The MIDPLY™ Shearwall System has been developed by Forintek. The system is designed to provide superior resistance to earthquake and wind loads. The improved performance is achieved by rearrangement of wall framing components and sheathing used in standard shear walls. Possible applications of the system are
a) platform-frame construction where additional lateral load capacity is needed (e.g., narrow shear walls next to garage and large window openings);
b) post and beam construction (e.g., as an insert between posts and beams);
c) seismic upgrading of existing structures; and
d) manufactured housing systems directed at areas with high risk of earthquakes and hurricanes.
The proof-of-concept for the MIDPLY™ wall system design and construction method was established through testing and analysis of full-scale test specimens subjected to monotonic (ramp), cyclic and dynamic displacement schedules. A commercialisation plan was developed and distributed to project collaborators.
The MIDPLY™ wall system is currently being considered by a large Canadian construction company in the design of several multi-storey wood-frame buildings.
