On page 4-21 of the Seismic Design Manual, there is a calc for the variable Dmin. The book reads as follows: "The minimum required single-sided fillet weld size is,
Dmin=Ru/1.392kips/in(lw)=.784
Could someone tell me what this unitless value represents.
Thanks in advance
I know with masonry shear walls you take the height divided by the depth plug the answer into a chart and get the R value. I also know that rigidity is the reciprocal of deflection. Is the rigidity of a wooden shearwall the reciprocal of the deflection? When designing wooden shear walls, how...
When a shear wall is perpendicular to truss spans, shear blocks are specified over the shear wall. Sometimes I will see on the plans, this line of shear blocking continue pass the point of where the shear wall ends. My question is:
(1) Why is this done?
(2) Why is flat 2x blocking sometimes...
THE 2005 NDS SECTION 3.4-7 SUBSECTION (C)(PAGE 17) STATES: "WHEN CONCEALED HANGERS ARE USED, THE ADJUSTED DESIGN SHEAR, Vr', SHALL BE CALCULATED BASED ON THE PROVISIONS IN 3.4.3.2 FOR NOTCHED BENDING MEMBERS. MY QUESTION IS, WHAT DO THEY MEAN BY CONCEALED HANGERS? THEY ARE NOT REFERRING TO...
