I need the 1998 version of the code.

Does anyone have a copy of "1998 Minnesota State Building Code". If so, what's the snow load for Redwood County and is that ground snow or roof snow?

in cases w/o downcomers, what is there a practical upper limit to the distance between drums. What are the criteria for determining that?

I don't have a specific design in mind, but I believe you are thinking of a top supported design. Right now I'm interested in bottom supported design. Isn't that where all pressure parts are supported off the lower drum which in turn is supported by a base, saddles or other mechanism? In the...

I was studying the B&W book and I wonder, how does one justify a "bottom supported" design and allow increasingly larger and larger slenderness ratios in the tubes supporting the steam drum. I realize this is a pretty general question, but I'm looking for some basic info here. Mind you, I have...

CSEllc Refer to my original post. "The existing roof construction is bar joists @ 4'-0" o.c. +/-, bulb-tee purlins @ 32 5/8" o.c., 1/2" gypsum board, 2" poured gypsum, 2" insulation & BUR." I would assume the 2" of poured gypsum is reinforced, but there...

I have check the joists and the moments, shears, and end reactions are well within the published allowables for joists of the size and designation. My concern is with the gypsum deck right now.

It's not my choice to use this material, but it is part of the existing building that would get additional load due to snow drift due to a proposed addition. Now if i understand you correctly, at best I could get 22.7 kgf/cm2 tensile strength which equals 323 psi approximately. With a factor of...

I've considered that and will check the joists as well. I just want to have all bases covered before I make a recommendation.

Thank you everyone for responding, but the info doesn't really address my question. I need some resource for determining the capacity of this roof system for additional snow loading due to drift. I'm aware of what can happen if water gets into the system & that is another concern. I'm not...

I am a structural engineer in the mid-west and have a project that would put snow drift load on an existing structure. The existing roof construction is bar joists @ 4'-0" o.c. +/-, bulb-tee purlins @ 32 5/8" o.c., 1/2" gypsum board, 2" poured gypsum, 2" insulation &...

I have a question regarding the load path from a near horizontal diaphrgam (slpoed roof) to an exterior shear wall, as in an eave condition. If the load is low enough, I specify and unblocked diaphragm and call out a Simpson connector to transfer the load from the trusses to the top plate. If...
