wannabeSE, I thought about the RO issue too but the 4'5" was the pier between the openings.

Thanks guys/gals. I was just hoping someone had done this and had an easy solution. Narrow rib deck makes nesting anything into the deck difficult. The architect did not like my idea of core drilling holes down through the deck but I still think a series of stub columns hitting the panel...

Thanks jimstructures. I will check their website first and if I don't see anything, I will call.

jayrod12, Neglecting the temporary waterproofing issue of a slot cut through the roof every 4', I still have structural issues with the bearing wall. A strip of deck 6" or 1'-0" wide will not support 4' of trib roof therefore I would still need something to span between joists, a deep leg track...

CANPRO, I can check but new slope should be about 1:12. For 45' span, mono pitch, 45" of slope. Slope will be parallel to the existing joists for the main part of the roof. Ends will have a hip but whatever solution we use for the main part can be adapted for the ends.

Sorry I forgot to mention that the existing roof is flat / nearly flat. New standing seam roof requires a slope.

All, The owner and architect want to place a standing seam metal roof over an existing conventional bar joist and metal deck roof system. The slope of new roof would be parallel to the joists. Joists span 45', are spaced 4' oc and have panel points about 4' oc. Narrow rib metal deck with 5"...

Thanks Mike. I tend to agree but am concerned that without some pre-loading there will be additional deflection as the WT's take load. They are relatively flexible but unfortunately there is nothing handy to run a perpendicular brace to. Ken

We are rehabbing a 130 year old courthouse. The roof framing clear spans about 50 feet over a central core using 7' to 9' deep girders built up of 1x12's. The webs are two layers of 1x's (flat) diagonally opposed to each other. The chords are then nail laminated to them and consist of 6 or 8...

My old steel beams book shows Bethlem using the BL for light beams as late as 1948 and the book only goes to 1952. Hope this helps.

Thanks Marquis. SomptingGuy, I think that is what they call files that are with the program to get you started. Sample files might be a better name for them. My understanding is that the program will come with some small block Ford files.

Marquis, Whew! The programs seed files are sounding better all the time. I have limited dyno output that may help. I can measure some items. The intake seems fairly uniform in cross section and length but the head ports are obviouusly a different story. I assumed I would have to measure the...

The NAAMM Metal Stairs Manual is a good source of info on floor plate. 1/4" will span about 4' with your load but the deflection will be over an inch. Since deflection governs, what is your criteria?

Applications: One 383 and one 350. Both personal vehicles. The 383 has casit iron heads, dual plane intake and carby. The 350 has AL heads, and TPI. I was hoping to model to match the dyno results and then predict the results of diferent upgrades.
