The CBS column base installs with bolts and provides tested capacity. The 1" standoff (included) meets code requirements for structural posts installed in basements or exposed to weather or water splash.
Galvanized; available in HDG
Use all specified fasteners; see General Notes
Install with two bolts
For full loads, a minimum of 3" side cover shall be provided
Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations (such as fences or unbraced carports)
For higher downloads, pack grout solid under 1" standoff plate before installation. Base download on column or concrete, according to the code.
Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
To obtain LRFD values, multiply ASD seismic load values by 1.4 and wind load values by 1.67 (1.6 for 2012 IBC).
In accordance with IBC, Section 1613.1, detached one- and two-family dwellings in Seismic Design Category (SDC) C may use "Wind and SDC A&B" allowable loads.
Downloads shall be reduced where limited by capacity of the post.
Designer is responsible for concrete design.
Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers known as the narrow face. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for load reductions resulting from narrow-face installations.
