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).

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.

Anchor bolt spacing of wood to concrete - Moment Frame

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.

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.
