SDPWS 2015 4.4.1.2.a Use minimum 0.229"x3"x3" plate washers at all anchorage points connected to bottom plates or sill plates to the foundation.
   
    Anchor spacing is based on bolt-to-wood calculations, not bolt-to-concrete. For bolt-to-concrete calculations, please contact Engineering Express.      
    Sill anchor spacing is based on SDPWS 2015 Table 4.4.1.6, Maximum Anchor Bolt Spacing for Combined Shear and Wind Uplift. Engineer of Record to check for out-of-plane loads.
