<br />1. Loads may not be increased for duration of load.
<br />2. Higher download can be achieved by solidly packing grout in the 1 " standoff area before installation of the post. lowable download shall be
<br />based on either the wood post design or the concrete design calculated per code. Section of Table Used to
<br />3. Concrete shall have a minimum compressive strength of f'c = 2,500 psi. Compare Loading of Columr
<br />4. Tabulated rotational stiffness accounts for the rotation of the base assembly attributable to deflection of the connec r, fastener slip, a .
<br />Designer must account for additional deflection attributable to bending of the post.
<br />5. To obtain LRFD values, multiply ASD seismic load values by 1.4 and wind load values by 1.67 (1.6 for 2012 IBC).
<br />6. In accordance with IBC, Section 1613.1, detached one- and two-family dwellings in Seismic Design Category (SDC) may use "Wind and SDC A&B"
<br />allowable loads.
<br />7. Foundation dimensions are for anchorage only. Foundation design (size and reinforcement) by Designer.
<br />8. Allowable load shall be the lesser of the wood assembly or concrete allowable load. To achieve full wood assembly allo able moment loads,
<br />additional concrete design and reinforcement by Designer is required.
<br />9. For loading simultaneously in more than one direction, the allowable load must be evaluated using the following equation (Design Uplift / Allowable Uplift,
<br />or Design Download / Allowable Download) + (Design Moment / Allowable Moment) + (Design Lateral / Allowable Lateral) 1.0.
<br />10. To account for shrinkage up to 3%, multiply rotational stiffness by 0.75. Reduction may be linearly interpolated for shrin e less than 3%.
