them to save) in this location? I believe my J settings are saved on my computer - because I don't move from computer to computer, I don't know anything...

    Cell Library Disappearing!

    I've been working on a project that has a certain cell library attached to each MS file. For the last year, the line terminator has worked perfectly. Now, in a few files, when I go to terminate a line using the "Place Active Line Terminator", there is no cell recognized. When I go to...

    Column Shear!!

    Yes, shear should be checked in columns. The reason you probably don't hear more about shear in column design is that most columns are primarily there to support a certain axial loading, not shear. Shear loads are normally taken into account for the entire structure or column/beam system. The...

    Highlighting, in color, an area on a Map...

    There's definitely a learning curve! I suggest using a filled shape to "highlight" the region of the map you want (try different colors to see what works best for you). To see the map over the filled shape, you may need to change the order in which the file visually updates. One way...

    load limits of steel I beam

    I agree with Austim. Try using the yellow pages to find a licensed Structural Engineer in your area to provide the required calculations.

    Virginia Standard Lane Width

    The standard travel lane width in Virginia (and most states) is 12 feet.

    Tributary Area

    If the beam you are looking at is continuous, then you need to analyze it as such. You should always strive to be as precise as possible when modeling structural elements. A possible exception to this is when a load case is so minimal that minimal design requirements would control even with a...

    Concrete bearing stress

    Also check out the AISC Steel Manual (9th. Edition), pgs. 2-141 to 2-144 for bearing plate design examples. Not sure if your situation is the same, but there are some basic principles that may help you out... Matt
