Dowel design of the shear plate dowel joint - ScienceDirect

Apr 15, 2020 · Ductility can be introduced in the shear plate dowel joint by using metal tubes as the load transferring dowel, but typically at the expense of total load carrying capacity. In addition to load transfer by shear, the total load carrying capacity of the shear plate dowel joint can be increased by contact between the dowel and timber element.

Lockable Dowels STRUCTURAL TECHNOLOGIES

Lockable Dowels improve site access, minimize formwork requirements and accelerate the rate of construction. With a Lockable Dowel, there is less requirement for the slabs to be propped or a support corbel to be constructed, as shear load is transferred by the dowel. The time saved by early removal of slab props can be significant. Performance Comparison Ancon Australia1 Ancon DSD 130 Design Capacity 202.5kN 6 Dowel Bars 32mm Diameter Design Capacity 197.5kN
