CCOS Steel-Column Cap

CCOS

On This Page

The CCOS provides a high-capacity connection for column-to-beam combinations. This design without the column straps was created specifically for field welding to a steel column. For faster installation, the CCOS requires that Simpson Strong-Tie Quik Drive® screws be used to attach the column cap to the column cap plate.

Key Features

  • Simpson Strong-Tie Quik Drive self-tapping screws included
  • Provides adequate bearing length for larger girder reactions
  • Sizes available for both solid sawn lumber and engineered wood products

Material

  • 7 gauge

Finish

  • Galvanized (G90)

Installation

  • Use all specified fasteners; see General Notes.
  • Attach steel column cap to column end plate with (4) CCOS tap screws (provided) and attach to girder. Install with 5/16"-hex driver.

Download 1,2,3 Uplift F1
DF/SP/SPF LVL/PSL/LSL (160) (160)
  1. Loads may not be increased for short-term loading.
  2. Allowable loads are determined using the lowest of the bearing loads using Fc-perp equal to 425 psi for SPF, 625 psi for DF and 700 psi for LVL/PSL/LSL.
  3. Loads are for a continuous beam.
  4. The CCOS must be attached to the column cap plate with (4) CCOS self-tapping screws through the end plate and into the bottom of the CCOS. Max column cap plate thickness = 1/2" and 3/16" Min.
  5. All pipe columns need to be designed by a qualified designer. CCOS minimum column diameter is 3".
  6. CCOS caps can resist out-of-plane (F2) forces up to 2120 lbs. provided the beam is braced to resist torsional rotation.
  7. NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long.
  8. See other nail sizes and information.
