Given: Conventional light weight wood construction with premanufactured trusses, shear walls, and platform framing, non-blocked diapram.
My understanding of the load path to the roof diaphragm (for wind load parallel to ridge) is via the gabled end truss connection top (sloping) chord. On some...
I need to supply calc's for the design of a "rock retaining wall" (+/- 8 foot). I'm familiar with concrete cantilevered ret wall design, but have not designed a "rock ret wall," yet. I'm not finding any design guides (or codes) on the subject. The wall will retain the backyard fill of a...
When designing the stitch nailing for doubled 2x's (where used at abutting shearwall panels), is the design load used to calculated the required stitch nailing simply the shearwall capacity.
Any comments are appreciated...........
What are you folks using for lateral bracing for raised wood decks attatched to the house (via ledger board and joists) on one side, and supported by columns on the opposite side. I suppose I could design a steel column w/ moment connections, but I'm not really seeing that in conventional light...
I am designing some floor joists that will be perpendicular and adjacent to a concrete retaining wall. The joist can be top flange mounted to a sill plate ontop the retaining wall. Question: Is there a code which tells me that I would have to use a ledger board between the joist ends and the...
I have a 2-story house with the top plate height of 20 feet.
The top of the roof ridege is 15 feet above that. So, a total height of 35 feet from the ground. When I select the Ce factor, would you suggest using the total 35 foot height or a mean value. This would make a differece of...
What UBC section should I be looking at for design load connection at the top plate. For instance, I calculated the wind load of 340plf normal to the top chord (top plate). Do I need to provide fasteners between the truss and top plate to transfer this load? Any thought are appreciated.
Stratagies are appreciated.
Plan view with north-up(Y-direction)and east-right(X-direction).
Now, draw a horiz gridline labeled "A." Offset a second line 10' North and call it "B." Offset another line from "B" 30' North and label it "C." And, finally...
1. I have both interior and exterior shear wall lines that are offset, 2', 3', 4', and 5. The IRC/UBC seem to allow "braced wall lines" to be offset 4' and still be considered the same wall line. I believe because I'm "engineering" the walls I should not site the 4' code...
conventional light-weight construction of a wood 2-story house in california. in plan view the house has a stair stepped looking geometry (5 steps), and is about 80' wide and 40' deep, wind controls.
Q: what is a strategy for shear wall, chord force, and drag strut analysis. That is, would...
