10. Show Stair upper fir connection detail:Architect added detail. <br /> 11 . Car door wall Aspect ratio h/w: The aspect ratio for blocked shear panels is 3.5:1 <br /> (10'/3.5=2.5' reqd). These walls are dimensioned as 2'4.5" rather than 2.5', however <br /> the inside of the rough opening for the door will allow for another 1 .5"jamb to make <br /> the rough opening fit a 16' door (which adds up to 2.5'). Either way, the inside of the <br /> wall has also called out for shear sheeting OSB on the inside and the outside in order <br /> to further stiffen up the lateral resistance. So thisn affectively becomes a "Portal Frame" <br /> and will sufficiently result in a strong resistive wall. <br /> 12. Shear wall specification:All shear wall nailing is specified within the Shear wall <br /> Schedule attached to the plans. For this plan set, all shear walls are called out "SW6" <br /> 6"/12" edge and field which is standard nailing (uno). The length of all shear walls is <br /> the dimension of the wall on the plans with the SW callout (excluding door and <br /> windows typically). Very seldom do we partially shear sheet a wall line, but if we did it <br /> would be identified. Basically all the exterior walls are always sheeted their entire <br /> length with a 7/16" OSB or CDX 4x8 sheeting. <br /> Hold-downs are specified on the foundation and main floor plans. <br /> 13. Specify Stair details:The standard stair detail on A5.1 will be edited. <br /> 14. Size and spacing anchor bolts: Anchor bolt spacing is called out as Y" bolts at 4' oc <br /> for a two story. When the shear calculations in the report exceed 350p1f (limit in <br /> code), the anchor bolt capacity is to be reduced 50%to determine the spacing. By <br /> assuming they have only 50% of their capacity we can calculate a new proposed <br /> spacing. <br /> A Y2" anchor bolt shear capacity is 1650# not counting an increase for duration loading <br /> or special inspection for up to double the allowable. In my structural report you can <br /> find the anchor bolt or shear value of the wall on the page and the "Shear Results" title <br /> in the Flexible Diaphram design sheet (sht 7). Under the ASD shear force column you <br /> will find a "v" heading...it showing the shear stress of each wall. I reference this to <br /> verify the anchor bolts load. All bolts are indicated as prescriptive in the A5.1 detail <br /> sheet as 48" oc. Occasionally when shear is not fully achieved by the anchor bolts <br /> foundation straps may also be added or anchor bolt spacing changed. <br />
