    Need a rename macro for excel

    Here's my solution using normal functions. No macro required. My approach is to first divide it into bite size pieces, so I deal with each level separately and combine those into the final result. It's easier to debug this way. I have used two columns to find the text for Level1. You can go back...

    welding 304L to 304L with 316L filler metal

    "How can i Ensure that the weld meets the required mechanical strength and ductility criteria" Now that's a different question. The mechanical properties should be on the data sheet for the wire you have in stock. Ooo eee ooo ah ah ting tang walla walla bing bang Ooo eee ooo ah ah ting tang...

    Bolted Cover Plates

    I agree with those who suggest using slip critical bolts throughout. For galvanized steel the coefficient of friction should be taken as 0.175, half that of bare steel 0.35. Ooo eee ooo ah ah ting tang walla walla bing bang Ooo eee ooo ah ah ting tang walla walla bing bang

    PFC steel grade from 1995?

    Even if BHP was producing 300+ at the time you don't know when that particular piece of steel was made, It could have been G250 in stock. Assume it's grade 250 and move on. Ooo eee ooo ah ah ting tang walla walla bing bang Ooo eee ooo ah ah ting tang walla walla bing bang

    IDEA - Knee Connection - Connecting Plate

    Are you using Tekla? Have you tied Tekla User Assistance? Usual practice, supported by long experience, is for the connection to be made in the rafter. As a structural engineer I say the detailing is a disaster. Can you discuss this with an experienced structural engineer? Ooo eee ooo ah ah...

    Brick veneer cracks

    First I'd ask where you are and what type of soil you have? If you are on an expansive soil some cracking would be expected. Next look in AS2870 Table C1, CLASSIFICATION OF DAMAGE WITH REFERENCE TO WALLS Hairline cracks <0.1 mm Negligible Fine cracks that do not need repair <1 mm Very slight...

    Structural steel connection top of column

    Are you in Australia? Wind loads might be significant. You will be designing as monoslope free roof, blocked under. Assuming you have pin based columns then you will need moment connections at the top for stability, hence option 2 is preferred. Keep the columns oriented as you've drawn them...

    AWWA D103 Bolted Tank Lifespan

    Some bolted tanks have an internal liner so sealing of the bolted joints is not an issue. The design life is dependent on environmental conditions; a tank in an arid environment can be expected to last a lot longer than one near the ocean and in the spray zone. Ooo eee ooo ah ah ting tang...

    Tighten bolt beyond yield point - Preload the bolt in the plastic area

    I think this is normal for fully tensioned high strength structural bolts, so there should be information out there. Pretensioned installation involves the inelastic elongation of the portion of the threaded length between the nut and the thread run-out. Specification for Structural Joints Using...

    [NZS1170.2] Deriving wind load on glass barrier on top of wall?

    I suspect your options will not include hiring a wind engineer to give advice. First the good news, I don't think you get Cp,n = 3.0 unless it is a free end. If your barrier makes a 90 deg corner that doesn't apply. Now the bad news. It might act more like a wall on the edge of a cliff. This...

    Setting default layer colours

    When creating a new layer DS gives a list of standard colours; White, Blue, Cyan, Green, Magenta, Red, Yellow. I would like to change some of these; e.g. change Yellow to Orange so that I have custom set of standard colours next time I open draftsight. How can i do this? Ooo eee ooo ah ah ting...
