Description:

The ABU Adjustable Post Base provides a high‑strength connection between the post and concrete. Designed to install on hardened concrete with either a cast‑in‑place or post‑installed anchor, the ABU is designed to provide strong uplift performance for areas where uplift from high winds is a concern. It's stand-off base keeps the timber away from standing moisture which is especially important when using laminated posts.

Please check Corrosion Information if it is suitable for your application.

Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the Australian Capacity Factor, or the NZ Strength Reduction Factor (φ), and applicable the k modification factors following AS 1720.1 and NZS 3603 and (2) the Serviceability Capacity which is the load at 3.2mm joint slip. Design Capacity is the minimum of test data and structural joint calculation. For Australia, the Capacity Factor (φ) is 0.85 for nails and screws for structural joints in a Category 1 application. Reduce tabulated values where other Category applications govern. For NZ, the Strength Reduction Factor (φ) is 0.80 for nails in lateral load and 0.70 for other fasteners. Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased. Timber species for joint design is seasoned Radiata Pine, which is Australia Joint Group JD4 per AS 1720.1 Table H2.4 and New Zealand Joint Group J5 per NZS 3603 Table 4.1. Specifier to design concrete for uplift capacity. Structural composite timber columns have sides that either show the wide face or the edges of the timber strands/ veneers, known as the narrow face. Fasteners should be installed in the wide face. Simpson Strong-Tie stainless-steel connectors require stainless-steel fasteners. HB dimension is the distance from the bottom of the post up to the first bolt hole. Downloads shall be reduced where limited by the capacity of the timber post.
