Shearmax – Shear Transfer Systems
Want to achieve similar shear capacity as squash block systems but have concerns about wood shrinkage? Simplify the load path and take advantage of custom heights by using tall panels from concrete to second floor top plate or if one is not enough consider using back-to-back panels instead of stacked panels.

DESIGN OF ANCHOR BOLTS EMBEDDED IN CONCRETE MASONRY - NCMA
INTRODUCTION. The function of anchor bolts is to transfer loads to the masonry from attachments such as ledgers sills and bearing plates. Both shear and tension are transferred through anchor bolts to resist design forces such as uplift due to wind at the top of a column or wall or vertical gravity loads on ledgers supporting joists or trusses (see Figure 1).

Lag shields produce strong joints but they involve more installation steps than most fasteners. First drill holes through the wood sole plate with a wood bit and mark the floor. Move the sole plate drill the floor suck out the dust and tap the shield into place. Replace the sole plate and drive lag screws with washers into the shields.

Choosing the Best Anchor to Fasten to Concrete - Concrete
An object placed on a wall puts the concrete fastener into a shear loading situation (the load is at a 90° angle to the anchor). The shear values are based on the diameter of the anchor and are not affected by embedment depth. The larger the diameter the better the shear values will be.

Once the shear forces are calculated they are then distributed to the shear wall via floor and/or roof sheathing (or in engineering term roof or floor diaphragm). The anchor bolts spacing are determined by dividing the total force in a given wall by the total length of the wall which will determine the anchor bolt spacing.

Assume that anchor bolts 12" o.c. are used to transfer the shear out of the shear wall panel. The wall shear is a per foot load. It is transferred out of the wall sheathing by nails into the bottom plate so the bottom plate is loaded along its full length. You don't have all the load transfered into the plate then into the anchor bolts.

Behaviour factor for innovative massive timber shear walls
Four massive wooden shear walls were analysed via experimental tests and numerical simulations. The specimens differ mainly in the method used to assemble the layers of timber boards: two of them are the well-known Cross-Laminated-Timber panels with glued interfaces the other two are innovative massive timber panels adopting steel staples or wooden dovetail inserts to connect the layers.
Overturning Shear Walls in Seismic Retrofit Work
Why short and wide shear walls don’t need Hold Downs. Using the same principle if you have a 12-foot-long shear wall 2 feet tall that must resist 3600 pounds at the top (300 pounds per linear foot) the overturning will only be 600 pounds on each end (2 x 300 pounds per linear foot) and the weight of the house is sufficient to resist this force.
