Abstract
A timber-concrete composite floor or roof system connector that provides high slip modulus stiffness and resiliency through a combination of mechanical and adhesive connections to a timber substrate, ductile structural behavior under ultimate loading, and an integrated method for chair support of concrete slab reinforcing members during wet concrete placement.
Claims25
A timber-concrete composite connector comprising:
- a steel base plate which is configured to be attached to a timber substrate and which when attached to the timber substrate achieves a rigid connection with the timber substrate, the steel base plate extending along a longitudinal direction;
- and
- a steel top bar unitary with or secured to the steel base plate and which has at least one steel top bar module that is designed to yield under ultimate horizontal shear loads applied in the longitudinal direction and experience linear or effectively linear plastic deformation under the ultimate loads while the steel base plate and timber substrate remain elastic, the steel top bar extending along the longitudinal direction with the at least one steel top bar module located on an effective plane which is perpendicular to a plane of the steel base plate, the at least one steel top bar module (a) having two inclined legs, which are relatively straight segments that are inclined toward each other relative to the longitudinal direction, and (b) having a relatively horizontal segment between the two inclined legs.

- and
- a chair formed in the steel top bar in the form of a dip in the horizontal segment and that can receive a reinforcement bar extending transverse to the longitudinal direction.
