irregular home plan geometry
irregular home plan geometry
(OP)
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 you break the house up into individual rectangles. Or??

start at point a(0,0) and draw a line due north 45', this is point b. from here go 25' due east, point c. move 6' due north, point d, now 16' east, point e, from here continue north 46', point f, from here 24'west, point g, now 5' south to point h, and close by goinging 17' west - should end up where you started (0,0).
anyway, you'll notice that the strut from shearline c-d does not line-up with the wall line g-h. there is an 8' discontinunity in the chord at g-h and c-

If you prefer you can always design cd and gh as shear walls, but to guard against what I said above, I will design ab and ef for full load.

I think the typical residential analysis considers plywood diaphrams flexible and tributary area loads the shearwalls.
