Cold-Formed Steel: MAS Mudsill Anchor

The new MASA and MASAP mudsill anchors are easy to install for both the concrete and framing contractor. The anchors are suitable for either stemwall or slab foundations and easily mount on the forms before the pour, simplifying finishing and reducing anchor mislocation problems. The MASA features higher loads and provides an alternative to 5/8" and 1/2" anchor bolts. The MASA eliminates both the need to drill bolt holes in the track and the need for 3" square-plate washers.

The different models of mudsill anchors are designed for specific applications:
MASA — installed at the top of the form
MASAP — for panelized forms

Material: 54 mil (16 ga).

Finish: Galvanized. All available in ZMAX® coating; see Corrosion Information.

Installation:

Use all specified fasteners. See General Notes
MASA/MASAP
- Concrete shall have a minimum f'_c = 2500 psi.
- Spalling — Full published capacity is achieved so long as a maximum height of 1 1/4" and a maximum depth of 7/8" is not exceeded. Any exposed portion of the mudsill anchor must be protected against possible corrosion.
- Testing shows that these mudsill anchors can be used in lieu of code-required anchor bolts and square washers in high seismic zones.

ALLOWABLE LOADS FOR MASA/MASAP CAST-IN-PLACE MUDSILL ANCHOR ON CFS SILL Table

Allowable loads are governed by tests and may not be increased (C_D = 1.0).
To obtain the LRFD loads, the tabulated allowable (ASD) loads shall be multiplied by 1.6 for designs for wind and in SDC A & B, and by 1.43 for designs in SDC C through F.
Minimum concrete compression strength, f’c is 2500 psi.
Allowable loads are based on a minimum stemwall width of 6".
For simultaneous loads in more than one direction, the connector must be evaluated using the Unity Equation. See Instructions to the Designer, paragraph b.
Per Section 1613 of the 2006 IBC, detached one- and two- family dwellings in SDC C may use the “Wind & SDC A&B” allowable loads.
Parallel-to-Track loads for One-Leg-Up Installation: Wind and SDC A-B = 1000 lbs, SDC C-F = 835 lbs.
MASA/P loads are based on testing procedures and calculations from ICC-ES Acceptance Criteria, AC398.
