ECCLQM End Column Cap, L-Shaped for GFCMU and Concrete Piers
On This Page
The ECCLQM embedded column cap is designed for use in raised pier foundations and applications where heavy beams rest on concrete or concrete block columns. The heavy-gauge beam seat and unique Simpson Strong-Tie® SSTB® anchor bolts provide the high uplift and lateral resistance needed to help resist high-wind events. The ECCLQM-KT is intended for use at the building corners.
MSTQM straps to make the connection from the ECCLQM to the wall framing
Screws are configured to provide high uplift design values
Certified welds for confidence in strength and loading
SSTB offset allows flush installation to edge of pier
Install 1/4" x 2 1/2" Strong-Drive® SDS Heavy-Duty Connector screws (provided) in all round holes. (Lag screws will not achieve the same load.)
Min. (4) #7 vertical rebar (total for pier).
No additional welding is allowed.
Available in widths up to nominal 7-1/8" width.
For variable widths on side stirrups, specify W3 (3 1/4" to 7 1/8") and add an “X” to the end of the core model name. Example: ECCLQM5.50GX-KT, W3 = 3 5/8".
Configurations for many different beams or beam-to-beam combinations can be manufactured (refer to worksheet Options for Column Caps for Concrete-Filled Pilasters, Grout-Filled CMU or Concrete Piers, T-C-CCQM-WS).
16" Square CMU Shell Filled with 3,000 psi Concrete3,7
Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
Total uplift load and lateral load is based on tested anchor failure in the pier.
Allowable loads are based on either a 16" square grout-filled CMU pier with f'm of 1,500 psi or a 16" square CMU shell filled with 3,000 psi concrete. A minimum of (4) #7 vertical rebars are required. The designer shall design and detail the GFCMU/concrete pier to resist all forces including uplift, shear and moment.
Pier height per designer.
Side beam and main beam uplift loads assume DF/SP members and are not additive.
The allowable loads listed for grout-filled CMU apply to solid concrete piers of 2,500 psi concrete a minimum of 16" square.
The allowable loads listed for CMU shell-filled with 3,000 psi concrete apply to solid concrete piers of 3,000 psi concrete a minimum of 14" square.
The ECCLQM-KT is a kit packaged with (2) MSTQM straps and (32) 1/4" x 2 1/2" Strong-Drive® SDS Heavy-Duty Connector screws. One strap may be installed on each face of the ECCLQM, using the SDS Heavy-Duty Connector screws in the beams and (26) 0.162" x 2 1/2" nails (not provided) in the wall framing. The MSTQM strap's allowable tension load is 6,240 lb. If straps are not installed, table uplift applies to beam only.
Any side stirrup not fully supported by grout- or concrete-filled CMU has an allowable download of 7,000 lb.
