HCA Hinge Connectors

HCA

On This Page

Hinge connectors are designed to transfer loads between two beams aligned end-to-end through a combination of bearing plates, side plates and bolts. In addition to supporting vertical loads, hinge connectors can also be specified with additional slotted bolt holes to resist horizontal loads as part of a continuous load path. They can also be ordered to accommodate dapping or notching on the top of the beam. See Hinge Connector Specifier Guide.

Material

  • Side plates — 7 gauge; top and bottom plates — see PT dimensions in Allowable Download table

Finish

  • Simpson Strong-Tie gray paint

Installation

  • Use all specified fasteners; see General Notes
  • Bolt holes shall be a minimum of 1/32" and a maximum of 1/16" larger than the bolt diameter (per 2015 NDS 12.1.2.2)
  • The model size (suffix) column in the Allowable Download table gives the basic HCA model with two rotation bolts
  • Contact Simpson Strong-Tie for heights greater than 60"
  • Position 3/4"-diameter bolts in slots away from bearing seat to allow for wood shrinkage

Options

  • The Horizontal Load table gives other bolt options

Ordering Information

  • To order, add the width (W) and bearing plate size (PD) designation after the model name. Specify the H dimension.
  • For dapped beams, reduce the H dimension by the PT dimension for each dap. See Hinge Connector Specifier Guide.
  • Specify model no., model size and height H. Ordering Example: HC4C3TA5-6 H = 18".

Load Tables

Horizontal Load Table

HCA Hinge Connectors Horizontal Load Table
  1. Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
  2. Horizontal loads are for Douglas fir–larch glulams with minimum W = 3 1/8". For other wood types, adjust the load according to the code.
  3. H min. is the absolute minimum height. Reduce downloads according to footnote 1 in the Allowable Download table.

Allowable Download Table

HCA Hinge Connectors Allowable Download Table
  1. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Loads are based on 560 psi perpendicular-to-grain bearing stress.
  3. H1 is the minimum dimension required to achieve full load for the hinge connector. For H dimensions between H1 and Minimum H, loads may be linearly interpolated.
  4. See Horizontal Load table for models available with three rotation bolts.
  5. Beams must be the same width for both members in the connection.
