THIS VIDEO IS PART OF YOUR PROPOSAL AND CONTAINS EVERYTHING YOU NEED TO KNOW ABOUT SHEAR TRANSFER TIES
Shear Transfer Ties (Attaching the Floor to the Cripple Walls)
Figure 3 shows plywood bolted to the foundation. Shear Transfer Ties prevent the floor from sliding on top of the bolted and plywood braced cripple wall. Shear Transfer Ties made of steel attach the floor to the cripple wall. This completes the final stage of a cripple wall to shear wall conversion.
- All seismic retrofit guidelines require the installation of shear transfer ties. Be sure you have the right one. Many shear transfer ties on the market don’t do anything at all.
Earthquake simulation testing on shear transfer ties tell us ow much resistance a particular shear transfer ties has. Always check to see that you are using the highest strength shear transfer ties available.
Below is another kind of Shear Transfer Ties, there are many others.
Using Plywood Blocks for Shear Transfer Ties
In older homes, contractors on occasion did not install blocking between the joists. This can cause the joists to roll over like dominoes. Lock blocks prevent this.
Sometimes it is not possible to connect the floor to the floor joists with steel or plywood blocks in which case one must staple the plywood directly to the floor.
