    Identification of Steel "K" Joist

    We have a client who has a supply of several K joist in his fabrication shop and he would like to use them on a new project. Our client does not know what the designation of the joist are. We have been throught the 60 year manual published by SJI without any success as to what size they are...

    NCEES Structural Exam

    Wait until the New Madrid fault slips then you'll all be scrambling to learn seismic design.

    MR connection-cantilever beam to a cantilever column web

    I would recommend horizontal stiffners welded to the inside of the flanges both sides with full pen. welds to the beam flanges. The stiffners are welded to the column with two sided fillet welds. I then weld a vertical shear plate to the column web and bolt it to the beam flange. I have...

    NCEES Structural Exam

    With the advent of the new all-governing intenational code 2000, the following questions have come up:<br> <br> 1. Has anyone heard if California has any intentions of merging their SEOC structural exam with the NCEES national structual exam? <br> 2. Will California ever allow NCEES...

    load capabilities of steel fletch plates

    I think your confused on what a fletch beams traditionally consists of. A fletch beam is compsosed of two wood members sandwiched around vertical steel plates. Through bolts connect the composite members together. They are not typically cover plates as discribed by Imaginner. See...

    CoffeeMug,<br> <br> We have an Engineer in our our office who spent alot of time in North Caolina. He says that on multi-bldg. projects they whould get 40-60% of the original fee after the first one. <br> <br> The problem here is that there are alot of engineers working out of their garage who...

    Stuctural fees vrs. Civil fees.

    Check out the article &quot;Rethinking Bottom Line Issues&quot; by Ronald R. White in the Winter 1999 issue of Structure Magazine. There are some interesting observations about Structural fees and profitability. <br> <br> Now here's a question:<br> In my area of the world, here is something...

    Who checks the z-equation?

    I have heard that the z equation has been totally re-writtenin the new iternational 2000 code. I'll bet it follows ACI to the letter.

    Structural Analysis and Design Software

    To Davida:<br> <br> Check out a company called Keymark. I tested a beta program by Keymark, designing light gage steel trusses in 1994, which probably has improved greatly since than. When wood was getting expensive in the early '90s, we did a lot of light gage steel design for residential...

    Stuctural fees vrs. Civil fees.

    Hey here's a question sure to stir the pot. <br> <br> Why is it that Civil Engineers can demand higher fees for less liability when compared to Structural Engineers? Why can't Structural Engineers charge fees comparable to higher Civil rates?<br> <br> From what I can tell Structural Engineers...

    Drage Forces on Flags

    I haven't seen anything published but I've seen several designs using a 50% flag size with the normal force method. Contact flagpole mnfs. located in the SWEETS catalog for more info.

    Structural Draftsman

    Wow, talk about a can of worms. Thanks for the info....and then some. <br> <br> By the way, state structual plancheck employees in our area are overpaid and take pride in, not only boggin down job progress, but actually stopping it when they can. Not since lawyers, have so many made so much...

    Design of a Tower/Skyscraper

    You might want to investigate the Texas A&M bond fire structural failure. That structure was conceptually similar to a spaghetti structure except built with logs. The intent was to bundle many together in order to increase buckling capacity by increasing KL/r.

    Load Distribution Among Fasteners

    Interesting question. As a structural engineer, we assume the load is always equally distributed. However, it seems to make sense that the end connection could potentially see the most load. <br> <br> I have found no provision in the 1997 UBC to support this and wonder if a cyclical loading...

    Ev factor in seismic design. (1997 UBC)

    Thanks JAE,<br> <br> I hope the 2000 code has more insight into earthquake load E. I have seen engineers place Ev horizontally in combination with Eh and vertically with the DL. Thanks for comments again.<br> <br> The most helpful reference I've found is the PCA publication &quot;Design of...

    Structural Draftsman

    A good structural draftsman in my area with 10-20 years experience can write his own ticket, 45-60 k per year.<br> <br> Quality doesn't come cheap, nor should it!

    Ev factor in seismic design. (1997 UBC)

    Been there, done that. I just wanted to know if anybody had some common sense explinations.

    Structural Draftsman

    Thanks for all the entertainment but can any body help with my initial question? Where do you find trained structural draftsmen whithout stealing them from other firms?<br> <br> By the way, hasanh, if your doing your own drafting, your loosing money.
