Moment resisting self-tapping screw assembly under monotonic and reverse cyclic load

One of the most significant fastener alternatives in the market of timber construction is the emergence of self-tapping wood screws (STS). This fastener has primarily been developed to reinforce the weakest strength properties of wood. To extent the application possibility of STS in timber construction, future research needs to address the potential of such screws not just as reinforcement but as active connector. If STS can be applied as a connector in timber construction at desirable cost and safety, this fastener will help the timber industry penetrate into building sectors where performance is of prime importance. This would include commercial and residential buildings all over North America. The proposed research will establish a much needed database for STS connections under seismic loads. The combination of literature reviews and experiments will allow engineers in North America to apply this fastener not just as reinforcement but as active connector in timber structures.
