Simpson Strong-Tie offers the patented pre-engineered MFSL anchorage assembly to make specification and installation of anchorage as simple as possible. The unique shear-lug design provides a complete solution meeting the 2009 and 2012 International Building Code requirements for both tension and shear. These solutions come with pre-installed shear lugs.

MFSL anchorage assemblies are fully assembled and include a template which allows easy positioning and attachment to forms prior to the pour. Inspection is easy since the head is stamped with the "No Equal" (≠) symbol for identification, bolt length, bolt diameter, and optional "H" for high strength (if specified).

Installation

Concrete must be thoroughly vibrated around the shear lug to ensure full consolidation of the concrete around the assembly.

MFSL Anchorage Assembly Shear Lug Capacities - ASD Wind Shear Capacity (lbs)
MFSL Anchorage Assembly Shear Lug Capacities - ASD Wind Shear Capacity (lbs)
  1. Seismic includes designs in all Seismic Design Categories.
  2. Shear lug is included with MFSL anchorage assembly.
  3. End distance is measured from centerline of nearest anchor bolt to edge of concrete.
  4. First load value listed for each column corresponds to pre-installed wood nailer flush with end of concrete (see base plate plans).
  5. Designer may linearly interpolate for end distances between those listed.
  6. LRFD capacities may be obtained by multiplying tabulated values by 1.6 for wind or by dividing tabulated values by 0.7 for seismic.
  7. Solutions are base on standard strength MFSL_-__-KT anchorage assembly, except shaded values, where high strength MFSL_-__HS-KT anchorage assembly is required.
  8. See tension anchorage solutions for additional anchorage assembly strength requirements. Use high strength OMFSL_-__HS-KT anchorage assembly where required by either shear or tension anchorage.
  9. See tension anchorage solutions.
